Of Cloud Computing and Virtualization
There still continues to be an immense amount of confusion around what exactly constitutes cloud computing. As an example, over the last few days, there has been a spirited debate whether the Sidekick service Microsoft/Danger offered was a cloud-based service or not (I am not going to dig into that here, but I do happen to agree with Chris Hoff’s viewpoint).
A common question I get is if virtualization is an inherent and mandatory component of any cloud solution. I bounced this question up to our CTO’s office to get their take on things. Their perspective:
Cloud computing delivers IT resources on-demand and elastically, and many organizations would like to leverage these capabilities today. Compute virtualization established itself as a way to improve resource utilization, but has other characteristics that make it more broadly relevant to cloud.
To expound on this a bit further, Glenn Dasmalchi, technical chief of staff in the office of the CTO at Cisco, provides a summary of how cloud computing and virtualization are related, and what advantages are afforded to customers. He also touches on the network play with the cloud-virtualization linkage.
