In just the last two months Gartner have published three documents that talk about the importance of Persistent Personalization, their term for a subset of User Environment Management (UEM). They have approached it from three different directions: One document looks at Persistent Personalization itself, one for hosted virtual desktops and one for client virtual desktops. As you would expect with three documents in such a short period of time there are some very solid pieces of information and some long shots. In this article I want to pull together the principal themes and clarify some of the points they make.
Out with the old in with the new
Organizations have been implementing VDI since around 2005 but the early implementations were all reliant on keeping a complete copy of the user’s image for each user. This meant that the use cases where it made sense to deliver desktops in this way were economically limited. Today organizations are implementing VDI through componentizing the image and then automatically delivering those components on demand allowing IT to standardize the components and hence reduce costs and improve service delivery for the broader user base. One of the critical components is the user environment which represents all user related information in the image and which is delivered into the standard components to give the user a productive and familiar experience.
Up to now there has been some debate on what the critical dates for the adoption of this new componentized model and hence VDI in general would be. Gartner’s take is that VDI is ready for task workers now and will be ready for deployment to a broad range of users in 2010, driven by the actions of vendors such as AppSense introducing functionality such as user installable applications to allow greater user freedom. They also see that the componentized model will drive the older single-image-per-user deployments obsolete by 2012.
Persistent Personalization (UEM)
Unsurprisingly Gartner see Persistent Personalization as critical for the success of desktop virtualization with some stages of its development being contingent on developments in UEM. In particular Gartner cite the capability for a user to be able to install applications and I would also point to improvements in the manageability of the platform.
In debates on technology it is critical to keep in mind the overall objective and so not get diverted into unproductive side alleys. The objective of desktop virtualization is to improve the manageability of the desktop platform and hence deliver a better service to corporate users at lower cost. The way that we will achieve this is by standardizing the components of the image and managing these components across the business and so achieving economies of scale. Consequently, key to reaching our goals is that we can manage the components effectively. This means being able to manage the delivery of the components but also manage within the components so that we have appropriate visibility and control into the components. We must not slip back into the unique and impenetrable image problem we have in current PCs, generally referred to as ‘the blob problem’. This means that manageability of the user environment is key so delivery can be done efficiently and so that any user problems can be isolated quickly and effectively.
And a new category: Workspace Virtualization
Within Persistent Personalization, itself a subset of User Environment Management, Gartner have introduced a new category called Workspace Virtualization to cover vendors such as RingCube, MokaFive and UniDesk. Some of these vendors are completely new, some have had offerings in different markets before but this is their first recognition as part of broader corporate desktop virtualization. Consequently it is worth thinking about how their technology could contribute to the goals of desktop virtualization.
Amongst the vendors with products the common theme is that they split the image stack in a different way to typical desktop virtualization. Rather than creating a division between operating system, applications and user environment they split purely on the basis of operating system and everything else.
This has the benefit of simplicity but does it address the problem we need to address and hence achieve our goals? The solutions in this category are very new to market and will undoubtedly mature over time but I have two concerns. Firstly, can these solutions manage the components of desktop virtualization so that we achieve economies of scale or are we going to find ourselves with an unmanageable blob per user, much as we have now? Secondly, can these solutions become more than a point solution for just a small proportion of users leading to another management tool which must also be managed? It is too early to tell with the solutions we see now and it will be interesting to see if this sub category can carve a niche for itself.
In conclusion it is great to see Gartner getting behind the importance of Persistent Personalization and its importance to desktop virtualization. Three papers in two months is recognition that Persistent Personalization and the larger category of user environment management is critical to the development of desktop virtualization. This will help the broader market understand the role of UEM in improving the overall management of corporate desktops and hence deliver better service for users at lower cost.
