Beta level support for Microsoft Windows is now available on Amazon EC2, in the form of 32 and 64 bit AMIs, with pricing starting at $0.125 per hour. Microsoft SQL Server is also available in 64 bit form.
With over two years of operation and many highly-requested features added, Amazon EC2 is today exiting its beta into general availability and offering customers a Service Legal Agreement (SLA). The Amazon EC2 SLA guarantees 99.95% availability of the service within a Region over a trailing 365 day period, or customers are eligible to receive service credits back. The new Amazon EC2 SLA is designed to give customers additional confidence that even the most demanding applications will run dependably in the AWS cloud.
