First off, the question asked about the benefits of adding “Multi-AZ deployments” in Amazon RDS. It is true that by default, RDS will only launch a single database instance in a single AZ, unlike Aurora with multiple replicas across multi-AZs.
However, it doesn’t mean that you can not make your RDS database highly available. You can certainly make it fault-tolerant to one or more AZ failure, by setting up a Multi-AZ Deployments configuration.
