Welcome to The Virtualization Practice’s week-long coverage of VMworld US 2015. Tune in all week for our daily recap of the major announcements and highlights from the world’s premier virtualization and cloud conference.
VMworld US 2015 continued in force yesterday, beginning with a long but powerful general session/keynote talk. Carl Eschenbach, VMware’s president and COO, set the stage for a slew of announcements around VMware’s “One Cloud, Any Application, Any Device” approach to computing and a seamless federation of all types of clouds, supporting both traditional and new cloud-native applications. A variety of VMware leaders joined him on stage to talk about the various aspects of these announcements and how they mesh with their overall strategy. While each of these areas could give rise a whole series of posts by themselves, I’ll summarize the major points.
Yesterday I was reading about Cisco’s fourth quarter earnings results, as you do when you are bored and waiting for the next episode of EastEnders to start—well, we all have to take a rest from SDN goodness every now and then. Now, this was interesting for two reasons. It was the last quarter under the leadership of big bad John Chambers and the first announced by new head honcho Chuck Robbins (sounds like a cross between a cage fighter and a liberal comedian). Firstly, congratulations are in order on the results—Cisco exceeded analysts’ predictions of $12.6 billion in revenue, with $12.8 billion and a per-share profit of 59 cents, up almost 4% over the previous year, and an overall year-over-year increase of 4%.

I was tinkering around with XenServer the other day. I know I can hear you saying “is that a thing?” Well, it is, but this is not what I am going to talk about today. Time for a tangent shift. I thought I would have a look for a third-party switch for XenServer, but it seems that XenServer is a third-rate citizen in this space, as there is no Cisco Nexus 1kV available for XenServer, even though Cisco previewed it at Citrix Synergy Barcelona in 2012.

Who knew Nokia was still a thing, after Microsoft bought it? Well, as it turns out, Microsoft only bought the Devices and Services division. Nokia still has a number of other divisions, including NSN (the network infrastructure division), HERE (maps and location-based services), and Advanced Technologies (a licensing and development arm). Microsoft has been paying Nokia a big wedge of cash over the last two years to license Nokia’s HERE services, and the contract extends for at least two more years. For Nokia, getting out of the phone market was an astute move. It had lost the handset war and had moved from a position of dominance to being an also-ran. Its high-end Lumia phones, while nice, weren’t delivering an adequate return on R&D investment when going head to head with the now-dominant Apple and Samsung handsets.

We have all drunk the Kool-Aid. Software-defined networking (SDN), network functions virtualization (NFV), or both will save the world. They decouple us from the shackles of legacy networks to allow a utopia of business-driven requirements to freely flow, delivering value and freeing the network, application, storage, and infrastructure teams to have weekends off and time with their families.

In virtual and cloud environments, network traffic often flows into a virtualization, then back out, forwarded to another device, usually security, before it re-enters the virtual environment. I call this a “sadly defined network,” not software-defined. Many of my colleagues claim that this is not true. They say that an SDN keeps east-west traffic within the hypervisor and that north-south would not need to do this. I disagree. This will happen when bad design is implemented in virtual and physical security. “Ah!” some will say, “this is solved by micro-segmentation,” but that is not always true, either.
