This is in response to bwoolf's posting "Re: Silver Lining: You can start now with Cloud Computing!!" where he raised a very interesting discussion point and questions of clarification.
Firsty, thanks for your comments and the reference to your blog on grid. It looks like IBM had a true premonition on the "Future of Computing" :-).
You've raised a very interesting discussion point and I'll attempt to answer your questions. The key premise I often refer to is that SOA is an enabler of the Cloud. As are other enablers such as virtualization and grid computing technologies amongst others. These enablers facilitate the Cloud's ability to deliver business services as provisioned services in a low cost, automated, virtual and transparent way. Subscribers can now benefit from the business value of these services (be them defined by SOA or other) with a significantly reduced overhead of investment compared to what they would incur if they were to own the implementation and delivery of these services and their underlying resources.
So is the "Silver Lining: You can start now with Cloud Computing!!" blog entry about SOA or Cloud Computing? I would like to say the latter but based on the example you are right to conclude that SOA is all over it as you may find in other blogs about Cloud Computing where there may be references to virtualization, grid computing etc.
It looks like we are somewhat in agreement on the point that SOA and Cloud go hand-in-hand :-) In fact that's one of the "Silver Linings of Cloud Computing" I've expressed in that we are already familiar with the technology and architectural concepts (such as SOA) that constitute the Cloud.
Once again thanks for your valuable comments and bringing this discussion point to the table!!!
