Amazon DynamoDB Accelerator now supports R7i instances

Amazon DynamoDB Accelerator (DAX) now supports R7i instances, powered by custom 4th Generation Intel Xeon Scalable processors. R7i instances provide instance sizes up to 24xlarge, feature an 8:1 ratio of memory to vCPU, and include the latest DDR5 memory. These instances are now available in the following AWS Regions: US East (N. Virginia, Ohio), US West (N. California, Oregon), Asia Pacific (Mumbai, Singapore, Sydney, Tokyo), Europe (Frankfurt, Ireland, London, Paris, Spain, Stockholm), and South America (Sao Paulo).

DAX is a fully managed, highly available caching service built for Amazon DynamoDB that improves performance from milliseconds to microseconds - up to 10 times faster - even at millions of requests per second. As a fully compatible service with existing DynamoDB API calls, DAX requires no application logic modification. The service manages all aspects of cache invalidation, data population, and cluster management, allowing developers to focus on building applications without worrying about performance at scale.
