Virtual Desktop Infrastructure

Pure Siebenmorgen COC AG makes a comparison of the respective benefits from Burghausen, 07.05.2012 – triggered by the proliferation of virtualization technologies, companies are increasingly faced with the question whether they should focus in its strategic orientation on Terminal Services (TS) or virtual desktop infrastructure (VDI). The first mentioned technology are the applications on a Terminal Server and do not need to be installed on the local computer of the user. In a VDI environment, however, each user has an individual desktop, including the operating system and all required applications. Pure Siebenmorgen, virtualization at the COC AG, head of the Department has made a comparison of the two approaches with respect to the benefits: users flexibility: environment standard applications can be used for comfortable and easily scalable in a TS. VDI offer the user a total more setting possibilities and performance. Especially developers and users of several Slightly more virtual machines running any operating system have let VDI an advantage, given that there create operating systems.

Administration effort: The lower administration overhead is Terminal Services. Even at medium and high number of users, the cost is manageable, while the Administration in the case of VDI with increasing number of users is expensive and complex. But considering the definition of critical applications, clearly the virtual alternative scores. A high utilization of memory and compute-intensive applications work within a virtual machine and have no influence on the stability and integrity of other desktops. The Terminal Server solution requires a sophisticated and thus also extensive application in such cases.

Cost: VDI requires a higher capacity and higher storage capacities, as well as central storage as opposed to the Terminal Server technology. This affects the cost of server hardware. And this has the following background: at any virtual machine operating system and local applications must be installed, while the resources at the Terminal approach. Licensing: cost differences also arise in licensing operating systems and additional programs.
