The Virtualization Practice
Performance Management for Desktop Virtualization (VDI) and Presentation Virtualization (SBC)

Ovum’s research found that desktop virtualization currently represents approximately 15% of the business PC market. However, this figure is dominated by the Presentation Virtualization model (12%), typically used in call datacenter-type environments, and has been for the last 10 years. If PV/terminal services are excluded, the next generation of solutions aimed at CIOs, from the likes of Citrix, Quest and VMware, hold less then 3% of the market, showing that many CIOs are holding back from taking the plunge.

I was reading through a recent article about the new Java 7 release, which contradicts Oracle’s current support statement with respect to licensing. The License from Oracle exclusively states Java 7 is only supported on those hypervisors Oracle currently supports: Oracle VM, VirtualBox, Solaris Containers, and Solaris LDOMs except where noted. That last phrase is rather tricky, so where do we find such notes. Is the noted the support document stating that they support Oracle products within a VMware VM? Or is it somewhere else in the license? This leaves out all major hypervisors: Citrix, VMware, and Microsoft. If you cannot find a note saying things are supported, somewhere.

This implies quite a bit for the future of Java support within most PaaS environments being built today. In essence, they cannot upgrade to Java 7. Which means they may fall behind. This would impact OpenShift, Amazon, Google, CloudFoundry, SalesForce, and others.

With the announcement of vSphere 5.0, VMware has kept its word on only having VMware ESXi for the physical host operating system. This is the first release of vSphere with just VMware ESXi as an option. I must admit that I was not a big fan of the concept when it was introduced as an option in the 3.x days. I had a very slick automated process in place that was one of my pride and joys at the moment and VMware ESXi was just lagging behind in functionality compared to what I was able to do with VMware ESX. My attitude started to change with the release of VMware ESX 4.1 as presented in an earlier post and now that vSphere 5.0 is announced I must admit that I think VMware has gone about this process of a cutover to ESXi quite well and the functionality that is presented in this release is quite impressive.

VMware has done the right thing by taking care of their enterprise customers and making sure that they know that they can purchase vSphere 5 licenses under the terms of their existing ELA’s. The vast majority of smaller customers who run a small number of purchased applications are unlikely to be impacted by the new vRAM licensing, as their is probably plenty of vRAM headroom to take care of their needs. The issue is with customers who are not quite large enough to have an ELA, and who have sophisticated mixes of purchased and internally developed applications – and who are trying to push the density envelope in order to maximize their return from their investment in VMware. This customers are going to have to look at the new licensing in the above terms and make their own decisions.

The 7/7 Virtualization Security Podcast with Steve Kaplan, Vice President of INX’s Data Center Virtualization Practice and well known ROI/TCO expert within the virtualization and cloud space, joined us to talk about the ROI and TCO of virtualization and cloud security. We discussed someways to view virtualization and cloud security, but mostly the fact that many people may not think ROI or TCO even applies until a problem occurs and you need to rush in and find and fix the leak that lead to a break-in. In essence, the ROI of proper security tools is your entire business.

VMware – A Train with an Engine, 3 Boxcars, and a Caboose

VMware is already the most important, and with vSphere the best systems software vendor on the planet. This is true not only based upon the current success of the vSphere platform, but the quality of the long term strategies in place for vFabric, vCloud, and vCenter. With vSphere 5, VMware can ill afford distractions that detract from the momentum of the attack upon the remaining 60% that is not virtualized. The strategic investments in vFabric, vCloud, and vCenter then call into question of viability of having a desktop virtualization business (View) that is today in product and tomorrow in vision a minor subset of what Citrix is delivering and articulating.
