The Virtualization Practice

DesktopVirtualization

Virtualizing Presentation Virtualization Workloads is increasingly seen as beneficial and more acceptable. As Citrix XenApp customers move into 2013 it is likely they’ll move more physical instances to virtual. To enhance RDS VM workloads with shared storage – Atlantis release ILIO for XenApp, the first solution designed specifically to accelerate provisioning, boot time and application response time

DesktopVirtualization

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.

The challenge for Citrix is to position their VDI portfolio effectively. At the very least there should be a standardised license plan and migration path from (or to) the grid and non-grid solutions. There is potential to remove the reduced functionality versions of XenDesktop. Most importantly – to have a license model that allows organisations to make a choice of technology that fits their need, not their size. Can Citrix FlexCast be truly flexible if it ignores the value that having a grid technology can bring not only to the SMB market – but to any sized enterprise?

VMware and Microsoft approach the Small to Medium companies quite differently, but which product to buy often depends on your business needs vs cost of the products. However, there needs to be at least one major distinction: SMB vs SME.

The Small to Medium Business (SMB) is quite a bit different than the growing number of Small to Medium Enterprises (SME), and VMware knows this does Microsoft or Citrix?

VMworld is clearly the largest dedicated virtualization conference, and yet from an Open Source perspective it is slightly disappointing because the VMware ecosystem naturally attracts proprietary software vendors, and also some of the more interesting activities in Open Source are through multi-vendor foundations which do not have the same marketing budgets as vendors themselves.

Nevertheless, there are a number of key Open Source players, and some interesting smaller players, represented at VMworld.

Cloud.com had lined itself up with Citrix by using only XenServer in the commercially-licensed version of its IaaS product, and now is being used by Citrix to ensure OpenStack supports XenServer (which it doesn’t at the moment), presumably to keep Red Hat’s KVM under control and VMware out. We’ve also been trawling through the available OpenStack documentation to understand why NASA thinks its cloud is more scalable than Eucalyptus. It seems to be all to do with how the state information is passed amongst the various servers that make up the system. GPL-based Open Core models break down when you move to multi-vendor foundations because the cross-licensing of IPR under GPL immediately infects the recipient codebase, and precludes commercial licensing of the resulting combined work. The result is that the GPL Open Core business model doesn’t work in the same way, and both Eucalyptus and Cloud.com cannot apply their current business model in these multi-vendor foundations. It is a big blow for Eucalyptus. They have turned their biggest potential customer into a massive and credible competitor, built in their own image (only – at least from a PR perspective – much more scalable).

In OpenStack the API is implemented in a separate service which translates external http requests into commands across the internal message bus, and so it looks (on the face of it) possible for someone (preferably Oracle) to implement the Oracle DMTF submission as a separable new API server module without disrupting the OpenStack architecture.

PhD Virtual has gained its second round of funding with investment from Citrix amongst others as discussed within our post News: esXpress is no more but what does this mean for XenServer? Up until this point it looked like Citrix was out of the server hypervisor wars and backing Microsoft’s Hyper-V play. Yet this looks on the surface like a basic shift to that direction. Yes, XenServer was placed into the OpenSource community and the latest improvements, such as the Open VSwitch integration and a new releases emphatically say that XenServer is alive and well and that its ecosystem is growing for that matter so is Hyper-V’s.

In a slightly strange “didn’t they already have Xen in the kernel” kind of way, Novell has certified Suse Linux Enterprise Server as a “perfect guest” running on Citrix XenServer, allowing joint support of the combined solution. The deal is asymmetric (it wouldn’t really make sense to run XenServer on SLES) but it reflects an open approach characteristic of the way Novell operates, in embracing the reality that customers will want to use one of a number of possible hypervisors, and that Novell has to get along with everyone. In return Novell is starting to push it’s PlateSpin Recon product through the Citrix channel.
