How to port WCF/SQL app to (SQL) Azure cloud?

I've got a local app, consisting of a windows service providing the middle/business tier for a SQL Server database (c#, .net 4, SQ开发者_JAVA百科L Server 2008 R2)

Now I'd like to port this app to Windows Azure Cloud (both service and SQL database). Is somewhere a document stating the differences between a local WCF service and a windows Azure Service, same for local SQL Server and SQL Azure?

Any pointers how to start porting from WCF to Azure?

For SQL Server vs SQL Azure, look at this MSDN page. You'll see a whitepaper link documenting the fundamental differences between SQL Server and SQL Azure. Here are additional links:

• General Guidelines and Limitations
• T-SQL Support

For WCF in Azure, you'll need to learn about the ways to host WCF in either a WCF Service Web Role or a Worker Role. You'll also have to understand the new binding types available if accessing WCF over the Service Bus. Here are a few links to get you started:

• Azure WCF samples and discussions
• Patch to let WCF work properly in Azure, due to load balancer issues
