Amazon ElastiCache for Memcached now supports encryption of data in transit using Transport Layer Security (TLS) version 1.2. When using encryption in transit, all network traffic between your clients and Memcached cluster are encrypted.

You can easily set up in-transit encryption by enabling it when creating your Memcached cluster via the AWS Management Console, AWS CLI, or the AWS SDK. ElastiCache automatically manages the issuance, renewal, and expiration of your TLS certificates. TLS support was also added for Memcached PHP and Java clients, both available for download from the AWS Management Console for ElastiCache.

Encryption of data in transit for ElastiCache for Memcached is supported when using version 1.6.12 and above, and is available in all public AWS Regions and AWS GovCloud (US) at no additional cost.

To get started, create a new Memcached cluster using the AWS Management Console for ElastiCache. For more information, see the ElastiCache for Memcached 1.6.12 release notes and the encryption in transit  section in the ElastiCache documentation.
