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.

Is Windows 2012 Remote Desktop Session Host better than Citrix XenApp?

PresentationVirtualizationIs Windows 2012 Remote Desktop Session Host (RDSH) better than Citrix XenApp? Citrix XenApp 6.5 is a market-leading product. Citrix XenApp may well be the first product businesses consider when deploying applications or desktops from a centralised service. Windows 2012 is very new. Windows 2012 RDSH, as a new service, doesn’t have the same number of partners or administrators with detailed experience.

Still, it’s a very good question.

It’s a very good question because Microsoft has worked hard to ensure that RDSH is a solution viable not only for large enterprises, but small and medium scale businesses and not-for-profit organizations, as well. Windows 2012 RDSH builds on a mature technology, a technology that is the most-deployed centralized desktop virtualization solution.

Yet, are you going to end up reading this article and get to an “it depends” answer?  Let’s see.

Microsoft Windows 2012 RDSH vs Citrix XenApp – PV to get its own Murderball?

PresentationVirtualizationThere is a pervasive question for Presentation Virtualisation using Remote Desktop Session Host services (RDSH) and that is  :-

if I’m already paying for RDS CALs and running the base OS, why do I need other stuff?

Where stuff is, typically, Citrix XenApp. With the release of Windows 2012 and the updates to RDSH do you still need Citrix XenApp?

I was introduced to many new sports over the summer and one sport that stuck in the mind, not only for it sheer fury and skill, was wheelchair rugby (or Quad rugby). Or as the Canadian inventors, named it – Murderball.

A key elements of the sport – it is a fast and very competitive exchange.

Your ball you say? I think not.

Sneaking into August, like an American multi-gold medallist back from a celebratory night out on the champagne, Microsoft’s Windows 2012 boasts a wide array of new features. Hyper-V’s improvement are worthy of a post in themselves: live migration, teaming of 32 NICs, thin provisioning, dynamic memory. For now, we’ll focus on the updates to Remote Desktop Service’s Session Host updates.

With new and improved functions in Remote Desktop Services in Windows 2012, how competitive is the exchange? Is it worth murdering a ball for?

Teradici to knock out XenApp – or receive a bloody nose like everyone else?

DesktopVirtualizationWe’ve joined many in heralding Teradici RDSH solution’s VMworld announcement. Weaving sweetly around the fact that the actual release won’t be until at least the end of 2012, it is only right that to take a quick jab at the fact v1.0 will be feature lite in comparison to the heavyweight Grand Old Man of desktop virtualisation Citrix XenApp until well into 2013.

In PCoIP Teradici have a remote protocol: but Citirx’s XenApp application is more than an ICA  protocol extension for Microsoft’s Remote Desktop Session Host (RDSH). What can RDSH bring to a virtualised desktop environment? Will protocol support to RDSH be enough for Teradici to deliver a service that can complement an existing VMware View environment?

OnLive – bad management, or an example of DaaS immaturity?

DesktopVirtualizationOnLive isn’t. As already mentioned, the cloud gaming provider and desktop service provider has ceased to be. Poor budgeting; ridiculous hardware-to-user ratios; low take-up. Quite simply – more money out than in. Ergo, failure  a simple question of finance and poor management.

Nothing to learn here, move on?

Or, can OnLive’s demise give a wider lesson to enterprises? Sure, OnLive were predominantly a games focused company. Yet, the delivery and development of games has driven a lot of technology advances that enterprises use in desktop delivery today: Microsoft’s App-V is software at the heart of desktop virtualisation and was a gaming technology back in the day. Moreover, the concept of any-device access is inherent in range of marketing material from virtual desktop vendors and service providers and also key to pushing game titles to consumers.

But for the better financial planning and an understanding of Microsoft licensing, would OnLive have succeeded? Were they doomed to failure to failure before the off?

What are the key questions you should be looking to have answered from your DaaS service provider?

VDI Security – better than physical desktops?

VirtualizationSecurityAre virtualised desktops – be they hosted desktops (VDI) or session desktops (RDSH)  more secure than physical?  We’ve questioned before the benefits of a virtual desktop infrastructure with respect to security. Is VDI secure? Is VDI inherently more secure than “traditional desktops”? In our article Virtual Desktop Security? Are They Secure? We considered VDI vendor claims that there are several big virtual desktop security wins:
