Amazon MemoryDB now supports an AWS Fault Injection Service action to pause replication for multi-Region clusters. FIS is a fully managed service for running controlled fault injection experiments to improve an application’s performance, observability, and resilience. Amazon MemoryDB Multi-Region is a fully managed, active-active, multi-Region database that lets you build multi-Region applications with up to 99.999% availability and microsecond read and single-digit millisecond write latencies. Customers can use the new FIS action to observe how their application responds to a disruption in regional replication, and tune their monitoring and recovery process to improve resiliency and application availability.
MemoryDB Multi-Region enables you to build multi-Region applications that need high availability, increased application resiliency, and improved business continuity. This new FIS action reproduces the real-world behavior when replication in a multi-Region cluster is interrupted and resumed. This lets you test and build confidence that your application responds as intended when resources in a Region are not accessible. You can create an experiment template in FIS to integrate the experiment with continuous integration and release testing and to combine with other FIS actions. For example, MemoryDB Pause Replication is combined with other actions in the Cross-Region: Connectivity scenario to isolate a Region.
MemoryDB Multi-Region Pause Replication is now available in all AWS Regions where MemoryDB Multi-Region is available. To learn more, visit the MemoryDB FIS actions documentation.
