I am trying to create an Amazon EC2 instance. I want to create a micro, 64-bit, Ubuntu 12.04 LTS instance.
In Amazon Web Services I have seen all instance have
AMI numbers. Now I found two ami(s) with numbers
ami-b8a8e9ea. both looks same to me - micro, ebs-based, 64-bit Ubuntu 12.04LTS images.
If so, what is the difference and why two number for the same machine image?
