Network Overlays: An Introduction

Network overlays dramatically increase the number of virtual subnets that can be created on a physical network, which in turn supports multitenancy and virtualization features such as VM mobility, and can speed configuration of new or existing services. We’ll look at how network overlays work and examine pros and cons.

Thought Experiment--Forget ROI

Boys and girls, today's homework assignment is a thought experiment. I want you all to put yourselves in the shoes of the CXO team making a decision to move to private cloud. There is, of course, one catch: You may not factor in ROI. We're dropping ROI because it clouds the subject (bad pun intended.)
