Running a Small 64bit Amazon EC2

64-bitamazon ec2cloud

I'm playing with Amazon EC2, and I've got a 64bit AMI, but when I launch it, the 'Instance Type' only has 'Large', 'Extra Large' and 'High-CPU Extra Large', no 'Small' which the documentation lists as the default and the cheapest.

Is it cause I'm using 64bit? Can you run a small EC2 instance on 64bit AMI?

Today Amazon released the news that they support 64-bit for m1.small instances, as well as the new m1.medium instances.

No, the small instances are 32-bit only while the large/extra large instances are 64-bit, so you need to use either the large, extra-large or high-CPU extra-large instances for a 64-bit system.

See the EC2 instance type list for more details on the different types.
