These changing combinations or computing processes result from communication between the user, software application, operating system and the underlying hardware. Computing processes involve the changing combination of these states or binary digits. These digits can also be represented as the transistor states within computer processors: On and Off states. How Virtualization WorksĪt the machine level, every computing operation is represented in binary digits, 1’s and 0’s. This capability translates into easy, low-cost, manageable and optimized server operations. As a result, virtualization lets organizations operate hundreds of servers in the same way they operate a few server machines. The hardware resources are logically distributed between software applications that can consume the computing power in virtual infrastructure environments without having to depend on the physical hardware components. It is the science of emulating a hardware functionality within a software system – creating a virtual version of a physical systems such as hardware platforms, storage and network resources. The term Virtualization is described as the decoupling of a service request or system resource from the underlying physical infrastructure that powers the service. To address this problem, the Virtualization model of computing was invented. The resulting infrastructure inflexibility and high cost of operating infrastructure resources necessitated a solution where the software application layer could be decoupled from the underlying hardware infrastructure. Installing a piece of hardware to boost performance required users to shut down the entire system and when the systems were running, most machines could operate only a single application at a time to avoid system conflicts. The hardware resources and software systems were tightly coupled. There used to be a single operating system image for every machine. Original mainframe OS that enabled these capabilities made the overall system too complex and underoptimized. A resource sharing system was required for multiple users to perform multiple batch jobs simultaneously. Virtualization has its origins in the mid-1960s when users relied on slow and inefficient batch processing and required expensive mainframe machines to speed up the process. This week, let’s look at the world of virtualization and where it can and will benefit you. Virtualization technologies are used for several different DC functions, including some that you may not even think of as virtualized features. It’s not uncommon for example, for a single Intel or IBM POWER system to host several different virtual machines using the Windows, Linux, IBM i, or AIX operating systems, dramatically decreasing the physical hardware space needed in your Data Center (DC).īut it’s a mistake to think of virtualization only in terms of virtual machines. Many people think of virtualization only in terms of virtual machines (VMs), where one physical machine hosts many VMs running different operating system implementations. IT virtualization is the creation of a virtual-rather than a physical-version of an IT device or resource.
