Two New EC2 Instance Types Now Available: Large and Extra Large

So now you can scale up and out on EC2. Very, very nice. The original size is now called a Small Instance. Here are the specs and prices:

Small Instance (default)*

1.7 GB memory
1 EC2 Compute Unit (1 virtual core with 1 EC2 Compute Unit)
160 GB instance storage (150 GB plus 10 GB root partition)
32-bit platform
I/O Performance: Moderate
Price: $0.10 per instance hour

Large Instance (~4 small instances)

7.5 GB memory
4 EC2 Compute Units (2 virtual cores with 2 EC2 Compute Units each)
850 GB instance storage (2 x 420 GB plus 10 GB root partition)
64-bit platform
I/O Performance: High
Price: $0.40 per instance hour

Extra Large Instance (~8 small instances)

15 GB memory
8 EC2 Compute Units (4 virtual cores with 2 EC2 Compute Units each)
1,690 GB instance storage (4 x 420 GB plus 10 GB root partition)
64-bit platform
I/O Performance: High
Price: $0.80 per instance hour

If I were them, I probably would have called them Tall, Grande and Venti instances.
