You can store your data with Amazon Web Services (AWS), Google Cloud Platform, or Microsoft Azure. However, you don’t need to set up an account with any of these platforms. MongoDB Atlas takes care of all this behind the scenes.

MongoDB Atlas also automatically handles backend administrative processes such as provisioning resources, setting up clusters, or scaling services. Most of the tasks you perform are simple point-and-click operations that you carry out through the service’s centralized web interface.

What is included in the MongoDB Atlas free cluster?

No introduction to MongoDB Atlas is complete without mentioning its free M0 tier, which includes:

  • 512 MB of storage
  • Shared RAM
  • Highly available replica sets, end-to-end encryption, automated patches, REST API
  • Max connections: 100
  • Network performance: Low
  • Max databases: 100

The free tier cluster regions available are:
