I jut received this email this morning

Dear AWS Developers,

We are excited to release the public beta of Amazon Elastic Compute Cloud (Amazon EC2) running Microsoft Windows Server and Microsoft SQL Server. AWS is also announcing that Amazon EC2 is now Generally Available and includes a Service Level Agreement (SLA). In addition, we're giving you a sneak peek at some upcoming features that will make Amazon EC2 even easier to operate. Please see details below on these announcements.

You requested to be notified when Windows was available on EC2, and starting now you can employ Amazon EC2 running Windows Server or SQL Server with all of the performance, reliability, and scalability benefits of Amazon EC2. AWS customers have commonly requested Amazon EC2 running Windows Server since the service launched, and this announcement means that Amazon EC2 will provide an ideal environment for deploying ASP.NET web sites, high performance computing clusters, media transcoding solutions, and many other Windows-based applications. Like all services offered by AWS, Amazon EC2 running Windows Server or SQL Server offers a low-cost, pay-as-you-go model with no long-term commitments and no minimum fees. Pricing for Amazon EC2 running Windows Server begins at $0.125 per compute hour. Please go to aws.amazon.com/windows for more information.

Also, Amazon EC2 has entered General Availability (GA), after just over two years of operation in beta and the addition of many highly-requested features. We are also providing an SLA for Amazon EC2, with a service level commitment of 99.95% availability within a Region. If availability falls below this level, customers are eligible to receive service credits. 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. For further details on the SLA for EC2, see aws.amazon.com/ec2-sla.

Lastly, to help its customers better plan their future hardware and software investments, AWS is providing visibility into plans to release several new features in 2009 that will make managing cloud-based applications even easier. These features will help provide even more cost-efficient consumption of Amazon EC2 and greater visibility into the operational health of applications running in the AWS cloud. These features include:

• Load balancing - Enables AWS customers to balance incoming requests and distribute traffic across multiple Amazon EC2 instances.
• Auto-scaling - Automatically grows and shrinks usage of Amazon EC2 compute capacity based on application requirements.
• Cloud monitoring - Enables AWS customers to monitor operational metrics of Amazon EC2, providing visibility into usage of the AWS cloud.
• Management Console - Provides a simple, point-and-click web interface that lets customers manage and access their AWS cloud resources.

We are excited to share these exciting new announcements with you, and invite you to visit aws.amazon.com/ec2 for full details.

I can't tell how exciting this is. More to come on this!
