ElastiCache T2 Support
As you may already know, Amazon Elastic Compute Cloud (Amazon EC2)‘s new T2 instance type provides a solid level of baseline performance and the ability to burst above the baseline as needed. As I wrote in my blog post, these instances are ideal for development, testing, and medium-traffic web sites.
Today we are bringing the benefits of the T2 instance type to Amazon ElastiCache. The cache.t2.micro (555 megabytes of RAM), cache.t2.small (1.55 gigabytes of RAM), and cache.t2.medium (3.22 gigabytes of RAM) cache nodes feature the latest Intel Xeon processors running at up to 3.3 GHz. You can launch new cache nodes using the Memcached or Redis engines.
T2 instances are supported only within an Amazon Virtual Private Cloud (Amazon VPC). The Redis Backup and Restore feature and the Redis AOF are not currently usable with the T2 instances. You can launch them in the usual ways (command line, API, CloudFormation, or Console):
Pricing and Availability
Pricing for T2 cache nodes starts at $0.008 per hour for Three Year Heavy Utilization Reserved Cache Nodes and $0.017 per hour for On-Demand Cache Nodes. (see the ElastiCache Pricing page for more information). As part of the AWS Free Tier, eligible AWS users have access to a cache.t2.micro instance for 750 hours per month at no charge.
The new cache nodes are available today in all AWS Regions except AWS GovCloud (US) and you can start using them today!
