Coming Soon – New Memory-Optimized EC2 Instances

by Jeff Barr | on | in Amazon EC2 | | Comments

At last week’s AWS Summit in San Francisco, Senior VP Andy Jassy announced the forthcoming R3 instance type (watch Andy’s presentation), and presented a map to illustrate the choices:

I’d like to provide you with some additional technical and pricing information so that you can start thinking about how you will put this powerful new instance to work.

Soon to be available in five instance sizes, this instance type is recommended for applications that require high memory performance at the best price point per GiB of RAM. The R3 instances include the following features:

  • Intel Xeon E5-2670 v2 “Ivy Bridge” Processors
  • Hardware Virtualization (HVM) only
  • SSD-backed instance storage, including TRIM support
  • Enhanced Networking with lower latency, low jitter, and high packet-per-second performance

The R3 instances will be available in five sizes, as follows (prices are in US East (Northern Virginia); see the EC2 pricing page for full information):

Instance Name vCPU Count RAM
Instance Storage (SSD) Price/Hour
r3.large 2 15 GiB 1 x 32 GB $0.175
r3.xlarge 4 30.5 GiB 1 x 80 GB $0.350
r3.2xlarge 8 61 GiB 1 x 160 GB $0.700
r3.4xlarge 16 122 GiB 1 x 320 GB $1.400
r3.8xlarge 32 244 GiB 2 x 320 GB $2.800

You will be able to launch the r3.xlarge, r3.2xlarge, and r3.4xlarge instances in EBS-Optimized form, with additional, dedicated I/O capacity for EBS volumes. The r3.8xlarge instance features 10 Gigabit networking.

Stay tuned to this blog, or follow me on Twitter and you’ll be among the first to know when you can start launching some R3 instances.
