Cross-Region Replication Is Not Resilience
The article discusses the misconception that cross-region replication equates to resilience in disaster recovery. While replication ensures data is current and available in a separate location, it does not guarantee effective recovery from disasters. The author emphasizes the importance of distinguishing between data replication and actual recovery capabilities.
- ▪Cross-region replication maintains a copy of data in a separate location but does not ensure service recoverability.
- ▪Replication addresses Recovery Point Objective (RPO) but does not contribute to Recovery Time Objective (RTO).
- ▪Replication can propagate destructive changes, such as ransomware, without detection, making it a poor substitute for true recovery solutions.

It is said with confidence, because by every metric the team watches, it is true. The replica is current. Lag is measured in seconds. The dashboard is green. And that confidence is precisely the problem.
