Customers can begin using the new functionality by simply enabling this functionality via AWS console, and a small configuration change in their Redis clients. The ElastiCache for Redis service automatically manages life cycle of the certificates required for encryption, including the issuance, renewal and expiration of certificates. Additionally, as part of this launch, customers will gain the ability to start using the Redis AUTH command that provides an added level of authentication.
