There's more competition in the "compute power on the web" competition (see related posts). Via TechCrunch we learn of MediaTemple's Grid-Server:

(mt) Media Temple's Grid-Server is a completely new hosting platform that replaces yesterday’s obsolete shared server technology. We've eliminated roadblocks and single points of failure by using hundreds of servers working in tandem for your site, applications, and email. The Grid's on-demand scalability means you'll always be ready for intense bursts of traffic and the growing audience resulting from your online success. All of this power, controlled through our brand new AccountCenter, is available today for a price point unmatched by any competing service.

It looks pretty feature full, though the website skews marketing speak so it's difficult to tell if I can put _my_ app (whatever that may be) up there or do I need to do something special.
