Aurora Replica to the primary instance is much faster than creating a new primary I used the same script and data between Multi-AZ and Single-AZ instances. When a problem affects the primary instance, one of these If something were to cause the Availability Zone where your server instance resides to shutdown, your database would cease to function, as the physical server instance is offline. Configure the application reader endpoint for reports. More than one Aurora Replica can share the same priority, resulting in promotion tiers. Many Aurora features apply to the failover mechanism. The storage layer is an SSD-backed virtualized representation of all the actual data within your database.
