Use these resources to choose and create clusters and serverless instances.
MongoDB Atlas can deploy two types of cloud databases: serverless instances and clusters. You can use both clusters and serverless instances in the same Atlas project.
Create a cluster if you want to:
- Choose a specific database configuration based on your workload requirements.
- Define database scaling behavior.
- Run high-throughput production workloads.
- Always have capacity available.
- Set the cluster tier.
- Use advanced capabilities such as sharding.
- Distribute your data to multiple regions and cloud providers.
- Scale your cluster on-demand.
- Enable autoscaling. Unlike serverless instances, autoscaling for clusters requires preconfiguration.
MongoDB bills clusters based on the deployment configuration and cluster tier.
Create a serverless instance if you want to:
- Get started quickly with minimal database configuration.
- Have your database scale automatically and dynamically to meet your workload.
- Run infrequent or sparse workloads.
- Develop or test in a cloud environment.
Atlas automatically scales the storage capacity, storage throughput, and computing power for a serverless instance seamlessly to meet your workload requirements. Serverless instances always run the latest MongoDB version, and you only pay for the operations that you run.
Create a global cluster if you want to support location-aware read and write operations. Location-aware read and write operations are ideal for globally-distributed application instances and clients.
Global Clusters are a highly-curated implementation of a sharded cluster that offer:
- Low-latency read and write operations for globally distributed clients.
- Uptime protection during partial or full regional outages.
- Location-aware data storage in specific geographic regions.
- Workload isolation based on cluster member types.
You can enable Global Writes in Atlas when deploying an
greater sharded cluster. For replica sets,
scale the cluster to at least an
tier and enable Global Writes. All shard nodes deploy with the
You can't disable Global Writes for a cluster once it is deployed.
The following table indicates whether clusters or serverless instances support the listed configuration or capability in MongoDB Atlas.
Google Cloud regions
Microsoft Azure regions
Use the Atlas API
Configure alerts on available metrics or billing
Perform point-in-time or automated restores from backup snapshots
Use the Atlas UI (Find, Indexes, Schema Advisor and Aggregation Pipeline Builder)
Use Atlas Search
Use Online Archive
Use BI Connector
Use MongoDB Charts
You can’t migrate into clusters from serverless instances.
