I recognize a lot of cynicism about Cloud Computing. People see it as a buzz word, which it is, and for this reason play down this technology trend. I think CIO's should not be happy when this happens in their office.
I am not going to explain or evangelize Cloud Computing in this blog posting. What I will do is refer to a downloadable powerpoint presentation by Pat Helland.
Pat Helland remade a paper of Berkeley's called Above the Clouds. Pat has made this document to an easy approachable yet comprehensive powerpoint presentation.
Every CIO dealing with applications in datacenters should be aware of what Berkeley try to tell us. I am really impressed by Berkeley's paper and Pat Helland's powerpoint sheets.
The 8 questions Berkeley answers in the paper are:
- What is Cloud Computing, and how is it different from previous paradigm shifts such as Software as a Service (SaaS)?
- Why is Cloud Computing poised to take off now, whereas previous attempts have foundered?
- What does it take to become a Cloud Computing provider, and why would a company consider becoming one?
- What new opportunities are either enabled by or potential drivers of Cloud Computing?
- How might we classify current Cloud Computing offerings across a spectrum, and how do the technical and business challenges differ depending on where in the spectrum a particular offering lies?
- What, if any, are the new economic models enabled by Cloud Computing, and how can a service operator decide whether to move to the cloud or stay in a private datacenter?
- What are the top 10 obstacles to the success of Cloud Computing—and the corresponding top 10 opportunities available for overcoming the obstacles?
- What changes should be made to the design of future applications software, infrastructure software, and hardware to match the needs and opportunities of Cloud Computing?
