Stratifyd & MongoDB: AI-Driven Business Insights to Keep Customers Happy

2017 was a banner year for MongoDB's partner ecosystem. We remain strategic about engaging with our channels, and the results are validating our approach. Our strong network of ISVs, global system integrators, cloud, resellers, and technology partners is a competitive differentiator that helps us scale.

We are especially excited about the innovation and growth in store for our ISV business in 2018. It's already off to a great start. Our newest ISV partner Stratifyd is a fantastic example of how platforms built around MongoDB address serious market needs with the most cutting-edge, innovative technology.

Stratifyd is an end-to-end customer analytics platform powered by AI. The platform provides competitive advantages to some of the most recognized brands in the world. LivePerson, Etsy, MASCO, Kimberly-Clark, and many more rely on Stratifyd for a 360-degree view of their end customers.

Stratifyd analyzes customer interactions such as online reviews, social media posts, phone calls, emails, chats, surveys, CRM data, and more to turn them into actionable business insights which increase customer acquisition and retention, which is critical to the continued success of Stratifyd’s clients. In addition to these benefits, Stratifyd is just a flat-out cool implementation of AI.

I caught up with Stratifyd's CTO, Kevin O'Dell, to discuss the data technology behind the platform, and how MongoDB drives value for their customers.


For anyone that isn’t familiar with Stratifyd yet, how do you describe the platform?

Stratifyd uses human generated data to analyze, categorize, and understand intent with the purpose of changing human behavior. This changes the way brands interact with their customers, but also the way customers interact with brands, increasing customer acquisition and raising retention rates.

What was the genesis of the company? Why did you set out to build this?

Stratifyd was a result of postdoctoral research done at the University of North Carolina, Charlotte. Our founders were researching how AI could analyze unstructured data. During their research, they discovered strong business and government use cases. The founding team was working with numerous three letter agencies on predicting terrorist and disease movements globally. They were able to raise millions of dollars in funding from these agencies. The demand for a product organically grew from there, which led to the development of the Stratifyd platform.

I love the insights Stratifyd can provide – how would you describe the unique advantages that Stratifyd gives its customers?

Stratifyd provides near real-time business intelligence for contact center, marketing, product, and customer experience teams, all based on customer interactions. These insights enable businesses to be proactive rather than reactive in regard to business strategy. Stratifyd customers are able to respond to customer requests, complaints, or general feedback in near real time, changing the way companies interact with their end users. For example, we have empowered a customer with the knowledge to launch a new product line. Another customer gained insights that fundamentally changed how they are rolling out a 700+ million-dollar brand in a new continent.

What kind of feedback are you getting from customers that have deployed Stratifyd in their businesses?

Our customers love using our platform. They are surprised at how simple it is to use, and how powerful it is. They really appreciate how Stratifyd is making AI and machine learning meaningful for them in their day-to day-lives. Stratifyd helps ensure measurable results from day one. Speaking of implementation, they REALLY love that we don’t just use the term day one figuratively – customers are up and running in less than a day.

Talk to me about how you landed on MongoDB. What were you looking for in a database, and what problems were you having before moving to MongoDB?

That's an easy one to answer: speed and flexibility. Stratifyd ingests data from hundreds of sources. We needed a database that could keep up with high read and write request rates while handling a flexible schema. The hardest problem we were trying to solve was lack of secondary indexes; with those, MongoDB accelerated our query response times by at least 100x.

Can you share any best practices for scaling your MongoDB infrastructure? Any impressive metrics around the number of interactions, the volume of reads / writes per second, response times?

As a SaaS-first platform, being always-on is a HUGE best practice for us. MongoDB’s innate replication and failover abilities ensured less than 17 minutes of total downtime last year! Using MongoDB as our backend system, our AI can process a quarter of a million words in less than a minute.

How do you measure the impact of MongoDB on your business?

Our business wouldn’t be able to succeed without MongoDB. The uptime, failover, query response times, secondary indexes, and dynamic schemas have empowered most of Stratifyd’s key differentiators.

What advice would you give someone who is considering using MongoDB for their next project?

With all projects, I recommend truly understanding the requirements for the end results. There is a ton of excellent technology out there, but picking the wrong one can be detrimental to project success. Always run numerous tests, comparing different stacks to make sure you find the right one and fail fast on the wrong technology stack.

Stratifyd has some impressive customers, from the Fortune 500 to some really innovative startups: what’s next for the company?

We have some pretty big things planned for 2018. We're now providing more than just actionable intelligence; we are now streamlining and automating workflows. We are closing the customer feedback loop, which enables us to plug Stratifyd into any business process quickly to deliver measurable results.

DarwinBox Evolves HR SaaS Platform and Prepares for 10x Growth with MongoDB Atlas

DarwinBox found a receptive market for its HR SaaS platform for medium to large businesses, but rapid success strained their infrastructure and challenged their resources. We talked to Chaitanya Peddi, Co-founder and Head of Product to find out how they addressed those challenges with MongoDB Atlas.

Evolution favors those that find ways to thrive in changing environments. DarwinBox has done just that, providing a full spectrum of HR services online and going from a standing start to a top-four sector brand in the Indian market in just two years. From 40 enterprise clients in its first year to more than 80 in its second, it now supports over 200,000 employees, and is hungrily eyeing expansion in new territories.

“We’re expecting 10x growth in the next two years,” says Peddi. “That means aggressive scaling for our platform and MongoDB Atlas will play a big role."

Starting from a blank sheet of paper

The company’s key business insight is that employees have grown accustomed to the user experience of online services they access in their personal lives. However, the same ease of use is simply not found at work, especially in HR solutions that address holiday booking, managing benefits, and appraisals. DarwinBox’s approach is to deliver a unified platform of user-friendly HR services to replace a jumble of disparate offerings, and to do so in a way that supports its own aggressive growth plans. The company aims to support nearly every employee interaction with corporate HR, such as recruitment, employee engagement, expense management, separation, and more.

“We started in 2015 from a blank sheet of paper,” Peddi says. “It became very clear very quickly that for most of our use cases, only a non-relational database would work. Not only did we want to provide an exceptionally broad set of integrated services, but we also had clients with a large number of customization requirements. This meant we needed a very flexible data model. We looked at a lot of options. We wanted an open source technology to avoid lock-in and our developers pushed for MongoDB, which fit all our requirements and was a pleasure to work with. Our databases are now 90 percent MongoDB. We expect that to be at 100 percent soon.”

Reducing costs and future-proofing database management

When DarwinBox launched, it ran its databases in-house, which wasn’t ideal. “We have a team of 40+ developers, QA and testers, and three running infrastructure, and suddenly we’re growing much faster than we expected. It’s a good problem to have, but we couldn’t afford to offer anything less than excellent service.” Peddi emphaszied that of all the things they wanted to do to succeed, becoming database management experts wasn’t high on the list.

This wasn’t the only reason that MongoDB Atlas looked like the next logical step for the company when it became available, says Peddi, “We were rapidly developing our services and our customer base, but our strategies for backing up the databases, for scaling, for high availability, and for monitoring performance weren’t keeping up. In the end, we decided that we’d migrate to Atlas for a few major reasons.”

The first reason was the most obvious. “The costs of managing the databases, infrastructure, and backups were increasing. In addition, it became increasingly difficult to self-manage everything as requirements became more sophisticated and change requests became more frequent. Scaling up and down to match demand and launching new clusters consumed precious man hours. Monitoring performance and issue resolution was taking up more time than we wanted. We had built custom scripts, but they weren’t really up to the task.”

With MongoDB Atlas on AWS, Peddi says, all these issues are greatly reduced. “We’re able to do everything we need with our fully managed database very quickly – scale according to business need at the press of a button, for example. There are other benefits. With MongoDB technical engineers a phone call away, we’re able to fix issues far quicker than we could in the past. MongoDB Compass, the GUI for the database, is proving helpful in letting our teams visually explore our data and tune things accordingly.”

Migrating to Atlas has also helped Darwinbox dramatically reduce costs.

We’ve optimized our database infrastructure and how we manage backups. Not only did we bring down costs by 40%, but by leveraging the queryable snapshot feature, we’re able to restore the data we actually need 80% faster.

Chaitanya Peddi, Co-founder and Head of Product, DarwinBox

The increased availability and data resilience from the switch to MongoDB Atlas on AWS eases the responsibility in managing the details of 200,000 employees’ working lives. “Data is the most sensitive part of our business, the number one thing that we care about,” says Peddi, “We can’t lose even 0.00001 percent of our data. We used to take snapshots of the database, but that was costly and difficult to manage. Now, it’s more a live copy process. We can guarantee data retention for over a year, and it only takes a few moments to find what you need with MongoDB Atlas.”

For DarwinBox to achieve its target of 10x growth in two years, it has to – and plans to – go international.

“We had that in mind from the outset. We’ve designed our architecture to cope with a much larger scale, both in total employee numbers and client numbers, and to handle different regulatory regimes.” According to Peddi, that means moving to microservices, developing data analytics, maybe even looking at other cloud providers to host the DarwinBox HR Platform. He added: “If we were to do this on AWS and self-manage the database with our current resources, we would have to invest a significant amount of effort into orchestrating and maintaining a globally distributed database. MongoDB Atlas with its cross-region capabilities makes this all much easier.”

Darwinbox is confident that MongoDB Atlas will help the organization achieve its product plans.

“MongoDB Atlas will be able to support the business needs that we've planned out for the next two years.” says Peddi, “We’re happy to see how rapidly the Atlas product roadmap is evolving.”

BookMyShow Continues to Lead Online Entertainment Ticketing in India and Scales to 25 Million Users with MongoDB

India's twin passions for cinema and tech make it a natural fit for automated ticketing. But if ever a market needs scalable solutions, this 1.4 billion-strong nation is it.

That’s a lesson Viraj Patel, VP Technology for BigTree Entertainment, learned the hard way. "We started out in ticketing distribution in 1999 using telephones," he says, "before mobile platforms and internet access were on the scene. It just didn't work. The investors pulled the plug in 2002.”

Undeterred, the company successfully pivoted to selling software to cinema chains. By 2006, Viraj and team were ready to aim for the big prize again. They just needed the right tools. With the internet and mobile data fitting into place, a trial project in online ticket aggregation looked promising enough for investors to fund the launch of BookMyShow in 2007.

“We launched with a 100 percent Microsoft stack,” says Viraj, “but soon realized that scaling with Microsoft was not an easy job.” It wasn’t the Windows platform or the developer tools that were the problem, he recalls: “It was the SQL Server database. That was the first bottleneck as we got more and more traffic, and it soaked up more and more resources and money. It wasn’t the right solution. It couldn’t scale with us.”

Spoiler: By 2018, BookMyShow, each month, sells more than 10 million tickets for all manner of movies and events and serves three billion pages a month across the web and its 50 million plus installed apps. Scaling happened.

The plot changed for the better in 2010 with the discovery of MongoDB. “We were looking around for alternatives, and it was the new kid on the block.” (In fact, MongoDB 1.0 had launched just the year before, and MongoDB India was yet to come.) “We tested it internally as a straight distributed database for monolithic SQL database swap. Every web and mobile application we built needed a database that had performance and scalability, and MongoDB blew us away on both.”

MongoDB really won its spurs when the company added Facebook Connect to its registration process. “The registration database was the first thing we built, and it was running on SQL Server. Which was OK, until Facebook Connect came along and we added that as a registration option. Then the database really struggled. We switched to MongoDB and it was night and day. Tremendous gains. Not only did we get the ability to represent customers directly as JSON documents in the database, which made our data model much simpler, but we got all our performance back.

“We want the flexibility of upgrading the schema for future use cases, and that’s so much easier in MongoDB. The data structures we create are clear and easy to read, and it’s so much simpler to understand and extend,” Viraj adds, about their discovery of the advantages of document-model storage.

MongoDB’s second big job was also thoroughly web scale, as it took on the task of giving each of those millions of users their own bespoke, personalized view of the service. This time, the engineering team knew where to start. “About five years ago, we built our personalization engine on MongoDB,” says Viraj, “and it continues to scale with us. It stores a lot of customer information and when a customer visits, it pulls it out, personalizes it in real time and delivers it. That really improves the customer experience. We see an 18 percent increase in conversion, personalized versus non-personalized.”

Today, MongoDB is the default database for developing ideas and services in BigTree, and Viraj cheerfully admits he has long ago stopped counting how many nodes are in use. “Last time I looked, it was between 100-160,” he says.

Future plans include containerization of the databases to smooth out upgrades and ease of deployment with BigTree’s agile DevOps production pipeline and, when the time comes, sharding the customer database. That’s planned for, but not currently necessary. He explains: “We just haven’t reached the point where writes to MongoDB are the limiting factor anywhere in the service. We get a long way with MongoDB replica sets, and are safe in the knowledge that there are no limitations to scaling further when we need to.”

Viraj cares deeply about latency – “We’re a performance-sensitive company” – and much of the service is instrumented by monitoring and management platforms such as New Relic. While initial performance gains were superlative, he says, things have only continued to improve as new features and technologies have been added. “We had been using SQL tabular databases for customer booking history,” says Viraj. “We moved this to MongoDB and have seen a superb performance boost. What used to take up to 5000 ms on traditional SQL databases went down to 10-20 ms on MongoDB using the MMAP storage engine. When we moved to MongoDB’s default WiredTiger storage engine, it improved five to ten times further, to 2ms. We’re still getting this performance, even though the database now has close to 200 million documents.”

There have been other benefits from following MongoDB’s roadmap. “WiredTiger has made things much more cost-effective,” he says. “Security is better as we now encrypt data instead of storing it in plain JSON. Our customer database is five times more compact and our personalization database uses nearly eight times less storage.”

In the future, he says, they expect aggregation queries and query caching mechanisms will improve performance still more. As for reliability, “MongoDB auto-heals so well in the event of any failures in our platform we don’t even need to worry about it. That’s highly appreciated, and much better than any of the other databases we have used.”

There can be few better stories of early adoption and innovation with MongoDB than the success BigTree Entertainment has enjoyed with BookMyShow. Viraj and his engineers insist on picking the right tools for each part of the job running India’s favourite online ticketing service, their long experience of casting this particular actor in so many roles makes MongoDB a performer they’ve come to rely on.

Future Facilities Triples the Speed of Development with MongoDB

Future Facilities is an OEM partner of MongoDB that helps engineers and IT professionals use virtual prototyping to better plan IT deployments within data centers. By leveraging Computational Fluid Dynamics (CFD) simulation, users can test what-if scenarios unique to their facilities. Their web-based platform was originally built on MySQL, but the team quickly realized that the database couldn’t scale to meet their needs.

Instead, Future Facilities chose to migrate to MongoDB Enterprise Advanced. We sat down with Akhil Docca, Corporate Marketing & Product Strategy Manager of Future Facilities, to learn how migrating to MongoDB helped to triple the speed of development.


Can you tell us a little bit about yourself and Future Facilities?

I lead the marketing and product strategy here at Future Facilities. We provide software and services specifically focused on physical infrastructure design and management to customers in the data center market. Our solutions span the entire data center ecosystem, from design to operations. By utilizing a digital clone that we call the Virtual Facility (VF), our users can see the impact of any change like adding new capacity, upgrading equipment, etc., before it is implemented.

In 2004 we released 6SigmaRoom, the data center industry’s leading CFD software for data centers. 6SigmaRoom is how our users create a VF, where they can input live data from their facility, and include necessary objects such as cooling and power units, servers and racks. Having this digital twin allows engineers to troubleshoot, predict and analyze the impact of any deployment plan, and find the optimal method for implementation. With 6SigmaRoom, engineers can speed up capacity planning and improve the overall efficiency and resilience of their data center.

6SigmaRoom is essential for accurate data center capacity planning, however, it’s a heavy-duty desktop application developed for engineers. We wanted to create a product that Facilities and IT teams could use to improve both their processes and overall data center performance. In 2016 we launched a new product, 6SigmaAccess, to do just that.

6SigmaAccess is a multi-user, browser-based software platform that allows IT professionals to interact with their data center model and propose changes through a central management system. The browser-based architecture allows us to load up a lighter version of the 3D model specifically tailored to the IT capacity planning process.

Here’s how it works. IT planners propose changes such as adding new IT or racks, decommissioning equipment or cabinets, or simply editing attributes. These changes are then submitted and queued up via MongoDB. When the data center engineer opens up 6SigmaRoom, the proposed changes are automatically merged, allowing the engineer to simply run the simulation to see how the changes would affect the facility. If the analysis reveals that the proposed installations don’t impact performance, they can then be approved, merged back into the database and scheduled for deployment

MongoDB is the integration layer between 6SigmaAccess and 6SigmaRoom that makes this process possible.

What were you using before MongoDB?

We initially started building on MySQL, but quickly ran into challenges. Whenever we wanted to make an update to the database schema, there would be a huge demand on time and resources from our developers, DBAs, and ops teams. It quickly became apparent that we wouldn’t be able to scale to meet the needs of our customers. While redesigning the platform, we knew that we had to get away from the rigid architecture of a SQL tabular database.

Our goal was to find a data platform that was easy to work with, that developers would like, and that could scale as our business grew. After briefly considering Cassandra and CouchDB, we selected MongoDB for its strong community ecosystem, which made adopting the technology seamless. MongoDB allows us to focus on delivering new features instead of having to worry about managing the database. We are able to code, test and deliver incremental changes to 6SigmaAccess without having to change 6SigmaRoom. This will shorten our development cycles by 66%, from 9 to 3 months.

Can you describe your MongoDB deployment?

The key components of 6SigmaAccess are node.js, angular.js, JSON, and RESTful APIs. 6SigmaRoom is built on C++. We are currently deploying a 3-node cluster to our enterprise customers.

Our technology is built in a way that we aren’t always writing massive amounts of data to the database. 6SigmaAccess changes tend to be a few MBs at a time. 6SigmaRoom data files tend to be in the 100s of GB range, but we only write the data into the database based on a user action. The typical (minimum) server configuration that we’ve sized for our applications are: 4-16 Cores, 64 GB of RAM & 1 TB of disk space.

We are Windows Active Directory compliant and have additional access controls built into our software that enforces roles and permissions when connecting to the database.

What advice would you give someone who is considering using MongoDB for their next project?

Start early and incorporate MongoDB in your project from the beginning. Redundancy and scalability are important at the heart of any application and planning how to achieve those goals from the onset will make development much smoother down the road. Additionally, choose a vendor with a strong support team. We were extremely impressed with MongoDB’s sales and technical team prowess throughout the conversion process, and look forward to working with them in the future.

STREAM: How MongoDB Atlas and AWS help make it easier to build, scale, and personalize feeds that reach millions of users

This is a guest post by Ken Hoff of Stream (

Stream is a platform designed for building, personalizing, and scaling activity feeds that reach over 200 million users. We offer an alternative to building app feed functionality from scratch by simplifying implementation and maintenance so companies can stay focused on what makes their products unique.

Today our feed-as-a-service platform helps personalize user experiences for some of the most engaging applications and websites. For example, Product Hunt, which surfaces new products daily and allows enthusiasts to share and geek out about the latest mobile apps, websites, and tech creations, uses our API to do so.

We’ve recently been working on an application called Winds, an open source RSS and podcast application powered by Stream, that provides a new and personalized way to listen, read, and share content.

We chose MongoDB to support the first iteration of Winds as our developers found the database very easy to work with. I personally feel that the mix of data model flexibility, scalability, and rich functionality that you get with MongoDB makes it superior to what you would get out of the box with other NoSQL databases or tabular databases such as MySQL and PostgreSQL.

Our initial MongoDB deployment was managed by a vendor called Compose but that ultimately didn’t work out due to issues with availability and cost. We migrated off Compose and built our own self-managed deployment on AWS. When MongoDB’s own database as a service, MongoDB Atlas, was introduced to us, we were very interested. We wanted to reduce the operational work that our team was doing and found Atlas’s pricing much more predictable than what we had experienced with our previous MongoDB service provider. We also needed a database service that would be highly available out of the box. The fact that MongoDB Atlas sets a minimum replica set member count and automatically distributes each cluster across AWS availability zones had us sold.

The great thing about managing or scaling MongoDB with MongoDB Atlas is that pretty much almost all of the time, we don’t have to worry about it. We run our application on a deployment using the M30 size instances with the auto-expanding storage option enabled. When our disk utilization approaches 90%, Atlas automatically provisions us more with no impact to availability. And if we experience spikes in traffic like we have in the past, we can easily scale up or out using MongoDB Atlas by either clicking a few buttons in the UI or triggering a scaling event using the API.

Another benefit that MongoDB Atlas has provided us is on the cost savings side. With Atlas, we no longer need a dedicated person to worry about operations or maintaining uptime. Instead, that person can work on the projects that we’d rather have them working on. In addition, our team is able to move much faster. Not only can we make changes on the fly to our application leveraging MongoDB’s flexible data model, but we can deploy any downstream database changes on the fly or easily spin up new clusters to test new ideas. All of these can happen without impacting things in production; no worrying about provisioning infrastructure, setting up backups, monitoring, etc. It’s a real thing of beauty.

In the near future, we plan to look into utilizing change streams from MongoDB 3.6 for our Winds application, which is already undergoing some major upgrades (users can sign up for the beta here). This may eliminate the need to maintain separate Redis instances, which would further increase our savings and reduce architectural complexity.

We’re also looking into migrating more applications onto MongoDB Atlas as its built-in high availability, automation, fully managed backups, and performance optimization tools make it a no-brainer. While there are other MongoDB as a service providers out there (Compose, mLab, etc.) available, no other solution comes close to what MongoDB Atlas can provide.

Longbow Advantage - Helping companies move beyond the spreadsheet for a real-time view of logistics operations

The global market in supply chain analytics is estimated at some $2.7 billion[1] — and yet, far too often supply chain leaders use spreadsheets to manage their operation, limiting the real-time visibility into their systems.

Longbow Advantage, a supply chain partner, helps companies get the maximum ROI from their supply chain software products. Moving beyond the spreadsheet and generic enterprise BI tools, Longbow developed an application called Rebus™ which allows users to harness the power of smart data and get real-time visibility into their entire supply chain. That means ingesting data in many formats from a wide range of systems, storing it for efficient reference, and presenting it as needed to users — at scale.

MongoDB Atlas is at the heart of Rebus. We talked to Alex Wakefield, Chief Commercial Officer, to find out why they chose to trust such a critical part of their business to MongoDB and how it’s panned out both technically and commercially.


Tell us a little bit about Longbow Advantage. How did you come up with the idea?

Sixteen years ago our Founder, Gerry Brady, left his job at a distribution company to build Longbow Advantage. The goal was to build a company that could help streamline warehouse and workforce management implementations, upgrades, and integrations, and put more focus on customer experience and success.

Companies of all sizes have greatly improved distribution processes but still lack real-time visibility into their systems. While there’s a desire to use BI/analytics systems, automate manual processes, and work with information in as close to real-time as possible, most companies continue to rely on manually generated spreadsheets to measure their logistics KPIs, slowing down speed to insights.

There had to be a better way to help companies address this problem. We built an application called Rebus. This SaaS-based analytics platform, used by industry leaders such as Del Monte Foods and Subaru of America, aggregates and harmonizes logistics data from any supply chain execution software to provide a near real-time view of logistics operations and deliver cross-functional insights. The idea is quite simply to provide more accurate data in as close to real-time as technically possible within a common platform that can be shared across the supply chain.

For example, one company may have a KPI around labor productivity. When that company receives a customer order to ship, there is a lot of information they want to know:

  • Was the order shipped and on-time?
  • How efficiently is the labor staff filling orders?
  • How many orders are processing?
  • How many individual lines or tasks on the order are being filled?

The list goes on. With Rebus, manufacturers, retailers and distributors can segment different business lines like ecommerce, traditional retail, direct to consumer and more, to ensure that they are being productive and meeting the appropriate deadlines. Without this information, a company may miss major deadlines, negatively impact customer satisfaction, miss out on revenue opportunities, and in some cases, incur significant financial penalties.

What are some of the benefits that your customers are experiencing?

Our customers are able to automate a manual and time-intensive metrics process and collect near real-time data in a common platform that can be used across the organization. All of this leads to more efficient decision-making and a coordinated communication effort.

Customers are also able to identify inaccurate or duplicate data that may be contributing to slow performance in their Warehouse and Labor Management software. Rebus provides an immediate way to identify data issues and improve overall performance. This is a huge benefit for customers who are shipping thousands of orders every week.

Why did you decide to use MongoDB?

Four years ago, when we first came up with the idea for Rebus, we gathered a group of employees to brainstorm the best way to build it.

In that brainstorm, one of our employees suggested that we use MongoDB as the underlying datastore. After doing some research, it was clear that the document model was a good match for Rebus. It would allow us to gather, store, and build analytics around a lot of disparate data in close to real time. We decided to build our application on MongoDB Enterprise Advanced.

When and why did you decide to move to MongoDB Atlas?

We first heard about MongoDB Atlas in July 2016 shortly after it launched, but were not able to migrate right away. We maintain strict requirements around compliance and data management, so it was not until May 2017, when MongoDB Atlas became SOC2 compliant, that we decided to migrate. Handing off our database management to the team that builds MongoDB gave us peace of mind and has helped us stay efficient and agile. We wanted to ensure that our team could remain focused on the application and not have to worry about the underlying infrastructure. Atlas allowed us to do just that.

The migration wasn’t hard. We were moving half a terabyte of data into Atlas, which took a couple of goes — the first time didn’t take. But the support team was proactive. After working with us to pinpoint the issue, one of our key technical people reconfigured an option and the process re-ran without any issues. We hit our deadline.

Why did you decide to use Atlas on Google Cloud Platform (GCP)?

Google Cloud Platform is SOC2 compliant and allows us to keep our team highly efficient and focused on developing the application instead of managing the back end. Additionally, GCP gave us great responses that we weren’t getting from other cloud vendors.

How has your experience been so far?

MongoDB Atlas has been fantastic for us. In particular, the real-time performance panel is fantastic, allowing us to see what is going on in our cluster as it’s happening.

In comparison to other databases, both NoSQL and SQL, MongoDB provides huge benefits. Despite the fact that many of our developers have worked with relational databases their entire careers, the way we can get data out of MongoDB is unparalleled to anything they’ve ever seen. That’s even with a smaller, more efficient footprint on our system.

Additionally, the speed of MongoDB has been really helpful. We’re still looking at the results from our load tests, but the ratio of timeouts to successes was very low. Atlas outperforms what we were doing before. We know we can support at least a couple hundred users at one time. That tells us we will be able to go and grow with MongoDB Atlas for years to come.

Thank you for your time Alex.

Powering an online community of coders with MongoDB Atlas

This is a guest post by Linda Peng (creator of CodeBuddies) and Dhaval Tanna (core contributor).

If you’re learning to code, or if you already have coding experience, it helps to have other people around -- like mentors, coworkers, hackathon buddies and study partners -- to help accelerate your learning, especially when you get stuck.

But not everyone can commute to a tech meetup, or lives in a city with access to a network of study partners or mentors/coworkers who can help them.

CodeBuddies started in 2014 as a free virtual space for independent code learners to share knowledge and help each other learn. It is fully remote and 100% volunteer-driven, and helps those who — due to geography, schedule or personal responsibilities — might not be able to easily attend in-person tech meetups and workshops/hackathons where they could find study partners and mentors.

The community is now comprised of a mix of experienced software engineers and beginning coders from countries around the world, who share advice and knowledge in a friendly Slack community. Members also use the website at to start study groups and schedule virtual hangouts. We have a pay-it-forward mentality.

The platform, an open-sourced project, was painstakingly built by volunteer contributors to help members organize study groups and schedule focused hangouts to learn together. In those peer-to-peer organized remote hangouts, the scheduler of the hangout might invite others to join them in:

  • Working through a coding exercise together
  • Screen sharing and helping each other through a contribution to an open-sourced project
  • Co-working silently in a “silent” hangout (peer motivation)
  • Helping them practice their knowledge of a topic by attempting to teach it
  • Reading through a chapter of a programming tutorial together

Occasionally, the experience will be magical: a single hangout on a popular framework might have participants joining in at the same time from Australia, the U.S., Finland, Hong Kong, and Nigeria.

The site uses the MeteorJS framework, and the data is stored in a MongoDB database.

For years, with a zero budget, CodeBuddies was hosted on a sandbox instance from mLab. When we had the opportunity to migrate to MongoDB Atlas, our database was small enough that we didn’t need to use live migration (which requires a paid mLab plan), but could migrate it manually. These are the three easy steps we took to complete the migration:

1) Dump the mongo database to a local folder

Once you have stopped application writes to your old database, run:

mongodump -h --port 15992 --db production-database -u username -p password -o Downloads/dump/production-database

2) Create a new cluster on MongoDB Atlas


3) Use mongorestore to populate the dumped DB into the MongoDB Atlas cluster

  First, whitelist your droplet IP on MongoDB Atlas:

Then you can restore the mlab dump you have in a local folder to MongoDB Atlas:

mongorestore --host --port 27018 --authenticationDatabase admin --ssl  -u username -p password Downloads/dump/production-database

We host our app on DigitalOcean, and use Phusion Passenger to manage our app. When we were ready to make the switchover, we stopped Phusion Passenger, added our MongoDB connection string to our nginx config file, and then restarted Phusion Passenger.


CodeBuddies is a small project now, but we do not want to be unprepared when the community grows. We chose MongoDB Atlas for its mature performance monitoring tools, professional support, and easy scaling.

How Kustomer uses MongoDB and AWS to help fill in the gaps in the customer journey

Kustomer is a SaaS-based customer relationship platform designed to integrate conversations, transactions, and a company's proprietary data in one single system, capturing all aspects of the customer journey. We sat down with Jeremy Suriel, CTO & Co-Founder of Kustomer, to learn more.

Tell us about Kustomer

My co-founder and I worked together for 20 years in customer support. Over time, we’ve seen major changes in the industry - social media gave consumers a voice, users started communicating through text, mobile computing took off - and companies weren’t listening to their customers through these new channels.

Recognizing these changes, Kustomer was launched in 2015 as a CRM platform to improve the customer experience. Our goal is to help companies compile customer information into one place, automate business processes, address the pain points behind customer support systems, and enable users to make smarter, data driven decisions.

What are you building with MongoDB?

We are building an application that allows Kustomer users to get a complete picture of their customer’s activity from the first interaction through the entire journey. This insight allows customer support representatives to provide a better, more personalized experience to the end user. With Kustomer, users are able to combine conversations, custom objects, and track events in an easy-to-use interface. They are able to collect historical data behind every account from every channel, get insight into the customer sentiment, and more.

We could have chosen any data storage engine for this application. We briefly considered MySQL, Postgres, and DynamoDB, however, when compared to the alternatives, MongoDB was the stand out in two key areas. First, we needed to store complicated data in a simple way. MongoDB’s flexible data model allowed us to have independent tenants in our platform with the ability for each customer to define the structure of their data based on their specific requirements. Relational data stores didn’t give us this option and DynamoDB lacked some key features and flexibility like easily adding secondary compound indexes to an existing data model.

Second, we decided early on that we would be a JavaScript shop, specifically Node.js on the backend and React.js on the frontend. From a hiring perspective, we found that Node.js engineers have a lot of familiarity with MongoDB. Building our platform on MongoDB helps us get access to the top talent with the relevant set of expertise, and allow us to build our application quickly and efficiently.

We were also excited to leverage MongoDB’s WiredTiger storage engine with improved performance and concurrency. Overall, MongoDB was a no-brainer for us.

Please describe your application stack. What technologies or services are you using?

We have a microservice-based architecture with MongoDB as the primary database storing the majority of our data. Our infrastructure is running in AWS where we follow standard best practices.

  • Services are continuously deployed with zero-downtime from CircleCI to Amazon Elastic Container Service (ECS) running our docker-based microservice containers.
  • All services running with an AWS VPC, Multi-AZ for high availability with auto-scaling and traffic distributed through AWS ELB/ALBs.
  • API gateways sit in front of all our microservices, handling authentication, authorization, and auditing.
  • Customer Search & Segmentation, which is a core functionality of our platform, is powered by Elasticsearch.
  • We rely on AWS Kinesis Data Streams to collect and process events.
  • We use AWS Lambda functions to help customers populate AWS Redshift and create real-time dashboards. We’re also developing a Snowflake integration for other analytics use cases.
  • Finally, we use Terraform to automatically configure our cloud-based dev, qa, staging, and production environments.

We leverage MongoDB Enterprise Advanced for ongoing support and for the additional software that helps us with database operations. For example, we use the included Cloud Manager product to manage our database backups. The tool helps us upgrade our clusters, connect our alerts to Slack, and more. Our favorite feature of MongoDB Cloud Manager is the profiling/metrics dashboard that allows us to see everything that is happening within our deployment at all times and perform very specific queries to get greater insights into performance.

How is MongoDB performing for you?

MongoDB continues to perform well as our application and usage grows. We now have 1-4 millisecond reads and sub-millisecond writes. Our data volume has grown 80% since last quarter and we currently have 30+ MongoDB databases with well over 100 collections. We may explore sharding one or more of our services’ MongoDB collections and/or migrating to MongoDB Atlas in the future.

Overall we’ve experienced great benefits with MongoDB. We have great response times, are able to get the talent we need, are easily able to personalize our product to our customers’ needs, and more. Our company would not be where we are today if we had based our application on any other database.

SEGA HARDlight Migrates to MongoDB Atlas to Simplify Ops and Improve Experience for Millions of Mobile Gamers

It was way back in the summer of ‘91 that Sonic the Hedgehog first chased rings across our 2D screens. Gaming has come a long way since then. From a static TV and console setup in ‘91, to online PC gaming in the noughties and now to mobile and virtual reality. Surprisingly, for most of those 25 years, the underlying infrastructure that powered these games hasn’t really changed much at all. It was all relational databases. But with ever increasing need for scale, flexibility and creativity in games, that’s changing fast. SEGA HARDlight is leading this shift by adopting a DevOps culture and using MongoDB Atlas, the cloud hosted MongoDB service, to deliver the best possible gaming experience.

Bringing Icons to Mobile Games

SEGA HARDlight is a mobile development studio for SEGA, a gaming company you might have heard of. Based in the UK’s Royal Leamington Spa, SEGA HARDlight is well known for bringing the much-loved blue mascot Sonic the Hedgehog to the small screen. Along with a range of Sonic games, HARDlight is also responsible for building and running a number of other iconic titles such as Crazy Taxi: City Rush and Kingdom Conquest: Dark Empire.

Sonic Dash

Earlier versions of the mobile games such as Sonic Jump and Sonic Dash didn’t require a connection to the internet and had no server functionality. As they were relatively static games, developers initially supported the releases with an in-house tech stack based around Java and MySQL and hosted in SEGA HARDlight’s own data centre.

The standard practice for launching these games involved load testing the servers to the point of breaking, then provisioning the resources to handle an acceptable failure point. This limited application functionality, and could cause service outages when reaching the provisioned resources’ breaking point. As the games started to add more online functionality and increased in popularity, that traditional stack started to creak.

Massive Adoption: Spiky Traffic

Mobile games have an interesting load pattern. People flock in extreme numbers very soon after the release. For the most popular games, this can mean many millions people in just a few days or even hours. The peak is usually short and then quickly drops to a long tail of dedicated players. Provisioning for this kind of traffic with a dynamic game is a major headache. The graph from the Crazy Taxi: City Rush launch in 2014 demonstrates just how spiky the traffic can be.

Typical usage curve for a popular mobile game

We spoke with Yordan Gyurchev, Technical Director at SEGA HARDlight, who explained: “With these massive volumes even minor changes in the database have a big impact. To provide a perfect gaming experience developers need to be intimately familiar with the performance trade offs of the database they’re using,”

Crazy Taxi : City Rush

Supersonic Scaling

SEGA HARDlight knew that the games were only going to get more online functionality and generate even more massive bursts of user activity. Much of the gaming data was also account-based so it didn’t fit naturally in the rows and columns of relational databases. In order to address these limitations, the team searched for alternatives. After reviewing Cassandra and Couchbase, but feeling they were either too complex to manage or didn’t have the mature support needed to support the company’s SLAs, the HARDlight engineers looked to MongoDB Atlas, the MongoDB database as a service.

Then came extensive evaluations and testing across multiple dimensions such as cost, maintenance, monitoring and backups. It was well known that MongoDB natively had the scalability and flexibility to handle large volumes and always-on deployments but HARDlight’s team had to have support on the operations side too.

Advanced operational tooling in MongoDB Atlas gave a small DevOps team of just two staffers the ability to handle and run games even as millions of people join the fray. They no longer had to worry about maintenance, upgrades or backups. In fact, one of the clinchers was the point in time backup and restore feature which meant that they can roll back to a checkpoint with the click of a button. With MongoDB Atlas and running on AWS, SEGA HARDlight was ready to take on even Boss Level scaling.

“At HARDlight we’re passionate about finding the right tool for the job. For us we could see that using a horizontally scalable document database was a perfect fit for player-account based games,” said Yordan.

“The ability to create a high traffic volume, highly scalable solution is about knowing the tiny details. To do that, normally engineers need to focus on many different parts of the stack but MongoDB Atlas and MongoDB’s support gives us a considerable shortcut. If this was handled in-house we would only be as good as our database expert. Now we can rely on a wealth of knowledge, expertise and best in class technology.”

Sonic Forces

HARDlight’s first MongoDB powered game was Kingdom Conquest: Dark Empire which was a frictionless launch from the start and gave the engineers their first experiences of MongoDB. Then in a weekend in late 2017 Sonic Forces: Speed Battle was launched on mobile. It’s a demanding, always-on application that enables constant connection to the internet and shared leaderboards. In the background a 3 shard cluster running on MongoDB Atlas easily scaled to handle the complex loads as millions of gamers joined the race. The database was stable with low latencies and not a single service interruption. All of this resulted in a low stress launch, a happy DevOps team and a very enthusiastic set of gamers.

The latest SEGA HARDlight mobile game: Sonic Forces: Speed Battle

Yordan concluded: “With MySQL, it had taken multiple game launches to get the database backend right. With MongoDB Atlas, big launches were a success right from the start. That’s no mean feat.”

Just as the gaming platforms have evolved and transformed through the years, so too has the database layer had to grow and adapt. SEGA HARDlight is now expanding its use of MongoDB Atlas to support all new games as they come online. By taking care of the operations, management and scaling, MongoDB Atlas lets HARDlight focus on building and running some of the most iconic games in the world. And doing it with confidence.

Gone is the 90s infrastructure. Replaced by a stack that is every bit as modern, powerful and fast as the famous blue hedgehog.

SEGA Hardlight is looking for talented engineers to join the team. If you are interested, check out the careers page or email:

How uses MongoDB Atlas to Bring a Seamless Customer Experience to the Business Travel Market

As consumer travel apps like Expedia and Kayak are continuously innovating to provide more seamless booking experiences for their customers, their B2B counterparts can seem very outdated in comparison. Hamburg-based startup, is looking to change that.

We recently sat down with Voya’s CTO, Pepijn Schoen, to learn more about how they are using MongoDB alongside natural language processing and machine learning to bring B2B travel booking into 2018 with their chat-based app.

MongoDB: Tell me about Voya.

Pepijn Schoen: Voya is a purely digital, business travel app that brings the convenience and customer experience of B2C travel booking tools to the B2B market. We use a chat-based, conversational interface to interpret our users’ travel needs and extract the search parameters using natural language processing. We started the company in 2015 and after winning the Best Travel Technology Award in 2016, grew the company to a now 50-people team of travel experts, servicing 150 companies with their business travel needs.

What about the B2B travel booking market are you trying to disrupt?

Most of the tools businesses use today were created 10 to 20 years ago. Since then, companies like Expedia, Kayak, and have transformed our expectations of what a travel booking experience should be like. In addition, today’s business travel booking process includes many different layers of vendors. For example, a company may work with different vendors for flights, car rental, and hotels on top of vendors for expense management and for providing the search and booking front end. All of this creates unnecessary friction for the end user. Voya allows a direct, simple solution for business travelers to create itineraries that comply with company policies and expense processes.

Tell me about how Voya is using AI.

We use artificial intelligence in two primary ways. Firstly, we use natural language processing to interpret chat-based user inputs. For most requests, the entire booking experience can be handled this way, but we also have a mechanism to connect the user to a live agent for more complex requests.

Secondly, we have built a proprietary flight and hotel matching engine that considers a multitude of different parameters when recommending travel options to a user. For example, companies may have price or airline restrictions, users may have a preference for a certain rewards program, and nearly all business travellers prefer shorter, more direct routes over long layovers. Our matching engine considers these factors to suggest the best flights and hotels.

What tools and technologies are you using to make this possible?

Our NLP is powered by a Java-based application using Google Dialogflow and the Layer API for messaging. The rest of our stack includes AngularJS (including Angular 4 and 5), Python, .NET, MySQL, and MongoDB in AWS via MongoDB Atlas. We also use Kubernetes which makes our deployment very portable. For example, we can leverage Google technologies while keeping our primary datastores in AWS.

How are you using MongoDB?

We use MongoDB to store data about almost every one of the approximately 1.5 million hotels in the world. The support for GeoJSON was one of the key reasons we decided to build on MongoDB, and we feel it is the best option to power our geolocation searches. By storing hotel location and metadata in MongoDB, we can then let our users easily find matching properties by generating geospatial queries behind the scenes without custom application code.

There was a learning curve with this technology. For example, we had to troubleshoot a query that was dependent on a 2D index, rather than a more appropriate 2Dsphere index to take into consideration the fact that the Earth is not flat!

Currently, we query with a bounding box, but cities are never perfect squares and are therefore best approximated with polygons. We could definitely improve the accuracy of the data we get back from this type of query by using a more complex model.

Why did you decide to use MongoDB Atlas?

Originally, Voya was built on a single EC2 instance in AWS and we were running several other tools in a similar way. Rather than spread ourselves too thin building scalable, always-on, backed up clusters ourselves, we explicitly looked for managed service—MongoDB Atlas was a great fit.

The other advantage of building on MongoDB Atlas is that it allows us to expand globally without significant time investments from our team. Our application is currently available in English and German, with most of our users in Central Europe, so we minimize latency by running our MongoDB cluster in AWS’s Frankfurt region. As our user base expands, the ability to take advantage of multi-region replication to maintain this level of service will be incredibly valuable.

What’s next for Voya?

As a full-service travel solution, we are constantly looking at fulfilling our customer’s travel needs. To us, the fragmentation in business travel, with separate travel management companies and online bookings tools, didn't make sense. That's why we've unified them in one solution. To this, we're adding expense management. Travel expenses are a huge pain for many, wasting hours of travelers’ time tracking receipts manually and filling in forms in Excel for their accounting department. Technologically, this will bring another challenge for us, as we're trying to encode applicable local legislation (which can change annually) in MongoDB. For example, returning from a business trip to Copenhagen, Denmark, and continuing onwards to Bucharest the same day, requires precise understanding of the applicable allowances.

Additionally, we're continuously investing in artificial intelligence to decrease the turnaround time for travel requests. Our travel experts are there to help reroute you if you miss your New York - London flight, but we're working towards a state where all flight and hotel requests are completely automated.
