Both Microsoft and VMware have revamped their product suites, and therefore their licensing, once more. As always, how you buy will dictate how you license. It has taken a bit of time for all the revamped information to percolate through to each corporate site and for all the issues to be addressed. As we did before, let us look at licensing. We will look first at the old model of Hyper-V vs VMware vSphere vs Citrix Xen vs RedHat KVM. Then, in a follow-on article, we will look at the new cloud suite models.

Piston Cloud Computing raised a few eyebrows on Tuesday with the announcement that it was extending its Piston Enterprise OS (PentOS) to provide a platform for hosting virtual desktops (VDI) through an exclusive licensing deal with Toronto-based Gridcentric for its innovative Virtual Memory Streaming (VMS) technology.
Toronto based start-up Gridcentric, is developing a technology that it refers to as Virtual Memory Streaming that has the potential to reshape the economics of VDI, and deliver the holy Grail of a VDI desktop for less than the price of a PC. It should come as no surprise to hear that the single biggest performance challenge that all large VDI environments face is the boot storm. The Windows boot and logon processes generate many times more IOPS traffic than steady-state user operations. So much so that in poorly specified systems a boot storm will overload the storage infrastructure, starving Windows of resources and leading to excessively long start-up times.
Atlantis rightly herald ILIO for XenApp, the first solution designed specifically to accelerate provisioning, boot time and application response time for virtualized Citrix XenApp deployments into a market that some would say is quite specific.
Atlantis have evidenced reducing provisioning time, improving the user experience and reducing the amount of storage required by up to 90% for Terminal Services/Microsoft RDS workloads.
Way back in the day the Atlantis ILIO offering had some difficulties, but recent releases for both ESX and Hyper-V have seen ILIO become a common component in VDI delivery. Yet, a Presentation Virtualisation (PV) solution like Citrix XenApp is a different environment, often managed and licensed in a different way: and there is ever the question – should you virtualize XenApp? The claims on performance and density when Atlantis ILIO for XenApp is used are compelling, so will this release give a fresh impetus to virtualising RDS workloads and help with the migration to Citrix XenApp 6.5?
Dell has joined the the highly competitive and technically diversified single box desktop virtualization market in partnership with Citrix to package VDI-in-a-Box as a virtual appliance. The somewhat awkwardly named Dell “DVS Simplified 1010” appliance is built on the Dell PowerEdge R710 rack server that comes pre-installed with Citrix XenServer 5.6 and VDI-in-a-Box 5.0.
Dell already offers VMware View as part of its Flexible Client Solutions offering that can be ordered online as part of a standard server package. However, the simplified in everything but name, DVS Simplified 1010 goes considerably further delivering it as a dedicated plug-and-play appliance.
Just in time for the major desktop virtualisation event known as VMworld, Citrix have announced the release of XenDesktop 5.5 as part of their desktop virtualisation trifecta. This latest release is truly an advanced and feature rich VDI solution, but it is not the only VDI offering Citrix has.
