I believe that Cloud Computing represents a classic example of an implementation of SOA Services, with full power of separation of ownership and all related problems. The presentation I will be making at the OASIS Cloud Identity conference in London (in July) is about one of such 'problems'. Actually, it is a problem only in the opinion of traditional inside-enterprise custom of dealing with user identities.
Real problems have raised from the business independency of Cloud providers; these problems have been outlined many times by corporate executives who tried to manage Cloud in the same way they dealt with their internal IT; this simply did not work.
Based on this view, I have wrote a few articles on this topic:
1) a check-up list of what should be in the Service Contract with a Cloud Provider [http://www.clingstone.co.uk/a-checklist-for-contracting-cloud-business/]
2) a different, client-centric, classification of Clouds - public vs. private [https://www.linkedin.com/pulse/20140826154021-6259328-a-shift-in-understanding-of-private-and-public-cloud?trk=mp-reader-card]
3) a different, client-centric, interpretation of Hybrid Clouds [https://www.linkedin.com/pulse/20140927140218-6259328-re-thinking-hybrid-cloud?trk=mp-reader-card]
There are two viewpoints on Cloud Computing: consumer's and provider's one. They directly impact the understanding of the Cloud economy and, thus, the role of all Cloud attributes. There are many of them. For example, Cloud's elasticity is: 1) a detail of the implementation of Cloud service; 2) a major mechanism of Cloud economy to the provider; 3) a reasonable feature - pay for what you use - for the consumers, but nothing more than this (consumers do not care how a Cloud service operates). At the same time, a low cost of Cloud becomes a Providers' myth for Consumers when the latter count a full cost of Cloud service 'ownership'/usage.
I think we can ask the Martin's question with regard to a general renting/leasing business and alike.

Can anyone recommend a concise summary of the relationship between service-oriented architecture and Cloud computing?
Also, is virtualization just an enabler (of the Cloud's elasticityattribute, for example) or something more?
Thanks,
Martin
