Virtualizálása

Virtualizálása refers to the process of creating a virtual version of something, typically a computer hardware platform, operating system, storage device, or network resource. This virtual version behaves in the same way as the original physical resource. The core technology behind virtualizálása is virtualization software, often called a hypervisor.

A hypervisor allows multiple operating systems to run on a single physical machine. Each operating system, known as a guest operating system, operates in its own isolated environment, believing it has exclusive access to the underlying hardware. This isolation is achieved by the hypervisor managing and allocating the physical resources such as CPU, memory, storage, and network interfaces to each guest.

The benefits of virtualizálása are numerous. It enhances hardware utilization by allowing several virtual machines to share a single physical server, thereby reducing the need for multiple physical machines and their associated costs for power, cooling, and maintenance. It also provides flexibility and agility, enabling rapid deployment of new systems, easy migration of workloads, and improved disaster recovery capabilities. Furthermore, it simplifies testing and development by providing isolated environments for experimentation without affecting production systems. Virtualizálása is a foundational technology for cloud computing and modern data centers.
