Manageability: One of the major concerns of an organization is management of the desktop infrastructure. This is because the core component of a desktop infrastructure is the personal computer (PC) hardware, which continues to evolve rapidly. Organizations are forced to deal with a variety of hardware models, face complicated PC refresh cycles, and handle support problems related to PC hardware incompatibilities with applications. This requires that IT personnel spend most of their time supporting the existing environments instead of deploying new technology. Virtual desktops are far easier to maintain than traditional PCs. Because of the unique characteristics of VMs, they provide simple flexibility to the user when accessing. Since the application physically resides in the data center, it is much simpler to patch/fix/repair applications, provision new users, remove users, and migrate the applications to new OSs, new computers, and even new data centers.
Virtualization
Published in Kirk Hausman, Sustainable Enterprise Architecture, 2011
A virtualized desktop environment can allow continued use of legacy desktop hardware that is no longer able to run the most current applications, by allowing the older hardware to function as a thin or thick client for a remote virtual desktop running on hardware with sufficient resources to support more recent applications and services. Extending the life cycle of individual systems this way reduces procurement costs and the environmental impact of computer manufacturing and disposal processes.
Infrastructure as a Service

Regardless of the model, there are three benefits that just about every organization is looking for when they move to virtual desktops: simplified deployment, greater security, and reduced support costs. The cost and simplicity issues are beyond the scope of this book. The real question for us to examine here is whether—and how—virtual desktops are more or less secure than traditional desktop clients. The answer to the question, as with so much of life, is, “yes—and no.”
Efficient resource management techniques in cloud computing environment: a review and discussion

Virtualization technique has become popular in IT industry as a software-based solution to build shared hardware infrastructures [21]. Virtualization technique is a framework to divide the resources of a computer into execution environments to make the physical machine to be productive for the resource utilization and resource management. The main importance of virtualization technique is that it supports migration of VMs from existing host machine to other physical machines (in hosts migration or between hosts migration) [22]. Virtualization technology brought technical basis in cloud computing. There exists different kind of virtualization technology used in cloud computing such as storage virtualization, server virtualization, network virtualization, client virtualization, operation framework virtualization [23]. The network virtualization is based on virtualized network switch technology commonly known as vSwitch. Client Virtualization is a client virtualization technology based on creating a client desktop as a VM called VDI (virtual desktop infrastructure). A VDI uses rack-based servers distributed across the data center (DC) with a top of rack (ToR) switches at the network edge.
