Wow, that was fast. Amazon Web Services, which said three weeks ago it would begin offering Windows on its Elastic Compute Cloud in closed beta, has opened the beta service up for all. Even bigger news is the beta tag has been removed from the rest of the EC2 service, and users now have a 99.95 percent up-time service level agreement. Yesterday, Rackspace ran hard to keep up with Amazon’s cloud offerings — acquiring two startups — but, with a full production computing cloud out of beta, it looks like Amazon is still in the lead.
Rackspace has Mosso which offers Linux and Windows cloud hosting for a while now.
It is good to hear that amazone has opened windows. This is good news for sites running on windows server, asp.net & other .Net component.
