MongoDB Atlas¶

What’s New in Atlas

Beta: Support for write operation through the Data Explorer.
Atlas live migration supports:
- Live Migrating a source sharded cluster running MongoDB 3.2, 3.4, or 3.6 to an Atlas sharded cluster running the same MongoDB version.
- Live Migrating a source replica set running MongoDB 2.6 or greater to an Atlas replica set.
(Azure only) Atlas now offers Cloud Provider Snapshots. Cloud provider snapshots are located in the same region as the corresponding cluster.
mongomirror supports mirroring from a source cluster running MongoDB 3.6.
Support for MongoDB 3.6 when creating or upgrading M10 or greater clusters.

MongoDB Stitch (Available in Beta)

MongoDB Stitch is a backend as a service that provides an HTTP API to MongoDB, integration with other services, and a declarative rules infrastructure which spans database and service actions.

Tutorial Series [Video]: Getting Started with MongoDB Atlas

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 3.2
MongoDB 3.4
MongoDB 3.6

M0 Free Tier and M2/M5 shared tier clusters only support MongoDB 3.4.

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.

Deployment¶

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

Security¶

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

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..
