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.

18. So, here are the various optionsApplication runs on-premisesBuy my own hardware, and manage my own data centerApplication runs on-premisesBring my own machines, connectivity, software, etc.

19. Complete control and responsibility

20. Upfront capital costs for the infrastructureApplication runs at a hosterPay someone to host my application using hardware that I specifyApplication runs at a hosterRent machines, connectivity, software

21. Less control, but fewer responsibilities

22. Lower capital costs, but pay for fixed capacity, even if idleApplication runs using cloud platformPay someone for a pool of computing resources that can be applied to a set of applicationsApplication runs using Public cloud platformShared, multi-tenant environmentOffers pool of computing resources, abstracted from infrastructure
