Cloud and virtualization

In his Cloud Interoperability Magazine blog post title “Cloud Computing Surpasses Virtualization in Popularity”, Reuven Cohen writes

"I was recently looking at Google's trends & insights tool and noticed something very interesting has happened over the last month or so. For the first time the term "cloud computing" has surpassed "virtualization" in terms of search popularity. What is all the more interesting is it took cloud computing a little over a year and half compared to nearly 5 years for virtualization to see the same level of search volumes. Astounding growth to say the least.


I think this is no surprise. Virtualization addresses only one part of cloud computing paradigm IMO – how to realize it technically. A cloud is much more than that, covering the larger spectrum of I.T services and not just the infrastructure. As I wrote here earlier, cloud computing is multi-dimensional and should cover the presently fragmented

1. Cloud of infrastructure services(IaaS, PaaS)
2. Cloud of internal enterprise shared services (the ‘internal cloud’)
3. Cloud of externally provisioned software services (SaaS)
