AWS continuously scans disks that carry Aurora data and automatically uses its self-healing technology to repair data, as needed. Data is replicated six times among three availability zones having 2 in each AZ. Any Aurora read replicas you create (up to a max of 15 at this time) are also available as failover targets. The keyword to focus on here is virtualized, which is Amazon’s fancy way of saying that the storage layer which represents the actual data in your system is not attached to any one physical location or machine, but instead is virtualized and propagated to numerous locations (six in total across three Availability Zones in most cases). By default, the Multi-AZ feature is not enabled for the RDS instance. One RDS instance can contain multiple databases created by the users.

To fully understand what a Multi-AZ Deployment means for your infrastructure, it’s critical to recognize how Amazon Web Services is configured across the globe and thus how it provides the redundancy services no matter your location. When you enable a multi-AZ deployment, we create an Aurora read replica that is available as a failover target. In Aurora, when you specify a Multi-AZ configuration during creation, an Aurora replica is created in a second availability zone. This replica will be used as a failover target in case that the primary becomes unavailable. ... then the RPO for Single-AZ, Multi-AZ, and even Aurora is typically around 5 minutes.
