10.

The Promise of the Cloud Cloud computing is all the rage; surpassing the frenzy around virtualization Many of today’s conversations are about how virtualization can take place in the cloud Lots of touted benefits such as elasticity, anytime/anywhere access No CAPEX to get started; ongoing subscription economics 8 ©2009 Desktone, Inc. | All rights reserved.

13. The Challenge of the Cloud Cloud computing for the enterprise in 2008/2009 = virtualized server workloads Shift introduces numerous challenges, most notably data security Most server workloads are inextricably bound to their data tier; if you move the server, you need to move the data Majority of enterprises are still uncomfortable having their data reside in a data center that’s not under their control Also, 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 cloud 9 ©2009 Desktone, Inc. | All rights reserved.
