MySQL on EC2 - More Info and some Testing
Here is a quick post by our folks at RightScale who did some quick benchmarks on MySQL performance of different EC2 instance sizes. Interesting data for sure. I can think of a few other good tests to do here and I'm hoping to test them myself very soon as well. I hope to post my results here.
