Amazon EC2 users now have access to a pair of new “High-CPU” instance types. The new instance types have proportionally more CPU power than memory, and are suitable for CPU-intensive applications. Here’s what’s now available:

The High-CPU Medium Instance is billed at $0.20 (20 cents) per hour. It features 1.7 GB of memory, 5 EC2 Compute Units (2 virtual cores with 2.5 EC2 Compute Units Each), and 350 GB of instance storage, all on a 32-bit platform.

The High-CPU Extra Large Instance is billed at $0.80 (80 cents) per hour. It features 7 GB of memory, 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each), and 1,690 GB of instance storage, all on a 64-bit platform.

The AWS Simple Monthly Calculator now supports these new instance types.

We’ve been working with a number of tool vendors to line up early support for this important new feature. I plan to update the blog post several times in the coming days as this support becomes available.
