After a full day doing exaustive real-world tests, I was surprised to find that the “High-CPU Medium” EC2 instance type is the best value for my work. I have a lot of interesting data to post, but here’s a first simple chart for now
Shorter bars are better. The blue bars are time to complete the task, uncompressing a 55 MB mysql database dump with bunzip2. I’m experimenting with this chart: I stacked the cost on top of the times to give a sort of “cumulative value” result. Full details coming in a followup post.
