IT virtualization

Everybody speaks about virtualization these days. It is considered to be a cherished objective of IT. However, most of corporations and technology suppliers share a misconception that IT virtualization is the same as computer virtualization, which is, for example, running multiple operating systems on a single server. In fact, computer virtualization is neither a versatile solution nor a complete process. On the contrary, IT virtualization is something of global scale. And it is largely influential to the entire IT infrastructure.

Virtualization is the technology that allows making computing resources autonomous and mutually independent. It should be applied to each single level of computing structure, starting from data center and ending at standalone PCs.

The purpose of virtualization is replacing rigid binding between different levels, such as between operating system (OS) and devices, between application and OS, between user interface and local computer. Instead, virtualization makes dependencies between mentioned elements relatively loose. This introduces new opportunities, and sometimes problems. For instance, by using virtualization of hardware (including server virtualization and desktop virtualization) we can make OS independent of hardware, which runs it. Likewise, virtualization of applications can perform similar separation of OS and applications being executed within it. In a similar fashion, virtualization of presentations is able to untie user interface from physical computer, which runs the application providing this interface. While you are working with an application on one machine, it can be controlled from another.

Separation of these levels makes for a much greater flexibility in every aspect of IT-infrastructure. More various ways of both hardware and software usage are introduced, as well as opportunity to replace components more easily. Owing to isolation of critical portions, systems become more protected. Many tasks of IT staff become simpler. Unsolved problems that irritated IT staff every day are gone.

Virtualization is a powerful tool of infrastructure transformation that affects all levels from data center to desktop workstations. It offers benefits such as faster application deployment; uninterrupted availability of systems, applications and data; minimizing difficulties connected with servers and desktops recovery or taking them offline for testing and development; lowering costs and improving flexibility of the entire environment. You can also see the list of server virtualization benefits.

Integral concept of IT virtualization
Evidence suggests that large-scale virtualization can offer considerable advantages. However, it also became clear that virtualization has its specific difficulties, for example the necessity of maintaining “the islands” of overgrown virtualized and physical assets. That’s why it is recommended to use time-proven tools in order to make the task of controlling the entire infrastructure and all associated processes simpler and faster. Transition to IT virtualization should be implemented in a way that won’t lead to consequences negating its advantages.

This integral approach at virtualization is not just a theory. This is reality for Microsoft Corporation and most of their customers. In order to bring all-round virtualization to life, the corporation has united resources of specialists, partners, products and solutions.

Integral approach at virtualization will aid organizations in advancement towards dynamical condition, making for enhanced flexibility of IT systems and simplicity of changes.
