Yesterday Amazon launched a new EC2 Version including support for Windows and SQL Server.
Unfortunately it only runs Windows 2003 Server and SQL Server 2005. Now that we are all happy about Windows 2008, the new IIS7, the new URL Rewriting features and so on.
This really is a pity. I’d really like to use Amazon EC2, but I don’t want to take two steps back in development. Once you worked with IIS7 you don’t want to switch back to the old and clumsy IIS6. Especially URL Rewriting is so nice with IIS7.
There is a thread running on the EC2 Forum, but until now noone from Amazon replied. If you’re registered there you might want to drop a reply, too: http://developer.amazonwebservices.com/connect/thread.jspa?threadID=25660.
UPDATE:
Thanks for all of your feedback. Our intention is to support the widest variety of options for our customers that we can. We are already working to support Windows 2008 in EC2, and anticipate being able to offer it publicly in the early part of next year.
