Recently, I read the techcruch post on the Mediatemple grid servers. I decided to get an account. We even decided to use them at work for the corporate site. It works ok for static content, but I’m now suspicious of their scalability claims. At first, it sounded like they were doing something interesting with virtual servers. In fact, the techcrunch post mentions that the service is comparable to the EC2 service by Amazon. The reality, of course, is much different.
Here is a great blog post which covers what Mediatemple is truly using for their ‘grid technology’.
