Ensure ElastiCache Redis uses Multi-AZ with automatic failover

Multi-AZ deployment with automatic failover provides high availability by automatically promoting a replica if the primary node fails.

Security Impact

Without Multi-AZ, node failures result in cache downtime and potential application outages until manual intervention.

How to Remediate

Enable Multi-AZ with automatic failover for production Redis clusters. Deploy replica nodes in different availability zones.
