Windows Azure Operating System Versioning

If you are working with Azure already then you probably were wondering how versioning of the operating system will work and how you can make sure that upgrades and patches do NOT have any negative impact on your cloud application. Now we got some answers on that issue:


Operating System Versioning in Windows Azure

Customers can now choose when their applications receive new operating system updates and patches by selecting which version of the operating system their applications will run on in Windows Azure.  Right now there is only one available operating system version (released on December 17th, 2009), but new builds with the latest updates and patches will be released regularly.  This new feature allows developers to test their applications when new patches come out before upgrading their production deployments.

To select an operating system version for your application, add the new osVersion attribute to your service configuration file.  The full list of available operating system versions is maintained in the Configuring Operating System Versions topic in the Windows Azure MSDN documentation.
