To ensure that your datacenters are running optimally, the physical servers must be maintained well so that they perform to their fullest. However, maintaining a server also requires a lot of time and resources, and operations that usually are very costly.

A virtual machine, which is an isolated software and behaves exactly like a physical computer, can do lot more than a physical machine at only a fraction of the resources and costs involved. For instance, a virtual machine can run its own operating system and applications, and includes the same computer components such as motherboard, VGA card, network card controller, etc. They are completely compatible with all standard x86 operating systems, applications and device drivers, and can be used to run all the same software that you would normally run on a physical x86 computer.

In other words, according to Iristel, there is, in fact, no difference between a virtual machine and a physical one, as far as the operating systems, applications or other computers on the network are concerned. A virtual machine is perceived the same way as the physical machine even though it is composed entirely of software, contains no hardware in any way and has its own virtual (software-based) CPU, RAM hard disk and network interface card (NIC (News - Alert)), explains Iristel.

According to Iristel, some key benefits of virtual machines over physical ones include isolation, no collocation facility required, encapsulation, flexibility and efficiency.

Plus, says Iristel, the x86 based computer hardware was designed to run a single operating system and a single application, leaving most machines underutilized. On the other hand, virtualization enables running several virtual machines on a single hardware, with each virtual machine sharing the same resources across multiple environments. Additionally, each virtual machine can run different operating systems and multiple applications on the same physical computer.

To effectively serve this industry, Iristel has created fully functional virtual machines running their own operating system and applications by using specialized software. According to Iristel, virtualization is done by inserting a thin layer of software directly on the computer hardware or on a host operating system. It contains a virtual machine monitor or “hypervisor” that allocates hardware resources dynamically and transparently, allowing the multiple operating systems to run concurrently on a single physical computer and share hardware resources with each other, states Iristel.
