In The Beginning

“One of the key challenges for corporate IT departments, in fact, lies in making the right decisions about what to hold onto and what to let go”Nicholas Carr, The Big Switch

“This (cloud computing) is a new way, but it’s not going to replace the existing –on-premise software is not going to go away.”Paul Slakey, Google, May 2008

“…it would be shortsighted to focus only on shifting IT services away from on-premises implementations. Instead, the ability to choose how an IT service is delivered from on-premises data centers to private clouds, off-premises utilities or even the public cloud is most critical.”Gartner Cloud Computing Report Series, June 2008

Scope started small

User Experience matters

New devices are emerging

One size does not fit all

Where should processing be done?

Federations of loosely coupled co-operating systems and loosely coupled compositions

Infrastructure and solutions should extend from server to cloud
