Amazon ElastiCache for Redis adds support for Redis 6 with managed Role-Based Access Control (RBAC)

Amazon ElastiCache for Redis now supports Redis 6. This release brings several new and important features to Amazon ElastiCache for Redis.

• Managed Role-Based Access Control – Amazon ElastiCache for Redis 6 now provides you with the ability to create and manage users and user groups that can be used to set up Role-Based Access Control (RBAC) for Redis commands. You can now simplify your architecture while maintaining security boundaries by having several applications use the same Redis cluster without being able to access each other’s data. You can also take advantage of granular access control and authorization to create administration and read-only user groups. Amazon ElastiCache enhances the new Access Control Lists (ACL) introduced in open source Redis 6 to provide a managed RBAC experience, making it easy to set up access control across several Amazon ElastiCache for Redis clusters.

• Client-Side Caching - Amazon ElastiCache for Redis 6 comes with server-side enhancements to deliver efficient client-side caching to further improve your application performance. Redis clusters now support client-side caching by tracking client requests and sending invalidation messages for data stored on the client. In addition, you can also take advantage of a broadcast mode that allows clients to subscribe to a set of notifications from Redis clusters.

• Significant Operational Improvements - This release also includes several enhancements that improve application availability and reliability. Specifically, Amazon ElastiCache has improved replication under low memory conditions, especially for workloads with medium/large sized keys, by reducing latency and the time it takes to perform snapshots. Open source Redis enhancements include improvements to expiry algorithm for faster eviction of expired keys and various bug fixes.

Note that open source Redis 6 also announced support for encryption-in-transit, a capability that is already available in Amazon ElastiCache for Redis 4.0.10 onwards. This release of Amazon ElastiCache for Redis 6 does not impact Amazon ElastiCache for Redis’ existing support for encryption-in-transit.
