Presentation Virtualization

Presentation Virtualization is an application delivery method that delivers users desktops and applications from a shared server, AKA server based computing. This method of delivering applications to users focuses upon running an instance of each Windows desktop operating system application i.e., Word, Excel, PowerPoint and Office for each user on a shared instance of a Windows Server operating system. (Read More)

The most popular product in this category is Citrix XenApp and its predecessors which include Citrix Presentation Server, and Citrix MetaFrame. In the 6.0 releases of its products, Citrix bundled XenApp into XenDesktop. In the 7.0 releases of its products, XenApp has been made available separately again. Microsoft also has a product in this category – Microsoft Remote Desktop Services, but this offering is mostly used in smaller implementations that do not require the enterprise class features that Citrix offers.

Citrix announces IaaS Project Olympus built on OpenStack

I like OpenStack (the Open Source IaaS Cloud Platform intiative), partly because of the model of open innovation and permissive licencing (which reminds me of my time at Eclipse) and partly because even within the existing governance model (which I have criticised) there is the opportunity for different agendas to surface and to drive the project in different directions and this diversity makes an analyst’s life more interesting.

One of the most intriguing names that has hitherto been at the periphery of the OpenStack initiative is Citrix. Up until last week, Citrix’s contribution was to ensure OpenStack ran on XenServer, something which I’m sure Citrix cares about, but perhaps wasn’t top of the list of requirements for the rest of the world. However, this week at it’s Synergy event, Citrix made some more sigificant announcements about Project Olympus, through which it aims to provide (in collaboration with Dell and Rackspace) a route to commercial exploitation of the OpenStack codebase.

Citrix License RES Reverse Seamless Windows

RES Software confirmed today that it is has signed an agreement with Citrix to license RES’ reverse seamless Windows technology.

Citrix confirmed that while it has a license to use RES Virtual Desktop Extender (VDX) it does not intend to integrate RES’ VDX solution into it’s own products. Instead it has taken out the license to allow it to implement its own reverse seamless solution without running afoul of the patent that RES holds on reverse seamless Windows.

VDI Printing. Is it the Nemesis it was for Terminal Services? Part II

In 1436 Johannes Gutenberg collaborated with a gem cutter and a paper mill owner to seek seed funding from venture capitalists to began work on the ‘Printing Press’.  Their invention began the ‘Print Revolution’ driving a wider spread of knowledge and new understanding, innovation and industry. Printing is so fundamental that it is often overlooked as an IT service when migrating to virtualised desktops. In Part I, we considered issues with distributed printing and what printing functions you should consider for your desktop architecture.

VDI Printing. Is it the Nemesis it was with Presentation Virtualisation? If so would client hypervisors help, or is it that traditional desktops delivery is still the best method? In Part II we’ll consider the core printing options for the likes of Citrix XenDesktop, Microsoft RDS, Quest vWorkspace and VMware View; and how they match to our printing considerations. Do you still need third party products to make your print solution effective? We’ll take an overview of solutions from ThinPrint, triCerat and UniPrint to help find out.

Hopefully you can use this knowledge to avoid any user revolution to your hosted desktop implementation, and instead, press on to get the best printing solution for your organisation.

VDI Printing. Is it the Nemesis it was for Terminal Services? Part I

All the News That’s Fit to Print” is the motto of the The New York Times . Despite a proliferation of devices that allow you to take content with you wherever you go, despite e-mail, despite services like LinkedIn, Podio and Twitter there is still a driving demand  to generate hard copies of documents.

Printing is so common and fundamental that it is often overlooked as an IT service when migrating to virtualised desktops. How do your users connect to the printers they have? In fact, what printers do they use? What are the printer drivers and settings that are common or unique? Continue reading VDI Printing. Is it the Nemesis it was for Terminal Services? Part I

What to look for in a mobile OS if you are serious about desktop virtualization

The phenomenal growth of the tablet market has left many industry analysts scrambling to reassess sales forecasts for both tablets and PCs.  Last week Gartner was forced to acknowledge that its previous forecasts were way off the mark when it issued a revised 2011 sales forecast that reduced its November 2011 PC sales growth estimate by a staggering 25%. Gartner research director, Ranjit Atwal, said his company had not fully appreciated the impact that tablet devices were having on the market, and the new figures “reflect marked reductions in expected near-term unit growth based on expectations of weaker consumer demand, due in no small part to growing user interest in media tablets such as the iPad.” Given that this is the same Gartner that in September 2010 instructed CIOs everywhere to go out and buy iPads, it shows just how badly it underestimated the tablet’s impact on the PC market. As tablet sales (and for the moment we can read that as being almost exclusively iPad sales) continue to cut in to sales of PCs and laptops, PC manufacturers are under pressure to offer their own alternatives and IT organizations are under similar pressure to provide ways to integrate tablets into their core service offerings.

Licensing VDI for Microsoft Desktops – is it rocket science?

On Feb 24, the US Space shuttle Discovery took off from Kennedy Space Centre for its final mission. At its launch, Discovery will have completed 38 voyages and traveled 230 million kilometers.  In 1970 approximately 200,000 miles from Earth in a damaged spacecraft, new protocols were  designed and new equipment re-created from spare parts in order to bring astronauts safely back to earth. In 1961 the first man entered space and come 1969, man was walking on the moon. Continue reading Licensing VDI for Microsoft Desktops – is it rocket science?
