ElastiCache Update – New M3 and R3 Instance Types

You can use Amazon ElastiCache to add a scalable caching layer to your application. As you may already know, you can use ElastiCache to create a Memcached or Redis Cache Cluster comprised of one or more Cache Nodes.

Today we are making ElastiCache even more flexible by adding support for two new types of Cache Nodes. The M3 Cache Nodes provide a balance of compute, network, and memory resources and are a perfect choice for general purpose use. The Memory-optimized R3 Cache Nodes provide the best price per GB of RAM and high memory performance. Here’s the full set of new instances:

  • cache.m3.medium – 2.78 GB memory
  • cache.m3.large – 6.05 GB memory
  • cache.m3.xlarge – 13.3 GB memory
  • cache.m3.2xlarge – 27.9 GB memory
  • cache.r3.large – 13.5GB memory
  • cache.r3.xlarge – 28.4GB memory
  • cache.r3.2xlarge – 58.2 GB memory
  • cache.r3.4xlarge – 118 GB memory
  • cache.r3.8xlarge – 237 GB memory

You can launch these new types of Cache Nodes today in the following AWS Regions:

  • US East (Northern Virginia)
  • EU (Ireland)
  • Asia Pacific (Singapore)
  • Asia Pacific (Tokyo)
  • Asia Pacific (Sydney)
  • US West (Oregon)
  • US West (Northern California)
  • South America (São Paulo) – M3 only.
  • China (Beijing) – M3 only.

You can launch Cache Clusters from the AWS Command Line Interface, the ElastiCache API, or the AWS Management Console. Here’s the first page of the console’s launch wizard:
