A pragmatic approach to RPO zero
Nobody wants to lose data—and setting a Recovery Point Objective (RPO) to zero makes this intent clear. Customers with government mission-critical systems often need to meet this requirement, since any amount of data loss will cause harm. RPO covers both resilience and disaster recovery—everything from the loss of an individual physical disk to an entire data center. Existing systems support RPO zero through a combination of architecture patterns (including resilient messaging) and on-premises legacy databases. Frequently interpreted as a database or storage requirement, providing for RPO zero requires thinking about the entire system. To do so, you can use AWS services and architecture patterns, which provide resilience to failure with clustering, auto scaling, and failover across multiple data centers within one region.
