RDS Multi-AZ Deployments

  • RDS Multi-AZ deployments provide enhanced availability and durability for RDS database (DB) instances, making them a natural fit for production database workloads.

  • When you provision a Multi-AZ DB Instance, RDS automatically creates a primary DB Instance and synchronously replicates the data to a standby instance in a different Availability Zone (AZ).

  • Each AZ runs on its own physically distinct, independent infrastructure, and is engineered to be highly reliable.
