What is the best practice for creating a highly available PostgreSQL database in RDS that can sustain the loss of a single AWS region?

Question

Accepted Answer

Create Read Replicas in other AWS regions. Ensure read operations against the database occur on an available Read Replica, and send write operations to another region if you need to promote a Read Replica to a standalone database if the master is down.

Answer

Create Read Replicas in other AWS regions. You can designate a new master database from any of the read replicas until the regional failure is resolved.

Answer

Verify that your instance is configured for Multi-AZ support. Database changes will be automatically synced to another region in the event of a failure and RDS will automatically select a new master until the regional failure is resolved.

Answer

PostgreSQL cannot be replicated across regions. Restore the database backups from an S3 bucket and repoint your database connections to the new instance.
