The document discusses Desktops as a Service (DaaS), which allows enterprises to host virtual desktops in a cloud provider's data center. DaaS eliminates the capital costs of owning desktop infrastructure while providing flexible access to Windows desktops from any device. DaaS is seen as a safer entry point to cloud computing than moving servers due to desktops being separated from sensitive on-premise data and systems. The document argues DaaS could eventually enable all branch office IT systems to be hosted in the cloud.

10. Enterprise VDI vs. DaaS: Shifting vs. Eliminating Capital CostsWith enterprise VDI, corporate-owned desktops PCs are substituted for virtual desktops housed on a corporate-owned desktop hosting infrastructureConversely, DaaS enables the infrastructure hosting the virtual desktops to be truly outsourced – owned and operated by a service providerThis makes DaaS is a better fit for organizations looking to truly lower desktop CAPEX and OPEX as opposed to simply shifting internal IT costs6©2009 Desktone, Inc. | All rights reserved.

12. The Promise of the CloudCloud computing is all the rage; surpassing the frenzy around virtualizationMany of today’s conversations are about how virtualization can take place in the cloudLots of touted benefits such as elasticity, anytime/anywhere accessNo CAPEX to get started; ongoing subscription economics8©2009 Desktone, Inc. | All rights reserved.

13. The Challenge of the CloudCloud computing for the enterprise in 2008/2009 = virtualized server workloadsShift introduces numerous challenges, most notably data securityMost server workloads are inextricably bound to their data tier; if you move the server, you need to move the dataMajority of enterprises are still uncomfortable having their data reside in a data center that’s not under their controlAlso, many back office servers are tightly integrated with other systems in the enterprise data center, which adds the to the complexity of moving them to the cloud9©2009 Desktone, Inc. | All rights reserved.

17. Start with Cloud-Hosted DesktopsDesktone believes virtual desktops – not servers – are a better place to start with enterprise cloud computingMost fixed corporate desktops environments are architected to have application and user data stored off the local disk in the enterprise data center (AD domain controllers, home drives for user generated data and client/server apps)13©2009 Desktone, Inc. | All rights reserved.

18. The Security of Cloud-Hosted DesktopsWhen you shift this kind of user environment to the cloud, the desktop instance has moved, but the data and back-end systems are still hosted in the enterprise data centerVirtual desktops are now running in a highly secure, virtual branch office of the enterprise – that is, the service provider data centerAdditionally, if you virtualize and centralize physical PCs from remote branch or home offices with limited or no physical security, you’ve actually increased the security of the environmentThis means the PC won’t:Walk off

25. Where’s this all headed?DaaS is just the starting point in a longer term vision of the “Branch Office in the Sky”This is the concept of virtualizing and centralizing all physical IT assets that currently live in distributed branch offices into a service provider cloudBranch IT assets include:Desktops

26. Servers (directory, file, print, web filter/proxy, mail)By moving branch office IT to a service provider cloud, organizations can finally get out of the extremely costly and distracting business of maintaining IT assets in their branches19©2009 Desktone, Inc. | All rights reserved.

27. ConclusionDaaS is an emerging, yet viable delivery model (alongside enterprise VDI) for hosted virtual desktopsDaaS = Cloud-Hosted DesktopsCloud-hosted desktops are the smart, low-risk way to enter the CloudHost virtual desktops with no CAPEX

28. Avoid moving sensitive systems and data to the cloud

29. Preserve the rich Windows client experience for end-users

30. Leverage existing IT operational and support models

31. Gain cloud-like benefits without full cloud migration

32. Choose between on-and off-premise hosting models (or both) 20©2009 Desktone, Inc. | All rights reserved.
