This document discusses migrating existing applications to Windows Azure. It provides an overview of cloud computing models including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). It also describes the key services available on the Windows Azure platform, including compute, storage, SQL Azure database, and .NET services. Finally, it discusses typical application scenarios for Windows Azure and provides resources for learning more.
