Tom Nolle: Is There Anything to Virtual Networking?

We're hearing a lot about "virtual networking" with the Nicira and Xsago deals, but not all virtual networking approaches offer the same benefits, and these two early ones show just how different the missions and value proposition for enterprises can be.

Re: Virtual Networks and Windows Server 2012
It seems to me that it provides some of the same things that Nicira provides for VMware, which is the ability to create virtual networks on a per-application (or per-user, or both) basis and keep them separated.  I think that administration of cloud applications, for example, would be easier if you presumed that each application's components were assembled inside a virtual LAN (Hyper-V Virtual Switch) and that each then talked to the outside world through a virtual gateway.  I'm not sure how far Microsoft will go with this, though.  You almost need the same facilities that are implied in OpenStack's Quantum interface.

Virtual Networks and Windows Server 2012
Thanks Tom for your explanation of some of the issues  relevant in the wolrd of Virtual Networking.    What are your thoughts on the capabilities that the new Windows Server 2012  brings to the virtual networking table ?

Re: Enterprise Applicability
I think the jury is still out on this one, Zerox203.  Certainly the "supply side" of the technology at this point seems to be aimed more at multi-tenancy and thus to providers of service rather than to enterprise consumers.  However, from the cloud side at least some of the provisioning and even stack software (DevOps for the former and OpenStack Quantum for the latter, as examples) seem to be including a virtual network presumption.  I can see enterprises using virtual networking to augment security, for example.  Whether this will be promoted strongly by vendors and thus become a factor for buyers is hard to say, but I wouldn't be surprised!

Re: Virtual Networking
We're probably seeing the result of being in a promotion-and-marketing-driven world, Zerox203!  There's a lot of push on new technologies but the focus is on realizing something quickly, and that focus means we tend to neglect the strategic visions.

Virtual networking could create significant changes in how users consume services, and also in how applications join or control network relationships.  We should keep these issues in mind, I think.

Enterprise Applicability
I agree with you, Tom, in that I would lump this in to some degree with all kinds of other virtualization - it certainly has a place in the technology landscape of the future, but I don't know if it has a place in the business landscape of today. It's cool technology, and it's a realization of a lot of what we hope to accomplish with high-powered computing, but whether the applicability for it is there is up in the air.

Some Enterprises have a use for Virtual Networking, to be sure, but I trust that they already know who they are. Anybody on the fence can probably steer clear for the near future.

Re: Virtual Networking
Thanks for shedding some light on this topic, Tom! I hadn't even heard about either of these acquisitions yet, and while I don't exactly have my ear to the floor when it comes to Virtual Networking, it says something right there about the topic if a big buy like this doesn't make front page news.

Maybe it's just because it's not as 'sexy' as topics like Windows 8 or shiny new tablets, or maybe it's because there's legitimately less meat there. Either way, People don't seem all that excited about Virtual Networking in the short term, even with big news like this.
