MongoDB Atlas

Service Advisory for MongoDB 3.2

MongoDB Server 3.2 is planned for End of Life on September 2018. Atlas deprecated support for deploying clusters with MongoDB 3.2 in March, 2018.

Atlas will automatically upgrade any clusters running MongoDB 3.2 to MongoDB 3.4 in September 2018. Project Owners can upgrade their MongoDB 3.2 clusters at any time before then.

See I have a cluster running MongoDB 3.2. How does the upcoming End of Life affect me? for guidance on how to manage Atlas clusters currently running MongoDB 3.2.

What’s New in Atlas

  • Release mongomirror 0.4.0, which includes support for MongoDB 4.0 on both the source and destination cluster.

  • Support for deploying Atlas clusters in the Google Cloud Platform Montréal, Canada and Eemshaven, Netherlands regions.

  • Support for deploying M10+ clusters with MongoDB 4.0.

  • Support for LDAP User Authentication and Authorization and Encryption at Rest via customer KMS Advanced Security for Atlas projects and clusters.

  • Support for deploying Global Clusters. Global Clusters support location-aware read and write operations for globally distributed application instances and clients.

  • Support for deploying M0/M2/M5 clusters in additional Amazon Web Services and Google Cloud Platform regions:

    Cloud Provider Region M0 M2/M5
    AWS Singapore check square icon check square icon
    AWS Mumbai check square icon check square icon
    GCP US Central check square icon check square icon
    GCP Belgium check square icon check square icon
    GCP Singapore check square icon  
  • Support for Cloud Provider Snapshots of Amazon Web Services and Azure backed replica sets .

MongoDB Atlas is a cloud service for running, monitoring, and maintaining MongoDB deployments, including the provisioning of dedicated servers for the MongoDB instances. In addition, Atlas provides the ability to introspect collections, query backups, and migrate data from existing MongoDB replica set into an Atlas cluster.

MongoDB Deployments

MongoDB deployments, or “clusters” in Atlas, can be either a replica set or a sharded cluster.

MongoDB Versions

Atlas supports creating M10+ paid tier clusters with the following MongoDB versions:

  • MongoDB 3.4
  • MongoDB 3.6
  • MongoDB 4.0

MongoDB Server 3.2 is planned for End of Life on September 2018. Atlas deprecated support for deploying clusters with MongoDB 3.2 in March, 2018.

M0 Free Tier and M2/M5 shared tier clusters built after April 23, 2018 only support MongoDB 3.6.

As new maintenance releases become available, Atlas automatically upgrades to these releases via a rolling process to maintain cluster availability.

If the workload on the Atlas cluster is such that it impedes operations, including the ability to scale, MongoDB Atlas may, in some situations, create indexes in your cluster as a safeguard.


Atlas deploys each mongod process to its own instance. For sharded clusters, the mongos routers (the processes) run on each of the shard servers; i.e. each of the mongos processes shares an instance with one mongod process.

Depending on the cloud provider and region selected for the Atlas project, Atlas distributes each cluster across the region for high availability. For more information on how Atlas manages cluster distribution, see Amazon Availability Zones for AWS, GCP Zones for GCP, and Azure Fault Domains for Azure.

Atlas deploys each cluster with mandatory security.

Atlas Organization and Project

Atlas provides an organizations and projects hierarchy to facilitate the management of your Atlas clusters. In the organizations and projects hierarchy, an organization can contain multiple projects (previously referred to as groups).

Your Atlas project manages your MongoDB deployments. An Atlas project can have multiple MongoDB clusters.

For more information, see Organizations and Projects.


Atlas secures your deployments through the use of Transport Layer Security, virtual private cloud (VPC) subnet with IP whitelists, and user authentication and authorization.

TLS 1.0 Deprecation Warning

As of the end of July 2018, new MongoDB Atlas clusters have TLS 1.0 disabled by default. In late August 2018, Atlas will disable TLS 1.0 on all Atlas clusters. Atlas supports TLS 1.1 and 1.2 on all Atlas clusters.

To learn more about TLS 1.0 deprecation, see What versions of TLS does Atlas support?.


Atlas provides support for the use of the service itself. Support for development and performance of the database itself requires a MongoDB subscription. For details, contact MongoDB Inc..
