To address the increasing cost and complexity of managing dynamic IT environments organizations are trying to understand how to adopt virtualization technologies. The value proposition and “killer app” are quite clear in the data center, however less attention has been given to the opportunities for endpoint virtualization. Even though there are multiple methods to address client-side virtualization; hosted virtual desktops (HVD), bare-metal hypervisors, local and streaming virtual workspaces and a range of options that layer on top of and between them all, such as application virtualization, portable personalities, and virtual composite desktops, there is still a tremendous amount of confusion and even more misconceptions about the benefits of client-side virtualization than with server virtualization. The major architectural flaw in almost all of these solutions is they remain very back end and infrastructural heavy, which reduces the benefit of cost-reduction and lower complexity.
Unlike server virtualization, which drove adoption from the bottom up, that is from the hypervisor and then through the other stacks, adoption of endpoint virtualization technologies is moving top down, that is starting with single applications within an existing OS. Application virtualization adoption will accelerate over the next 12-18 months with Gartner life cycle management analyst suggesting that it will be included in the majority of PC life cycle RFP’s in 2010 and beyond. Workspace/Desktop virtualization will follow over the next 24-36 months, as will the endpoint virtualization infrastructures. The adoption of both workspace/desktop and endpoint virtualization infrastructure will align with organizations desktop refresh cycles. Considering the average is between 3-5 years and considering that many are looking at desktop refresh to support Vista, although it probably only has about a 10% market adoption, and Windows 7, it is conceivable that we will begin seeing accelerated adoption of desktop and infrastructure virtualization over the next 24-36 months as organizations rethink their current systems management processes and technologies.
Let’s look at the 4 client/desktop virtualization models I believe will become the most prevalent over the next 3-5 years… Continue reading
