virtuelizacije

Virtualizacija refers to the creation of a virtual version of something, such as an operating system, server, storage device, or network resources. This is achieved through software called a hypervisor. The hypervisor allows multiple virtual machines (VMs) to run on a single physical piece of hardware. Each VM operates independently, with its own operating system and applications, as if it were a separate physical machine.

The primary benefit of virtualizacija is increased efficiency and resource utilization. Instead of dedicating a physical server to a single task, multiple virtual servers can be consolidated onto one. This leads to reduced hardware costs, lower power consumption, and less physical space requirements. Virtualizacija also enhances flexibility and scalability. New virtual machines can be created and deployed quickly, allowing organizations to adapt to changing demands. Disaster recovery and business continuity are also improved, as VMs can be easily backed up, migrated, and restored.

Different types of virtualizacija exist, including server virtualizacija, desktop virtualizacija, network virtualizacija, and storage virtualizacija. Server virtualizacija is the most common, allowing multiple operating systems to run on a single server. Desktop virtualizacija separates the desktop environment from the physical hardware, enabling users to access their desktops from various devices. Network virtualizacija abstracts network resources, creating virtual networks that operate independently of the underlying physical infrastructure. Storage virtualizacija pools physical storage from multiple devices into a single logical storage pool.
