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.
