Maximise database availability
summary
Amazon Aurora and DynamoDB provide concrete availability patterns: Aurora uses a six-way quorum across three AZs with writes acknowledged after four replicas, auto-failover to up to 15 replicas, continuous backups to S3 and point-in-time recovery to any second for up to 35 days, and global DB replication with RPO 1s RTO <1min and sub‑second cross‑region latency; DynamoDB delivers single‑region five nines availability, DynamoDB Global Tables for multi‑region active‑active writes with last‑writer‑wins, single‑digit ms latency and on-demand backups hundreds of TB.
