### AI overview

An AWS resilience guide examines a correlated EC2 hardware failure that took down three colocated Cassandra nodes. It covers placement groups, alarms, automated recovery, and observability patterns for distributed data systems.

### Source excerpt

Learn how to prevent correlated hardware failures in distributed systems on Amazon EC2. This post walks through real incident response patterns, including Partition Placement Groups, composite alarms, automated recovery with Auto Scaling, and observability best practices.
