Windows Azure Toolkit for Facebook

Welcome to the Windows Azure Toolkit for Facebook. This toolkit was built by Thuzi in collaboration with Microsoft to give the community a good starter kit for getting Facebook apps up and running in Windows Azure. Facebook apps hosted in Azure provide a flexible and scalable cloud computing platform for the smallest and largest of Facebook applications. Whether you have millions of users or just a few thousand, the Facebook Azure Toolit helps you to build your app correctly so that if your app is virally successful, you won't have to architect it again. You will just need to increase the number of instances you are using, then you are done scaling. :)
