MongoDB Atlas is a cloud service for running, monitoring, and maintaining MongoDB deployments, including the provisioning of dedicated servers for the MongoDB instances.
Atlas supports MongoDB 3.2 and MongoDB 3.4 with the WiredTiger storage engine. By default, Atlas uses MongoDB 3.4. You can specify the MongoDB version when you create a cluster. If a created cluster uses MongoDB 3.2, you can upgrade to MongoDB 3.4 when you scale a cluster.
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.

Your Atlas group manages your MongoDB deployments. An Atlas group can have multiple MongoDB clusters.
A unique AWS Virtual Private Cloud (VPC) is created for each Atlas group. All clusters for the group are deployed inside this VPC. This region-specific VPC is created for the Atlas group during the deployment of the group’s first cluster.
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..
