Finally the pendulum swings back toward reality. Virtualization is interesting for many problem sets but it does add overhead and it has it’s costs. All of these technologies are cost -vs- reward and for too long we’ve been drinking the virtualization cool aide not realizing the real costs of those configurations. Last year I did a super low-latency high qps project on a cloud box and I was lucky to get 37k qps out of the box. I had the same exact box reloaded as bare metal and was able to get to 165k qps. Mind you this is latency in the neighborhood of 10ms and really extreme qps loads. That said the virtualization layer is not free, it’s useful as are many technologies and it’s an awesome tool for the right problem set. I’m happy to see Rackspace coming out with this, I asked them for something like this years ago and am excited to see they’ve figured out a way to do it.. Like many have said.. Let’s see the pricing. But before you compare make sure you are really comparing apples to apples.
