Can ASP.NET MVC3 Applications Host in cloud without specific code changes?

I had created an asp.net web app using:

-ASP.NET MVC 3 Webforms

-Linq to sql

-MSsql server database.

-WCF

What would need to be done to host it on a cloud service? Should i convert it in to Azure application or not. can i directly upload my ASP.Net MVC Web application in a Cloud without specific code changes that would be required before hosting.
