As I have been playing around with EC2 one of things that seemed to be missing were bigger instances with more CPU and memory. Amazon describes their base instance as “One EC2 Compute Unit provides the equivalent CPU capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor.” and has 1.7GB of RAM. That works really well in most cases, but I was wanting to see something a little bigger for a MySQL database machine . Amazon rolled out some larger instance types just recently that seem to fit the need.
