Question

How AWS RDS ensure high availability and reliability?

Answer 1

AWS RDS allows multi-AZ deployment to ensure high availability and reliability.

1. With the use of multi-AZ deployment feature, AWS automatically provisions and maintains a synchronous standby replica in a different Availability Zone.
2. AWS synchronously replicates the data from the primary to the secondary database instance.
3. Failover Support: In case if the primary database instance fails or gets shut down in any way, AWS will automatically fail over to another secondary database instance.
