Question

A parks-and-recreation registration app still uses a single-AZ Amazon RDS instance. An AZ impairment would take citizen payments offline with no tested failover. Which reliability remediation should the team implement first?

Accepted Answer

Convert to Multi-AZ RDS, document and rehearse failover, and verify the app reconnects within the registration RTO — One AZ is one blown fuse away from angry parents who cannot sign kids up for summer camp. Flip the database to Multi-AZ and actually practice the failover—paper plans do not cash checks.

Answer

Add a second reader in the same AZ only and treat it as full DR

Answer

Turn off automated backups to reduce failover complexity

Answer

Snapshot the database annually to Amazon S3 Glacier Flexible Retrieval and stop here
