VMware pioneered the term “software-defined data center” (SDDC) as a way to refer to the virtualization of all of the hardware in the data center, not just servers. As useful as SDDC is, though, I think the phrase “data center” inherently narrows the view to a singular installation – a data center.
Modern networks, however, can span multiple owned data centers (and closets or “edge data centers”) across the globe, as well as colocation and cloud resources. Over-used as the acronym “SDN” may be, the software-defined network is still our real goal – a coherent network where location is no longer a limiting factor, in which servers, storage, switches and even the physical connectivity between devices are virtualized and centrally orchestrated via software from anywhere in the world.
VMware’s guest blog on MSPmentor is what got me started on the theme for this week’s post. They discuss how to achieve a software-defined data center, which they define as one where all hardware is managed via software, to enable more agility and ease of scaling. They identify 3 main ways to get there: building your own, using converged infrastructure, or leveraging hyper-converged infrastructure. It’s a good article, as far as it goes, but it doesn’t go into the question of multiple locations, colocation, or hybrid structures integrating the cloud.
Data Center Knowledge | Tim Kittila maps out the process and some of the decisions involved in both identifying the role colocation should play in your data center strategy and how to select a provider which will fulfill that role effectively.
Looking out at the colocation horizon, Fiber Mountain’s CrossCage Plus has a role to play in making it easier than ever to “software-define” your collocated equipment, integrating it seamlessly into your network and simplifying the delivery of services. Can you imagine a colocation provider offering point and click cross connects to their tenants? That’s the CrossCage Plus vision.
Opensource.com | Jeff Gehlbach discusses the history and future of NMS (network management system) platforms, and their intersection with the new challenges and opportunities of software defined networks. (Including a new-to-me reference to the idea of treating devices in the network less like pets and more like cattle!)
That’s all for this week! But before you go, have you had a chance to check out the Agile Digital Transformation Roadmap poster from Intellyx? Click here to download the full-sized PDF.
