When we talk about our next generation data centers, and how we are going to run them, recently, many of our discussions have turned to policy. How do we want our applications to be deployed? What type of service levels do we want them to have? Which virtual machines or instances should be present on …

NFV is Network Function Virtualization, and is actually a separate concept from SDN. While SDN focuses on mostly layer 2 and layer 3 functionality, NFV is focused on layers 4 through …

Virtualization set the stage for our future data centers, by software defining hardware, and other technologies are catching up. One area I think is particularly interesting is the open …

Cloud.com set out to develop on open source software to, well, power clouds, whether the be public or private. In 2010, when they emerged from stealth mode, they began …
Many of us remember when virtualization was in its infancy, when we didn’t have features like high availability to protect against hardware failures, and live migration to move a virtual server off of the host it resided on for maintenance. Back then, the benefits were all about reduced power and cooling requirements, and using less …
