## AI overview

This tutorial explains how Amazon RDS Multi-AZ deployments handle database failures and failover. It examines RDS architecture, including EC2 compute, EBS storage, VPC connectivity, the control plane, storage-level replication, and Availability Zone isolation.

## Source excerpt

Database failures are inevitable. Even with the most reliable hardware and software, something will eventually break. AWS RDS Multi-AZ deployments promise to handle these failures gracefully, automatically failing over to a standby database when prob...
