VMworld US 2015: Day 2 Recap

vmworld2015Welcome 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.

Another Missile Fired in the Cisco vs. VMware SDN War

Network VirtualizationYesterday 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%.

SDN: Sadly Defined Network

Network VirtualizationIn 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.  Continue reading SDN: Sadly Defined Network

vSphere Delay: Good Sign or Bad?

DataCenterVirtualizationVMware500x60Every VMworld conference is different, with a different tone and pace to it. At this year’s VMworld US, it felt like everything was evolutionary and very little was revolutionary. Icing that cake, VMware broke the decade-old trend of new vSphere announcements. Sure, the keynotes mentioned the next version, mostly by talking about some of the features it contains, but release dates, feature sets, and details were scarce, if available at all.

What Is Micro-Separation in NSX 6.1?

Network VirtualizationOne of the announcements of VMworld 2014 was a new version of NSX, which has been given a minor update to 6.1 from 6.0. I will delve into the nitty-gritty of what this release offers in a later post, but for now I’d like to draw your attention to a bit of marketese that VMware came up: “micro-segmentation.” Continue reading What Is Micro-Separation in NSX 6.1?
