The Virtualization Practice

The Virtualization Practice’s Presentation Virtualization Comparison Whitepaper discusses PV in relation to business’ application and desktop delivery needs. This updated release adds Aqua Connect’s Terminal Services for Mac Series 3 to those products from Citrix Xenapp, Ericom’s PowerTerm WebConnect RemoteView, Geniut’s ThinWorx, GraphOn’s Go-Global, Microsoft’s Remote Desktop Services, Propalms’ TSE, Quest’s vWorkspace, Systancia’s AppliDis Fusion and 2x ApplicationServer.

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.

Whilst I have been away on vacation, something fairly interesting has happened in the area of Open Source initiatives for Infrastructure as a Service in the form of a new initiative from NASA and Rackspace called OpenStack. You may remember in our last post in this area, we noted that there was a proliferation of offerings in the IaaS space, and it was in the customer’s best interest for there to be effective migrateability (or even mix and match) amongst public and/or private clouds. However, the API standards to support interoperability are proving elusive.

Virtual Computer recently announced the availability of their NxTop product for free for up to five users. NxTop combines centralized virtual desktop management with a “bare-metal” client-hypervisor to make managing many desktops as easy as managing one. But, you may ask, what can a client side hypervisor do for me? The answer – solutions such as Virtual Computer’s NxTop can be utilized to effectively manage your desktop environment, provided they have a functional management interface. That said, bear in mind this is a developing technology, but it is a technology that offers you the opportunity to manage your desktops with virtualization without the larger infrastructure requirements of VDI but that doesn’t mean to say it wholly replaces SBC solutions: but it is a useful option to consider.

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.

If your organisation has remote users – consider that the impact of centralisation on their desktop experience can be very different: and not always in a happy way. Citrix’s ICA protocol has been joined by the likes of Quest’s vWorkspace with EOP Xtream, or Ericom Blaze. There are a number of hardware solutions for WAN optimisation with the likes of Expand Networks focusing specifically on solutions to support VDI implementations. Don’t allow poor network performance and user experience to sabotage your desktop virtualization project.

Citrix has released XenApp 6 which finally provides support for Microsoft Windows Server 2008 R2 – what is available in this new release for your business. Besides R2 support, what does XenApp 6 offer your business, what WOW factors are provided to help justify the cost of using XenApp6 to springboard your x64 Presentation Virtualization implementation – be that a new implementation, or a migration from your existing environment.
