MongoDB Atlas — the fully managed global cloud database — is the best way to deploy, operate, and scale MongoDB on Google Cloud Platform.
You can get started free with a sandbox environment that gives you 512 MB of storage for development and low-traffic applications.
The free M0 sandbox environment gives you —
A highly available replica set
Automated patches and improvements
Embedded Data Explorer to view and manipulate data during development
Built-in monitoring and alerting
Sandbox environments are available in 6 GCP regions, including Iowa, São Paulo, Belgium, Taiwan, Tokyo, and Singapore.
And when you need something more powerful for your workload — whether its more storage, dedicated RAM, backup & data recovery, or enterprise security features — you can deploy a dedicated Atlas cluster in any of the 20 Google Cloud regions.
