Amazon ElastiCache for Redis announces improved maintenance update procedures for auto failover enabled clusters. You can now benefit from improved availability during patching, updates and other maintenance related activities that involve planned node replacements. For Redis Cluster configurations that are set up to use Redis Cluster clients, the planned node replacements will now complete without any interruption. For non-Redis Cluster configurations, you may notice a brief interruption, of up to a few seconds, associated with DNS update.

Amazon ElastiCache for Redis conducts and manages maintenance-related node replacements to enhance security, reliability, and operational performance of your clusters. Node replacements typically occur during your cluster’s maintenance window. With this release, all new and existing Amazon ElastiCache for Redis clusters that are configured with auto-failover enabled will benefit from improved availability during such planned maintenance. 

The new improvements are available in all commercial Amazon Web Services regions. To learn more about Amazon ElastiCache planned maintenance, see here .To get started with Amazon ElastiCache, log into the Amazon Web Services Management Console
