Infrastructure provisioning, setup, and deployment is fully automated with MongoDB Atlas. Select a cloud provider, region, instance size, memory, and additional configurations in the Cluster Builder or via the API and be on your way.
When requirements and workloads change, MongoDB Atlas makes it easy to make post-deployment modifications to the database. Scale up, add more storage, configure cross-region clusters, create read-only or analytics nodes, and more with the click of a button.
Patches and minor version upgrades are applied automatically so you can take advantage of the latest updates and features. For major version upgrades, you choose when you want them to happen. Atlas makes it easy to spin up environments to test compatibility or try out new features.
After you deploy a new cluster in MongoDB Atlas, the Live Migration Service makes a copy of the data from your source database. Your application can continue to read and write from the source database, with any changes syncing to the new cluster until you’re ready to cut over. To complete the migration, change the connection string in your application from your source database to your Atlas cluster.
