Of course SharePoint does not work in Windows Azure (yet), but there are ways to integrate with and leverage SharePoint capabilities with Windows Azure. Here are some resources that illustrate how to do this. (See Steve Fox’s blog for more ideas on the subject.)
- PDC 2010 Session: Integrating SharePoint with Windows Azure
- MSDN Magazine article: Connecting SharePoint to Windows Azure with Silverlight Web Parts
- MSDN Webcast – Level 300: SharePoint 2010 and Windows Azure (Level 300)
- PowerPoint Deck – SharePoint and Windows Azure: How They Play Together
- Several of Steve Fox Blog posts:
- SharePoint and Azure: How They Play Together? (this includes code snippets, etc.)
Of course if you need SharePoint running in the cloud today you should investigate Office 365 which provides many of the features of on-premise SharePoint via SharePoint Online.
