    Hi Victor,

    In a Multi-AZ deployment, RDS automatically provisions and maintains a synchronous standby replica in a different AZ. The primary DB instance is synchronously replicated across AZs to a standby replica to provide data redundancy, eliminate I/O freezes, and minimize latency spikes during system backups.

    A “standby replica” is not the same with “Read Replica”. For more information, please read the following AWS documentation:

    https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.MultiAZ.html
