Reimagining Legacy Systems with AI: Why We're Building the Future
This article was adapted from an interview with Galileo’s Chain of Thought podcast. Watch the full episode on YouTube. At MongoDB, we talk a lot about what it means to be at an inflection point—a moment where you can either maintain the status quo or redefine what's possible. For my team and for software engineers around the world, that inflection point is here. Now. Large language models (LLMs), agents, and now model context protocol (MCP) are fundamentally changing not just how we work, but what is possible with technology. So we must adapt; we have to build differently, and be faster. At MongoDB, we're creating something unique. Something smarter. We’re embracing and exploring everything that AI can do for developers. And we’re inviting the next generation of engineers to join us in shaping it. The hidden cost of legacy systems If you've spent any time in enterprise engineering, you know the challenge many organizations face: decades-old systems that are critical to a company’s operations but are held together with duct tape and wishful thinking. The developers who built them have long since moved on. The documentation is missing, outdated, or was never written. The last update was six years ago; some of the dependencies are abandoned. Whether you call it “tech debt” or “care and feeding” or “maintenance”, it consumes a huge fraction of our time and engineering budget—without a clear path forward. This is the reality many companies face—whether they’re in finance , healthcare, or the public sector—they have no choice but to pour millions of dollars into just keeping these systems afloat. Or do they? At MongoDB, we're building a new kind of engineering capability—one that combines the latest advancements in generative AI with the principles of forward-deployed engineering to help modernize legacy systems at a speed and scale that feels impossible. What is forward-deployed AI engineering? Because it’s new, you may not have heard of this role before. It's a bridge between engineering, consulting, and product development. As an AI Forward Deployed Engineer, you won’t just sit behind the scenes writing code. You'll be embedded with our customers, working side by side with their teams to solve real-world modernization challenges. No theory, just hands-on engineering at the sharpest edge of AI innovation. Your goal? Write software with AI, write software for AI, at speeds you’ve never experienced. In some tasks, we have benchmarked AI as being more than eight hundred times faster than a human being… working in that environment is, I assure you, radically different. You’ll deliver immediate, meaningful impact—whether that’s untangling a million-line code base, modernizing outdated Java frameworks, or helping teams migrate from niche, unsupported languages to modern tech stacks. MongoDB + AI: Changing the game One of the most exciting parts of our work is how AI is fundamentally changing what's possible. In the past, a modernization project like this might take five years and dozens of engineers. Today, with the power of MongoDB and AI, that same work is done in a fraction of the time—sometimes in months, sometimes in weeks—with a much smaller, highly focused team. We use LLMs and other AI tools to do things like: Add missing documentation to legacy code Write unit tests where none existed Remove outdated frameworks, replacing them with others Analyze and map massive, messy code bases Move between programming languages, frameworks, platforms, ORMs, databases, and front-end technologies. Let me be clear—none of this is easy, or on autopilot. We augment great engineers with powerful tools so they can focus on the work that matters most, so they can think big, and go far . Combining human expertise with AI capability leads to outcomes no one thought possible. Why it matters Modernizing these systems isn’t just about efficiency or cost savings—it’s mission-critical. The legacy platforms power trading systems, healthcare infrastructure, and governmental services that support real people every day. In multiple countries around the world. Being able to show them a fully functional prototype in weeks, instead of years, is game-changing. It proves what's possible. It builds momentum. It allows them to rethink how they, too, can structure teams and processes in a world where technology moves faster than ever. Why join MongoDB? If you're an engineer who thrives on autonomy, problem-solving, and building real solutions with immediate impact—and you want to work with AI every day in novel and complex ways— this is your chance. We’re looking for folks from a variety of backgrounds—software development, consulting, product engineering, or technical architecture—who are passionate about learning and applying new technologies, skilled communicators who are excited to partner with customers, and who are comfortable operating in ambiguity. As part of our Application Modernization function, you will: Work directly with customers and stakeholders Rapidly build solutions that solve meaningful business challenges Operate at the intersection of engineering, product, and consulting Learn and apply cutting-edge AI, inventing both new methodologies and technologies Be part of a small, fast-moving, high-impact team You might even write a white paper or two. You’ll also be part of a culture that values leadership at every level. At MongoDB, we believe in making it matter —and this role is designed to make change, not just for our customers, but for the software industry as a whole. If you’ve ever wanted to be part of a startup within an enterprise, this is your opportunity. We're building a new way of working — one where experimentation, agility, and ownership are at the core.

Check out our open roles and join us in redefining what's possible.
Transforming News Into Audio Experiences with MongoDB and AI
You wake up, brew your coffee, and start your day with a perfectly tailored podcast summarizing the latest news—delivered in a natural, engaging voice. No manual curation, no human narration, just seamless AI magic. Sounds like the future? It's happening now, powered by MongoDB and generative AI. In 2025, the demand for audio content—particularly podcasts—surged, with 9 million new active listeners in the United States alone, prompting news organizations to seek efficient ways to deliver daily summaries to their audiences. However, automating news delivery has proven to be a challenging task, as media outlets must manage dynamic article data and convert this information into high-quality audio formats at scale. To overcome these hurdles, media organizations can use MongoDB for data storage alongside generative AI for podcast creation, developing a scalable solution for automated news broadcasting. This approach unlocks new AI-driven business opportunities and can attract new customers while strengthening the loyalty of existing ones, contributing to increased revenue streams for media outlets. Check out our AI Learning Hub to learn more about building AI-powered apps with MongoDB. The secret sauce: MongoDB + AI In a news automation solution, MongoDB acts as the system’s backbone, storing news article information as flexible documents with fields like title, content, and publication date—all within a single collection. Alongside this, dynamic elements (such as the number of qualified reads) can be seamlessly integrated into the same document to track content popularity. Moreover, derived insights—e.g., sentiment analysis and key entities—can be generated and enriched through a gen AI pipeline directly within the existing collection. Figure 1. MongoDB data storage for media. This adaptable data structure ensures that the system remains both efficient and scalable, regardless of content diversity or evolving features. As a result, media outlets have created a robust framework to query and extract the latest news and metadata from MongoDB. They can now integrate AI with advanced language models to transform this information into an audio podcast. With this foundation in place, let's examine why MongoDB is well-suited for implementing AI-driven applications. Why MongoDB is the perfect fit News data is inherently diverse, with each article containing a unique mix of attributes, including main content fields (e.g. id, title, body, date, imageURL), calculated meta data (e.g. read count), generated fields with the help of GenAI (e.g. keywords, sentiment) and embeddings for semantic/vector search. Some of these elements originate from publishers, while others emerge from user interactions or AI-driven analysis. MongoDB’s flexible document model accommodates all these attributes—whether predefined or dynamically generated, within a single, adaptable structure. This eliminates the rigidity of traditional databases and ensures that the system evolves seamlessly alongside the data it manages. What’s more, speed is critical in news automation. By storing complete, self-contained documents, MongoDB enables rapid retrieval and processing without the need for complex joins. This efficiency allows articles to be enriched, analyzed, and transformed into audio content in near real-time. And scalability is built in. Whether handling a small stream of updates or processing vast amounts of constantly changing data, MongoDB’s distributed architecture ensures high availability and seamless growth, making it ideal for large-scale media applications. Last but hardly least, developers benefit from MongoDB’s agility. Without the constraints of fixed schemas, new data points—whether from evolving AI models, audience engagement metrics, or editorial enhancements—can be integrated effortlessly. This flexibility allows teams to experiment, iterate, and scale without friction, ensuring that the system remains future-proof as news consumption evolves. Figure 2. MongoDB benefits for AI-driven applications. Bringing news to life with generative AI Selecting MongoDB for database storage is just the beginning; the real magic unfolds when text meets AI-powered speech synthesis. In our labs, we have experimented with Google’s NotebookLM model to refine news text, ensuring smooth narration with accurate intonation and pacing. Putting all these pieces together, the diagram below illustrates the workflow for automating AI-based news summaries into audio conversions. Figure 3. AI-based text-to-audio conversion architecture. The process begins with a script that retrieves relevant news articles from MongoDB, using the Aggregation Framework and Vector Search to ensure semantic relevance. These selected articles are then passed through an AI-powered pipeline, where they are condensed into a structured podcast script featuring multiple voices. Once the script is refined, advanced text-to-speech models transform it into high-quality audio, which is stored as a .wav file. To optimize delivery, the generated podcast is cached, ensuring seamless playback for users on demand. The result? A polished, human-like narration, ready for listeners in MP3 format. Thanks to this implementation, media outlets can finally let go of the robotic voices of past automations. Instead, they can now deliver a listening experience to their customers that's human, engaging, and professional. The future of AI-powered news consumption This system isn’t just a technological innovation; it’s a revolution in how we consume news. By combining MongoDB’s efficiency with AI’s creative capabilities, media organizations can deliver personalized, real-time news summaries without human intervention. It’s faster, smarter, and scalable—ushering in a new era of automated audio content. Want to build the next-gen AI-powered media platform? Start with MongoDB and let your content speak for itself!

Away From the Keyboard: Kyle Lai, Software Engineer 2
In “Away From the Keyboard,” MongoDB developers discuss what they do, how they keep a healthy work-life balance, and their advice for people seeking a more holistic approach to coding. In this article, Kyle Lai describes his role as a Software Engineer 2 at MongoDB; why he’d rather not be like the characters on the TV show, Severance; and how his commute helps set boundaries between his professional and personal lives. Q: What do you do at MongoDB? Kyle: Hi! I’m an engineer on Atlas Growth 1, where we run experiments on Atlas and coordinate closely with marketing, product, design, and analytics to improve the user experience. Atlas Growth 1 is part of the broader Atlas Growth engineering teams, where we own the experimentation platform and experiment software development kit, allowing other teams to run experiments as well! The engineers on Atlas Growth are very involved with the product side of our experiments. We help the analytics team collect metrics and decide if a given experiment was a win. Sometimes, seemingly obvious positive improvements can turn out to be detrimental to the user flow, so our experimentation process allows us to learn greatly about our users, whether the experiment wins or not. Q: What does work-life balance look like for you? Kyle: Work-life balance for me means that I won’t be worrying about responding to messages or needing to open my laptop after work hours. It also means that my teammates equally respect my work-life balance and do not expect me to work during non-work hours. Q: How do you ensure you set boundaries between work and personal life? Kyle: Generally, for me, it’s more difficult to set boundaries between work and personal life when I’m working from home, so I try to come into the office most days. My commute also provides me with time to wind down and signal that work is over for the day. In a way, the drive to and from the train station allows me to transition to getting into the mindset for work or to decompress at the end of the day. Q: Has work-life balance always been a priority for you, or did you develop it later in your career? Kyle: As someone who is early in my career, work-life balance is something that I’ve grown to appreciate and see as a priority in my life. It allows me to enjoy my personal life, and definitely contributes to a healthier me and a healthier team. Q: What benefits has this balance given you in your career? Kyle: Our team has a weekly Friday hangout meeting, where we have a different question posed to us each week. One of the questions was based on the TV show, Severance. Would we choose to be “severed” like the characters in the show? They undergo a procedure that separates their work and personal brains—their work brains have no awareness of their personal lives, and vice versa. As someone who hasn’t seen the show, but has heard about it from the rest of my team, I wouldn’t do it. Balancing my work and personal lives allows me to enjoy each side more. I’m motivated for the end of the week so I can enjoy the weekend, and I’m also excited to come to work with a fresh headspace on Mondays, since I am not overworking during non-work hours. Q: What advice would you give to someone seeking to find a better balance? Kyle: I’ll sometimes have the urge to continue working past work hours, as I’ll feel like I’m about to finish whatever task I’m working on very soon or think I can get even more done if I don’t stop working. That backfires pretty quickly. You have to realize you can be easily fatigued and are not able to give your best work if you constantly keep working. A proper work-life balance will allow you to have a fresh start and a clear mind each day. As for how to better separate work and personal life, I’d suggest changing notification settings on your phone for Slack, so that non-urgent work messages won’t tempt you to open your laptop. Another strategy would be to associate some event with a cutoff for checking work things, such as not reading messages once you’ve left the office or boarded the train. I’ve had teammates tell me they delete Slack from their phones when they’re on vacation, which is a good idea! Thank you to Kyle Lai for sharing these insights! And thanks to all of you for reading.

Unlocking BI Potential with DataGenie & MongoDB
Business intelligence (BI) plays a pivotal role in strategic decision-making. Enterprises collect massive amounts of data yet struggle to convert it into actionable insights. Conventional BI is reactive, constrained by predefined dashboards, and human-dependent, thus making it error-prone and non-scalable. Businesses today are data-rich but insight-poor. Enter DataGenie, powered by MongoDB—BI reimagined for the modern enterprise. DataGenie autonomously tracks millions of metrics across the entire business datascape. It learns complex trends like seasonality, discovers correlations & causations, detects issues & opportunities, connects the dots across related items, and delivers 5 to 10 prioritized actionable insights as stories in natural language to non-data-savvy business users. This enables business leaders to make bold, data-backed decisions without the need for manual data analysis. With advanced natural language capabilities through Talk to Data, users can query their data conversationally, making analytics truly accessible. The challenges: Why DataGenie needed a change DataGenie processes large volumes of enterprise data on a daily basis for customers, tracking billions of time series metrics and performing anomaly detection autonomously to generate deep, connected insights for business users. The below diagram represents the functional layers of DataGenie. Figure 1. DataGenie’s functional layers. Central to the capability of DataGenie is the metrics store, which stores, rolls up, and serves billions of metrics. At DataGenie, we were using an RDBMS (PostgreSQL) as the metrics store. As we scaled to larger enterprise customers, DataGenie processed significantly higher volumes of data. The complex feature sets we were building also required enormous flexibility and low latency in how we store & retrieve our metrics. DataGenie had multiple components that served different purposes, and all of these had to be scaled independently to meet our sub-second latency requirements. With PostgreSQL as the metrics store for quite some time and tried to squeeze it to the maximum extent possible at the cost of flexibility. Since we over-optimized the structure for performance, we lost the flexibility we required to build our next-gen features, which were extremely demanding We defaulted to PostgreSQL for storing the insights (i.e. stories), again optimized for storage and speed, hurting us on the flexibility part For the vector store, we had been using ChromaDB for storing all our vector embeddings. As the data volumes grew, the most challenging part was maintaining the data sync We had to use a different data store for knowledge store and yet another technology for caching The major problems we had were as follows: Rigid schema that hindered flexibility for evolving data needs. High latency & processing cost due to extensive preprocessing to achieve the desired structure Slow development cycles that hampered rapid innovation How MongoDB gave DataGenie a superpower After extensive experimentation with time-series databases, document databases, and vector stores, we realized that MongoDB would be the perfect fit for us since it exactly solved all our requirements with a single database. Figure 2. MongoDB data store architecture. Metrics store When we migrated to MongoDB, we achieved a remarkable reduction in query latency. Previously, complex queries on 120 million documents took around 3 seconds to execute. With MongoDB's efficient architecture, we brought this down to an impressive 350-500 milliseconds for 500M+ docs , representing an 85-90% improvement in query speed for a much larger scale. Additionally, for storing metrics, we transitioned to a key-value pair schema in MongoDB. This change allowed us to reduce our data volume significantly— from 300 million documents to just 10 million documents —thanks to MongoDB's flexible schema and optimized storage. This optimization not only reduced our storage footprint for metrics but also enhanced query efficiency. Insights store By leveraging MongoDB for the insight service, we eliminated the need for extensive post-processing, which previously consumed substantial computational resources. This resulted in a significant cost advantage, reducing our Spark processing costs by 90% or more (from $80 to $8 per job). Querying 10,000+ insights took a minute before. With MongoDB, the same task is now completed in under 6 seconds—a 10x improvement in performance . MongoDB’s flexible aggregation pipeline was instrumental in achieving these results. For example, we extensively use dynamic filter presets to control which insights are shown to which users, based on their role & authority. The MongoDB aggregation pipeline dynamically adapts to user configurations, retrieving only the data that’s relevant. LLM service & vector store The Genie+ feature in DataGenie is our LLM-powered application that unifies all DataGenie features through a conversational interface. We leverage MongoDB as a vector database to store KPI details, dimensions, and dimension values. Each vector document embeds essential metadata, facilitating fast and accurate retrieval for LLM-based queries. By serving as the vector store for DataGenie, MongoDB enables efficient semantic search, allowing the LLM to retrieve contextual, relevant KPIs, dimensions, and values with minimal latency, enhancing the accuracy and responsiveness of Genie+ interactions. Additionally, integrating MongoDB Atlas Search for semantic search significantly improved performance. It provided faster, more relevant results while minimizing integration challenges.MongoDB’s schema-less design and scalable architecture also streamlined data management. Knowledge store & cache MongoDB’s schema-less design enables us to store complex, dynamic relationships and scale them with ease. We also shifted to using MongoDB as our caching layer. Previously, having separate data stores made syncing and maintenance cumbersome. Centralizing this information in MongoDB simplified operations, enabled automatic syncing, and ensured consistent data availability across all features. With MongoDB, DataGenie is reducing time-to-market for feature releases Although we started the MongoDB migration to solve only our existing scalability and latency issues, we soon realized that just by migrating to MongoDB, we could imagine even bigger and more demanding features without engineering limitations. Figure 3. MongoDB + DataGenie integration. DataGenie engineering team refers v2 magic moment since migrating to MongoDB makes it a lot easier & flexible to roll out the following new features: DataGenie Nirvana: A delay in the supply chain for a raw material can cascade into a revenue impact. Conventional analytics relies on complex ETL pipelines and data marts to unify disparate data and deliver connected dashboard metrics. DataGenie Nirvana eliminates the need for a centralized data lake by independently generating aggregate metrics from each source and applying advanced correlation and causation algorithms on aggregated data to detect hidden connections. DataGenie Wisdom: Wisdom leverages an agentic framework & knowledge stores, to achieve two outcomes: Guided onboarding: Onboarding a new use case in DataGenie is as simple as explaining the business problem, success criteria, and sharing sample data - DataGenie autonomously configures itself for relevant metrics tracking to deliver the desired outcome. Next best action: DataGenie autonomously surfaces insights - like a 10% brand adoption spike in a specific market and customer demographics. By leveraging enterprise knowledge bases and domain-specific learning, DataGenie would propose targeted marketing campaigns as the Next Best Action for this insight. Powered by Genie: DataGenie offers powerful augmented analytics that can be quickly configured for any use case and integrated through secure, high-performance APIs. This powers data products in multiple verticals, including Healthcare & FinOps, to deliver compelling augmented analytics as a premium add-on, drastically reducing their engineering burden and GTM risk. All of these advanced features require enormous schema flexibility, low latency aggregation, and a vector database that’s always in sync with the metrics & insights. That’s exactly what we get with MongoDB! Powered by MongoDB Atlas, DataGenie delivers actionable insights to enterprises, helping them unlock new revenue potential and reduce costs. The following are some of the DataGenie use cases in Retail: Demand shifts & forecasting: Proactively adjust inventory or revise marketing strategies based on product demand changes. Promotional effectiveness: Optimize marketing spend by understanding which promotions resonate with which customer segments.

Introducing Database Digest: Building Foundations for Success
Today at MongoDB .local Toronto , I’m excited to share the first issue of Database Digest —MongoDB’s new digital magazine that explores the critical role of data in powering modern applications. This inaugural issue explores modern data architecture, and shows how—when the right data foundation meets emerging technologies—pioneering companies are fundamentally reimagining what's possible. The dawn of data ubiquity Currently, we stand in what McKinsey calls the " data ubiquity era "— with data flowing through organizations as essentially as electricity powers the modern world. The transformation to this era has brought both unprecedented opportunity and formidable challenges. Organizations must simultaneously manage huge volumes of data while delivering the real-time, personalized experiences that define competitive advantage today. Successfully doing so doesn’t mean merely adopting new technologies. Instead, it requires fundamentally rethinking how data is stored, processed, and leveraged to drive business value. Traditional relational database systems simply cannot meet these demands. The future belongs to organizations with data architectures designed for the agility, scalability, and versatility needed to handle diverse data types while seamlessly integrating with emerging technologies like AI. The cornerstone of AI success The rise of AI, and the speed at which the market has been changing have fundamentally shifted the importance of adaptability. However, software can only adapt as fast as its foundation allows. At MongoDB, we believe modern databases are the cornerstone of the age of AI, providing the essential capabilities needed for success in this new era. To do so, they must be able to: Handle all forms of data and provide intelligent search: Modern databases consolidate structured and unstructured data into a single system, eliminating silos that restrict AI innovation. They ground AI output in accurate, contextual data that drives better outcomes. Scale without constraints and react instantly: Databases should be able to adapt to unpredictable workloads and massive data volumes without performance degradation. They should enable real-time decisions and actions when opportunities or threats emerge. Embed domain-specific AI and secure data throughout: Modern databases enhance accuracy with specialized models that reduce hallucinations, and they protect information at every stage without sacrificing speed or functionality. Figure 1. Modern database demands. The impact of a modern database on AI innovation isn’t theoretical—we're seeing organizations like Swisscom leverage this approach to apply generative AI to their extensive expert content library, transforming how they serve the banking industry by delivering bespoke, contextual information within seconds. The AI revolution Perhaps nowhere is the impact of a modern data foundation more profound than in the rapid evolution of AI applications. In just a short time, we've progressed from simple LLM-powered chatbots to more advanced agentic systems capable of understanding complex goals, breaking them into manageable steps, and executing them autonomously—all while maintaining context and learning from interactions. This represents more than incremental progress—it's a fundamental shift in how AI serves as a strategic partner in solving business challenges. MongoDB sits at the heart of this transformation, providing the critical bridge between AI models and data while enabling vector storage, real-time processing, and seamless integration with LLM orchestrators. Companies like Questflow demonstrate the power of this approach, revolutionizing the future of work through a decentralized, autonomous AI agent network that orchestrates multiple AI agents collaborating with humans. By leveraging MongoDB's flexible document model and vector search capabilities, they're enabling startups to create dynamic AI solutions that handle everything from data analysis to content creation, while maintaining context and learning from interactions. Modernizing legacy systems: the strategic imperative For established enterprises, the journey to a modern data foundation often begins with addressing the legacy systems that consume up to 80% of IT budgets yet constrain innovation. Modernization isn't just a technical upgrade—it's a strategic move toward growth, efficiency, and competitive advantage. The evidence is compelling: Bendigo and Adelaide Bank achieved a staggering 90% reduction in both time and cost modernizing core banking applications using MongoDB's repeatable modernization framework and AI-powered migration tools. This transformation isn't just about cost savings—it's about creating the foundation for entirely new capabilities that drive business value. Modern data architecture must embody flexibility across multiple dimensions—from supporting diverse data models to providing deployment options spanning cloud-native, cloud-agnostic, and on-premise environments. This approach enables organizations to break free from silos, integrate AI capabilities, and create a unified data foundation supporting both current operations and future innovations. What’s next for data The organizations featured throughout Database Digest share a common vision: they recognize that tomorrow's success depends on today's data foundation. The convergence of flexible document models, advanced AI integration, and cloud-native capabilities isn't just enabling incremental improvements—it's powering applications and experiences that were never before possible. So I invite you to explore the full, inaugural issue of Database Digest to discover how MongoDB is helping organizations across industries build the foundation for tomorrow's success. This isn't just about technology—it's about creating the foundation for transformation that delivers real business value in our increasingly data-driven world.

Now Generally Available: 7 New Resource Policies to Strengthen Atlas Security
Organizations demand for a scalable means to enforce security and governance controls across their database deployments without slowing down developer productivity. To address this, MongoDB introduced resource policies in public preview on February 10th, 2025. Resource policies enable organization administrators to set up automated, organization-wide ‘guardrails’ for their MongoDB Atlas deployments. At public preview, three policies were released to this end. Today, MongoDB is announcing the general availability of resource policies in MongoDB Atlas. This release introduces seven additional policies and a new graphical user interface (GUI) for creating and managing policies. These enhancements give organizations greater control over MongoDB Atlas configurations, simplifying security and compliance automation. How resource policies enable secure innovation Innovation is essential for organizations to maintain competitiveness in a rapidly evolving global landscape. Companies with higher levels of innovation outperformed their peers financially, according to a Cornell University study analyzing S&P 500 companies between 1998 and 2023 1 . One of the most effective ways to drive innovation is by equipping developers with the right tools and giving them the autonomy to put them into action 2 . However, without standardized controls governing those tools, developers can inadvertently configure Atlas clusters to deviate from corporate or regulatory best practices. Manual approval processes for every new project create delays. Concurrently, platform teams struggle to enforce consistent security policies across the organization, leading to increased complexity and costs. As cybersecurity threats evolve daily and regulations tighten, granting developers autonomy and quickly provisioning access to essential tools can introduce risks. Organizations must implement strong security measures to maintain compliance and enable secure innovation. Resource policies empower organizations to enforce security and compliance standards across their entire Atlas environment. Instead of targeting specific user groups, these policies establish organization-wide guardrails to govern how Atlas can be configured. This reduces the risk of misconfigurations and security gaps. With resource policies, security and compliance standards are applied automatically across all Atlas projects and clusters. This eliminates the need for manual approvals. Developers gain self-service access to the resources they need while remaining within approved organizational boundaries. Simultaneously, platform teams can centrally manage resource policies to ensure consistency and free up time for strategic initiatives. Resource policies strengthen security, streamline operations, and help accelerate innovation by automating guardrails and simplifying governance. Organizations can scale securely while empowering developers to move faster without compromising compliance. What resource policies are available? table, th, td { border: 1px solid black; } Policy Type Description Available Since Restrict cloud provider Ensure clusters are only deployed on approved cloud providers (AWS, Azure, or Google Cloud).

GraphRAG with MongoDB Atlas: Integrating Knowledge Graphs with LLMs
A key challenge AI developers face is providing context to large language models (LLMs) to build reliable AI-enhanced applications; retrieval-augmented generation (RAG) is widely used to tackle this challenge. While vector-based RAG, the standard (or baseline) implementation of retrieval-augmented generation, is useful for many use cases, it is limited in providing LLMs with reasoning capabilities that can understand relationships between diverse concepts scattered throughout large knowledge bases. As a result, the accuracy of vector RAG-enhanced LLM outputs in applications can disappoint—and even mislead—end users. Now generally available, MongoDB Atlas ’ new LangChain integration for GraphRAG—a variation of RAG architecture that integrates a knowledge graph with LLMs—can help address these limitations. GraphRAG: Connecting the dots First, a short explanation of knowledge graphs: a knowledge graph is a structured representation of information in which entities (such as people, organizations, or concepts) are connected by relationships. Knowledge graphs work like maps, and show how different pieces of information relate to each other. This structure helps computers understand connections between facts, answer complex questions, and find relevant information more easily. Traditional RAG applications split knowledge data into chunks, vectorize them into embeddings, and then retrieve chunks of data through semantic similarity search; GraphRAG builds on this approach. But instead of treating each document or chunk as an isolated piece of information, GraphRAG considers how different pieces of knowledge are connected and relate to each other through a knowledge graph. Figure 1. Embedding-based vector search vs. entity-based graph search. GraphRAG improves RAG architectures in three ways: First, GraphRAG can improve response accuracy . Integrating knowledge graphs into the retrieval component of RAG has shown significant improvements in multiple publications. For example, benchmarks in the AWS investigation, “ Improving Retrieval Augmented Generation Accuracy with GraphRAG ” demonstrated nearly double the correct answers compared to traditional embedding-based RAG. Also, embedding-based methods rely on numerical vectors and can make it difficult to interpret why certain chunks are related. Conversely, a graph-based approach provides a visual and auditable representation of document relationships. Consequently, GraphRAG offers more explainability and transparency into retrieved information for improved insight into why certain data is being retrieved. These insights can help optimize data retrieval patterns to improve accuracy. Finally, GraphRAG can help answer questions that RAG is not well-suited for—particularly when understanding a knowledge base's structure, hierarchy, and links is essential . Vector-based RAG struggles in these cases because breaking documents into chunks loses the big picture. For example, prompts like “What are the themes covered in the 2025 strategic plan?” are not well handled. This is because the semantic similarity between the prompt, with keywords like “themes,” and the actual themes in the document may be weak, especially if they are scattered across different sections. Another example prompt like, “What is John Doe’s role in ACME’s renewable energy projects?” presents challenges because if the relationships between the person, the company, and the related projects are mentioned in different places, it becomes difficult to provide accurate responses with vector-based RAG. Traditional vector-based RAG can struggle in cases like these because it relies solely on semantic similarity search. The logical connections between different entities—such as contract clauses, legal precedents, financial indicators, and market conditions—are often complex and lack semantic keyword overlap. Making logical connections across entities is often referred to as multi-hop retrieval or reasoning in GraphRAG. However, GraphRAG has its own limitations, and is use-case dependent to achieve better accuracy than vector-based RAG: It introduces an extra step: creating the knowledge graph using LLMs to extract entities and relationships. Maintaining and updating the graph as new data arrives becomes an ongoing operational burden. Unlike vector-based RAG, which requires embedding and indexing—a relatively lightweight and fast process—GraphRAG depends on a large LLM to accurately understand, map complex relationships, and integrate them into the existing graph. The added complexity of graph traversal can lead to response latency and scalability challenges as the knowledge base grows. Latency is closely tied to the depth of traversal and the chosen retrieval strategy, both of which must align with the specific requirements of the application. GraphRAG introduces additional retrieval options . While this allows developers more flexibility in the implementation, it also adds complexity. The additional retrieval options include keyword and entity-based retrieval, semantic similarity on the first node, and more. MongoDB Atlas: A unified database for operational data, vectors, and graphs MongoDB Atlas is perfectly suited as a unified database for documents, vectors, and graphs. As a unified platform, it’s ideal for powering LLM-based applications with vector-based or graph-based RAG. Indeed, adopting MongoDB Atlas eliminates the need for point or bolt-on solutions for vector or graph functionality, which often introduce unnecessary complexity, such as data synchronization challenges that can lead to increased latency and potential errors. The unified approach offered by MongoDB Atlas simplifies the architecture and reduces operational overhead, but most importantly, it greatly simplifies the development experience. In practice, this means you can leverage MongoDB Atlas' document model to store rich application data, use vector indexes for similarity search, and model relationships using document references for graph-like structures. Implementing GraphRAG with MongoDB Atlas and LangChain Starting from version 0.5.0, the langchain-mongodb package introduces a new class to simplify the implementation of a GraphRAG architecture. Figure 2. GraphRAG architecture with MongoDB Atlas and LangChain First, it enables the automatic creation of a knowledge graph. Under the hood, it uses a specific prompt sent to an LLM of your choice to extract entities and relationships, structuring the data to be stored as a graph in MongoDB Atlas. Then, it sends a query to the LLM to extract entities and then searches within the graph to find connected entities, their relationships, and associated data. This information, along with the original query, then goes back to the LLM to generate an accurate final response. MongoDB Atlas’ integration in LangChain for GraphRAG follows an entity-based graph approach. However, you can also develop and implement your own GraphRAG with a hybrid approach using MongoDB drivers and MongoDB Atlas’ rich search and aggregation capabilities. Enhancing knowledge retrieval with GraphRAG GraphRAG complements traditional RAG methods by enabling deeper understanding of complex, hierarchical relationships, supporting effective information aggregation and multi-hop reasoning. Hybrid approaches that combine GraphRAG with embedding-based vector search further enhance knowledge retrieval, making them especially effective for advanced RAG and agentic systems. MongoDB Atlas’ unified database simplifies RAG implementation and its variants, including GraphRAG and other hybrid approaches, by supporting documents, vectors, and graph representations in a unified data model that can seamlessly scale from prototype to production. With robust retrieval capabilities ranging from full-text and semantic search to graph search, MongoDB Atlas provides a comprehensive solution for building AI applications. And its integration with proven developer frameworks like LangChain accelerates the development experience—enabling AI developers to build more advanced and efficient retrieval-augmented generation systems that underpin AI applications.

Next-Generation Mobility Solutions with Agentic AI and MongoDB Atlas
Driven by advancements in vehicle connectivity, autonomous systems, and electrification, the automotive and mobility industry is currently undergoing a significant transformation. Vehicles today are sophisticated machines, computers on wheels, that generate massive amounts of data, driving demand for connected and electric vehicles. Automotive players are embracing artificial intelligence (AI), battery electrical vehicles (BEVs), and software-defined vehicles (SDVs) to maintain their competitive advantage. However, managing fleets of connected vehicles can be a challenge. As cars get more sophisticated and are increasingly integrated with internal and external systems, the volume of data they produce and receive greatly increases. This data needs to be stored, transferred, and consumed by various downstream applications to unlock new business opportunities. This will only grow: the global fleet management market is projected to reach $65.7 billion by 2030, growing at a rate of almost 10.8% annually. A 2024 study conducted by Webfleet showed that 32% of fleet managers believe AI and machine learning will significantly impact fleet operations in the coming years; optimizing route planning and improving driver safety are the two most commonly cited use cases. As fleet management software providers continue to invest in AI, the integration of agentic AI can significantly help with things like route optimization and driver safety enhancement. For example, AI agents can process real-time traffic updates and weather conditions to dynamically adjust routes, ensuring timely deliveries while advising drivers on their car condition. This proactive approach contrasts with traditional reactive methods, improving vehicle utilization and reducing operational and maintenance costs. But what are agents? In short, they are operational applications that attempt to achieve goals by observing the world and acting upon it using the data and tools the application has at its disposal. The term "agentic" denotes having agency, as AI agents can proactively take steps to achieve objectives without constant human oversight. For example, rather than just reporting an anomaly based on telemetry data analysis, an agent for a connected fleet could autonomously cross-check that anomaly against known issues, decide whether it's critical or not, and schedule a maintenance appointment all on its own. Why MongoDB for agentic AI Agentic AI applications are dynamic by nature as they require the ability to create a chain of thought, use external tools, and maintain context across their entire workflow. These applications generate and consume diverse data types, including structured and unstructured data. MongoDB’s flexible document model is uniquely suited to handle both structured and unstructured data as vectors. It allows all of an agent’s context, chain-of-thought, tools metadata, and short-term and long-term memory to be stored in a single database. This means that developers can spend more time on innovation and rapidly iterate on agent designs without being constrained by rigid schemas of a legacy relational database. Figure 1. Major components of an AI agent. Figure 1 shows the major components of an AI agent. The agent will first receive a task from a human or via an automated trigger, and will then use a large language model (LLM) to generate a chain of thought or follow a predetermined workflow. The agent will use various tools and models during its run and store/retrieve data from a memory provider like MongoDB Atlas . Tools: The agent utilizes tools to interact with the environment. This can contain API methods, database queries, vector search, RAG application, anything to support the model Models: can be a large language model (LLM), vision language model (VLM), or a simple supervised machine learning model. Models can be general purpose or specialized, and agents may use more than one. Data: An agent requires different types of data to function. MongoDB’s document model allows you to easily model all of this data in one single database. An agentic AI spans a wide range of functional tools and context. The underlying data structures evolve throughout the agentic workflow and as an agent uses different tools to complete a task. It also builds up memory over time. Let us list down the typical data types you will find in an agentic AI application. Data types: Agent profile: This contains the identity of the agent. It includes instructions, goals and constraints. Short-term memory: This holds temporary, contextual information—recent data inputs or ongoing interactions—that the agent uses in real-time. For example, short-term memory could store sensor data from the last few hours of vehicle activity. In certain agentic AI frameworks like Langgraph, short term memory is implemented through a checkpointer. The checkpointer stores intermediate states of the agent’s actions and/or reasoning. This memory allows the agent to seamlessly pause and resume operations. Long-term memory: This is where the agent stores accumulated knowledge over time. This may include patterns, trends, logs and historical recommendations and decisions. By storing each of these data types into rich, nested documents in MongoDB, AI developers can create a single-view representation of an agent’s state and behavior. This enables fast retrieval and simplifies development. In addition to the document model advantage, building agentic AI solutions for mobility requires a robust data infrastructure. MongoDB Atlas offers several key advantages that make it an ideal foundation for these AI-driven architectures. These include: Scalability and flexibility: Connected Car platforms like fleet management systems need to handle extreme data volumes and variety. MongoDB Atlas is proven to scale horizontally across cloud clusters, letting you ingest millions of telemetry events per minute and store terabytes of telemetry data with ease. For example, the German company ZF uses MongoDB to process 90,000 vehicle messages per minute (over 50 GB of data per day) from hundreds of thousands of connected cars. The flexibility of the document model accelerates development and ensures your data model stays aligned with the real-world entities it represents. Built-in vector search: AI agents require a robust set of tools to work with. One of the most widely used tools is vector search, which allows agents to perform semantic searches on unstructured data like driver logs, error codes descriptions, and repair manuals. MongoDB Atlas Vector Search allows you to store and index high-dimensional vectors alongside your documents and to perform semantic search over unstructured data. In practice, this means your AI embeddings live right next to the relevant vehicle telemetry and operational data in the database, simplifying architectures for use cases like the connected car incident advisor, in which a new issue can be matched against past issues before passing contextual information to the LLM. For more, check out this example of how an automotive OEM leverages vector search for audio based diagnostics with MongoDB Atlas Vector Search. Time series collections and real-time data processing: MongoDB Atlas is designed for real-time applications. It provides time series collections for connected car telemetry data storage, change streams, and triggers that can react to new data instantly. This is crucial for agentic AI feedback loops, where ongoing data ingestion and learning are happening continuously. Best-in-class embedding models with Voyage AI: In early 2025, MongoDB acquired Voyage AI , a leader in embedding and reranking models. Voyage AI embedding models are currently being integrated into MongoDB Atlas, which means developers will no longer need to manage external embedding APIs, standalone vector stores, or complex search pipelines. AI retrieval will be built into the database itself, making semantic search, vector retrieval, and ranking as seamless as traditional queries. This will reduce the time required for developing agentic AI applications. Agentic AI in action: Connected fleet incident advisor Figure 2 shows a list of use cases in the Mobility sector, sorted by various capabilities that an agent might demonstrate. AI agents excel at managing multi-step tasks via context management across tasks, they automate repetitive tasks better than Robotic process automation (RPA), and they demonstrate human-like reasoning by revisiting and revising past decisions. These capabilities enable a wide range of applications both during the manufacturing of a vehicle and while it's on the road, connected and sending telemetry. We will review a use case in detail below, and will see how it can be implemented using MongoDB Atlas, LangGraph, Open AI, and Voyage AI. Figure 2. Major use cases of agentic AI in the mobility and manufacturing sectors. First, the AI agent connects to traditional fleet management software and supports the fleet manager in diagnosing and advising the drivers. This is an example of a multi-step diagnostic workflow that gets triggered when a driver submits a complaint about the vehicle's performance (for example, increased fuel consumption). Figure 3 shows the sequence diagram of the agent. Upon receiving the driver complaint, it creates a chain of thought that follows a multi-step diagnostic workflow where the system ingests vehicle data such as engine codes and sensor readings, generates embeddings using the Voyage AI voyage-3-large embedding model, and performs a vector search using MongoDB Atlas to find similar past incidents. Once relevant cases are identified, those–along with selected telemetry data–are passed to OpenAI gpt-4o LLM to generate a final recommendation for the driver (for example, to pull off immediately or to keep driving and schedule regular maintenance). All data, including telemetry, past issues, session logs, agent profiles, and recommendations are stored in MongoDB Atlas, ensuring traceability and the ability to refine diagnostics over time. Additionally, MongoDB Atlas is used as a checkpointer by LangGraph, which defines the agent's workflow. Figure 3. Sequence diagram for a connected fleet advisor agentic workflow. Figure 4 shows the agent in action, from receiving an issue to generating a recommendation. So by leveraging MongoDB’s flexible data model and powerful Vector Search capabilities, we can agentic AI can transform fleet management through predictive maintenance and proactive decision-making.
