The Virtualization Practice

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. ...
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.

DesktopVirtualization

Can you use Desktop Virtualization in your organization to improve IT delivery? Desktop Virtualization, as a concept, is straightforward – separate the desktop environment from the physical machine. This gives you benefits in terms of speed of delivery, how you can provide access to mobile and remote workers, how you can ensure security and compliance.

Is virtualizing Citrix XenApp a waste of time and effort? In spite of the hardware abstraction allowing easier image management and OS upgrades; in spite of options for higher availability and faster recovery, even fail-over; in spite of enabling silo consolidation; in spite of enabling managing user capacity on servers – especially for x32 environments, but also x64; … what could virtualization of your Presentation Virtualization environment possibly do for you?

The Freemium sales model is a business model innovation best suited to inexpensive products that are very easily understood (and therefore not very new or very different) and that solve an obvious problem in a manner that is more convenient for the customer to acquire and implement. There are not many new virtualization and cloud technology companies who set out to produce undifferentiated products which suggests that a general application of the Freemium model to startups in our ecosystem is ill advised. Enterprise customers should pay great attention to products that are being marketing in this manner to ensure that they do not end up growing the use of something that was purchased in a tactical manner into a strategic use case.

VMware’s 5 Businesses and the “New Stack”

VMware dominates the enterprise virtualization platform business with vSphere, and is poised to create a vSphere compatible public cloud ecosystem around vCloud. Layering Management software on top of these platforms is a logical progression up the value stack, as is layering an applications platform (vFabric) on top of vSphere and vCloud. VMware’s end user computing strategy seems to be too tied to VDI to be able to break out of the fundamental limitations associated with this approach, and will likely leave the larger question of how to manage the next generation desktop to the previously mentioned startups and perhaps Symantec.

VMware has said that is it committed to its Desktop Virtualization Strategy but VMWare’s commitment to VDI as the only solution is going to mean that unless you are only going to deploy VDI you’ll likely consider another vendor to help you achieve your goal.
There are two desires which are fundamentally in conflict, and addressing this conflict is the biggest opportunity in desktop computing. Can you manage the demand for users to have effective IT at their fingertips while controlling access and costs from the centre?
