Irwin emc hours1/19/2024 Improvements to thin-client virtualisation and remote display protocol technology have also enabled a new generation of virtual applications to run efficiently on devices other than desktop PCs for the first time. "The key thing driving the adoption of thin clients now is the pick-up in desktop virtualisation, a move to centralisation, and delivering IT-as-a-service as a way of bringing the desktop PC into the data centre," says Irwin. While the drivers for the adoption of desktop virtualisation technology are the same as ever, IT departments - and end-users familiar with virtualisation and cloud-hosted service models that deliver on-demand compute resources, workloads and applications in the form of infrastructure as a service (IaaS) and software as a service (SaaS) - now seem more confident in adopting the desktop as a service (DaaS) model as well. Citrix product manager Patrick Irwin says: "You don't need to go and get something new out of the cupboard, or have people rushing around trying to fix things." New applications Scaled-down hardware options on thin clients and other end-point hosting devices also mean fewer fixes or upgrades to physical components. With desktops virtualised alongside servers in the data centre, back-ups become easier to run with operating system and application upgrades, and patch management simpler to perform. Putting capital expenditure to one side, ongoing savings appear genuinely significant from reduced hardware and software maintenance and management overheads. These include whether IT departments choose to procure thin-client hardware or push virtual desktops on to legacy desktop devices, and what other upgrades need to be made in the back-end servers and'local' 'and wide-area networks. Where, then, does that leave the thin end of the market? Adoption driversĪs with all technology, cost and return-on-investment, arguments for thin-client and virtual-desktop deployment are often misleading and depend on many variables. While organisations buy fewer standard PCs and laptops for their desktops, the rise of enterprise mobility has meant that the thin-client market has not taken over the desktop computing requirement as some predicted. Market analyst Gartner forecast that 60 per cent of companies worldwide will have some form of VDI deployed by the end of 2012, up from 10 per cent in 2008, with vendors pushing VDI, thin client and terminal services capabilities hard, including Citrix, Dell (which purchased thin-client specialist Wyse in April 2012), EMC, Hewlett-Packard (HP), and Microsoft. The thin-client concept has been around for at least a decade in its current manifestation, and the advent of server virtualisation should in theory go hand-in-hand with the enterprise computing model. The distinction between all three approaches is becoming less well-defined, particularly in recent years as hybrid desktop virtualisation platforms, which split the workload between cloud-hosted virtual servers and local devices, have emerged. You'll even see the old terminal services model whereby the end device simply provides a window into applications and services that run entirely elsewhere on a data-centre server or mainframe computer, or other remotely located central-processing platform. Or you may see thin clients, essentially stripped-down versions of the traditional desktop PC, which can host either complete virtual desktop images or only specific applications and trimmed down profiles. You may see virtual images of an entire desktop complete with operating system, applications, and user profile delivered to various devices via virtual desktop infrastructure (VDI) initiatives. The virtual desktop PC can be delivered in many forms.
