Wow

Amazon EC2 gets two new types of instances, large and extra large EC2 instances. Basically a large instance that has 4 times the capacity (CPU, RAM, HDD) of the old, now default small instance type while the extra large instance type has 8 times the capacity.

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

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

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

The idea is that you specify the instance type in the RunInstances API call. All old tools that do not specify this parameter start a default instance type.

Very nice to see this so fast after the recent S3 SLAs.

If they would now allow to run EC2 instances in Europe there are no excuses left not to run nearly all applications on EC2.
