Amazon DynamoDB Accelerator (DAX) now supports encryption at rest for new DAX clusters to help you accelerate reads from Amazon DynamoDB tables in security-sensitive applications that are subject to strict compliance and regulatory requirements.
DAX provides you a fully-managed, highly available, in-memory cache that is capable of accelerating reads from DynamoDB tables by up to 10x, even at millions of requests per second. You can use DAX without making changes to your existing application logic and using your existing DynamoDB APIs calls. DAX manages cache invalidation and data population on your behalf. With the new encryption at rest support, you can also encrypt the storage for your DAX clusters to help you protect data on your DAX nodes, such as configuration and log files. This data is encrypted using AWS Key Management Service (AWS KMS).
DAX is available in the US East (N. Virginia), US East (Ohio), US West (Oregon), US West (N. California), South America (São Paulo), EU (Ireland), Asia Pacific (Singapore), Asia Pacific (Tokyo), Asia Pacific (Sydney), and Asia Pacific (Mumbai) Regions.
