A Multi-Availability Zone database (DB) deployment is beneficial when a customer wants to increase the availability of their database. What are other benefits of a Multi-AZ deployment?

Running a Multi-AZ DB deployment with high availability can enhance availability during planned system maintenance by providing automatic DB failover. It can also help protect DB performance by backing up from your standby instance while your primary DB is running. If using a Multi-AZ DB deployment with one standby, your standby DB instance is only a passive failover target for high availability.
