In part one of this series, I tried to apply context to the virtualization market—its history, how it’s changed the way we deploy infrastructure, and how it’s developed into the de facto standard for infrastructure deployment. Over the last 20 years, virtualization has had a very positive impact in enabling us to deliver…
During this series, we’ve looked at virtualization’s past, the challenges it has created, and how its evolution will allow it to continue to play a part in infrastructure delivery in the future. In this final part, I’d like to draw these strands together and share how I believe the concept of virtualization will continue…
In the first two parts of this series, we looked at both the history of virtualization and the new set of problems it’s introduced into our infrastructures. In part three, we’ll investigate its evolution and how it will continue to be part of our technology deployments. A Software-Defined Future The future for…
In over 20 years I’ve spent in the IT industry, I’ve seen many changes, but nothing has had a bigger impact as virtualization. I remember sitting in a classroom back in the early 2000s with a server vendor introducing VMware. They shared how they enabled us to segment underused resources on Intel servers into something…
The Dream of the Data Center For me, it started with OpenStack. I was at a conference a number of years ago listening to Shannon McFarland talking about using OpenStack to bring programmatic Network Functions Virtualization (NFV) into the data center. My own applications are much more small-scale, but the idea was…
I really want Software Defined Networking (SDN), or something like it, to be the go-to approach for networking, but are we too tied to our idea of what SDN is for us to get there? The Definition Almost ten years ago in 2009, Kate Green coined the term Software-Defined Networking in an article describing the newly-created…
When it comes to networking specifically, software-defined networking is a model in which the use of programmability allows IT professionals to increase the performance and their ability to accurately monitor the network. This can be also seen in server environments as well. By harnessing the ability to program specific…
