How much does MongoDB Atlas cost?
It is free to start with MongoDB Atlas for learning, prototyping, and early development. For dedicated clusters, MongoDB Atlas is billed hourly based on how much you use. The hourly rate depends on a number of factors, most importantly the size and number of servers you use. You will receive a single bill from MongoDB that explains your hourly use and backup fees.
For example, if you deploy on AWS a 3-node replica set of M40s and run it 24/7 for one month using the included 80GB of standard block storage, and you have exactly 80GB, your costs would be:
Per server hourly cost1: ~$0.34
Total servers: 3
Total hours: 720
Backup data: 80GB @ $2.50/GB/month
Total monthly fees paid to MongoDB: $946.79
What scale does MongoDB Atlas support?
MongoDB is one of the most scalable databases on the planet, and MongoDB Atlas brings you that same scalability, but with us managing it for you:
You can scale up or down on larger instance types with no application downtime
You can scale out across multiple instances with no application downtime using MongoDB’s native sharding capabilities
What MongoDB features does MongoDB Atlas not support?
Security cannot be disabled
Specialized replica set members: arbiters, hidden members, delayed secondaries
Reconfiguration of replica set member priority
Custom database roles
Advanced configuration options (eg, maxConns)
If these features are important to your deployment, consider MongoDB Cloud Manager to help you manage your customized configuration.
Can I move my existing MongoDB deployment to MongoDB Atlas?
You can easily move an deployment to MongoDB Atlas with minimal impact to your application using the live migration feature in the application. Live migration works by keeping a cluster in MongoDB Atlas in sync with your source database until you’re ready to cut over.
You can also move small to medium size data sets with relatively little downtime using mongodump/mongorestore.
Can you help me move my existing deployment to MongoDB Atlas?
Yes. We have a dedicated consulting package for this purpose. Whether your deployment is running on-prem, is self-managed in the cloud, or was provisioned by another MongoDB hosting provider, we can help you to take full advantage of the benefits of MongoDB Atlas. Learn more here.
What am I responsible for when using MongoDB Atlas?
MongoDB Atlas handles most of the management of your MongoDB deployment. You have the following responsibilities:
Query and index optimization
Server size selection - you must select the appropriate size of server, coupled with IO and storage capacity
Capacity planning - you must determine when you need additional capacity, typically using the monitoring telemetry provided by MongoDB Atlas, but you can make these changes with no downtime
Initiating database restores
Is MongoDB building data centers all over the world?
No, we are not building data centers.
Instead, MongoDB Atlas runs on different cloud platforms, such as Amazon Web Services, Microsoft Azure, and Google Cloud Platform, all of which provide extensive offerings in terms of data center location and SLAs. Initially we will support AWS, and are working to add support for other cloud platforms in the future.

What happens to my data if I want to leave MongoDB Atlas?
Because your data is continuously backed up, you can use MongoDB Atlas’s restore capabilities to generate a copy of your database for your own use, including seeding a new environment you manage yourself.
How does MongoDB Atlas assure high availability of my database?
Every MongoDB Atlas cluster is deployed as a self-healing replica set which provides automatic failover in the event of a failure. Replica set members are automatically provisioned by MongoDB Atlas across multiple availability zones (AWS), fault domains (Azure), or zones (GCP) within a region, providing resilience to localized site failures. For even better availability guarantees, cross-region replication can be enabled for any dedicated cluster, protecting you in the unlikely event of a cloud region failure.
How does MongoDB Atlas handle backups?
MongoDB Atlas continuously backs up your data, ensuring your backups are just a few seconds behind the operational system. The platform provides consistent, cluster-wide snapshots of sharded clusters. With continuous backup, you can restore to any point in time or query your snapshots to rapidly restore a subset of your data.
Continuous backups are charged separately from your MongoDB Atlas instances. Pricing ranges from $1.50 to $2.50 per GB/month, depending on snapshot frequency.
Cloud Provider Snapshots
MongoDB Atlas backs up your data using the native snapshot capabilities of the cloud provider. Your backups are stored in the same cloud region as your managed databases.
Currently, this option supports replica sets deployed in Amazon Web Services and Microsoft Azure.
Backups using cloud provider snapshots are charged separately from your MongoDB Atlas instances. Pricing varies by region.
How does MongoDB Atlas secure my data?
MongoDB Atlas is security hardened by default.
Each MongoDB Atlas group is provisioned into its own VPC, thus isolating your data and underlying systems from other MongoDB Atlas users. Network encryption and access control are configured by default, and IP whitelists allow you to specify a specific range of IP addresses against which access will be granted. All security-specific updates to the operating system and database of the underlying instances are automatically applied by MongoDB engineers.
For deployments running in AWS, VPC Peering can be used to connect your application servers deployed to another AWS VPC directly to your MongoDB Atlas cluster using private IP addresses.
All storage volumes on AWS, Azure, and GCP are automatically encrypted.
Enterprise Security features can be enabled for your MongoDB Atlas clusters. They include the following:
Database-level auditing: For regulatory compliance, security administrators can use MongoDB Atlas to retrieve audit logs tracking DML, DDL, and DCL operations taken against a managed cluster.
LDAP integration: Atlas offers integration with customer LDAP servers to simplify access control and granular permissions management for users and applications.
Bring your own key management service: Atlas supports the encrypted storage engine, a native encryption option for WiredTiger. With this option enabled, all database files are written to the filesystem encrypted and customers maintain control over the encryption keys for their fully managed clusters.
Read the MongoDB Atlas Security Controls white paper for more information about MongoDB Atlas security and data security.
Does MongoDB Atlas meet compliance standards that test for data safety, privacy, or security?
Service Organization Control (SOC) Reports are independent third-party examination reports that demonstrate how the MongoDB Atlas service achieves key compliance controls and objectives. The purpose of these reports is to help you and your auditors understand the controls established to support operations and compliance.
