How does virtualization technology work?

Virtualization technology works by creating a software-based virtual layer between the computer's hardware and the operating system. This layer, known as a hypervisor, allows multiple virtual machines (VMs) to run simultaneously on a single physical server or computer. Each VM operates independently, with its own operating system and applications, but shares the underlying physical resources like CPU, memory, and storage. The hypervisor manages and allocates these resources to each VM as needed. This allows for efficient utilization of hardware resources and enables businesses to consolidate multiple physical servers into fewer virtualized servers, reducing costs, and optimizing resource usage. Virtual machines can be easily created, modified, or moved between physical servers, providing flexibility, scalability, and improved system availability and disaster recovery capabilities.
