A hypervisor, also known as a virtual machine monitor (VMM), is a software layer that enables the creation and management of virtual machines (VMs). It allows multiple operating systems to run concurrently on a single physical machine by abstracting the underlying hardware resources. Hypervisors can be categorized into two main types: Type 1 and Type 2.

Type 1 hypervisors, also known as bare-metal hypervisors, run directly on the host's hardware to control the hardware and manage guest operating systems. Examples include VMware ESXi, Microsoft Hyper-V, and Xen. These hypervisors are typically used in enterprise environments for server virtualization.

Type 2 hypervisors, also known as hosted hypervisors, run on top of an existing operating system. They rely on the host OS to manage hardware resources and provide a virtualization layer for guest operating systems. Examples include VMware Workstation, Oracle VirtualBox, and Parallels Desktop. These hypervisors are commonly used for desktop virtualization and testing purposes.

Hypervisors offer several benefits, including improved resource utilization, enhanced scalability, and simplified management of IT infrastructure. They enable organizations to consolidate multiple physical servers into a single virtualized environment, reducing hardware costs and energy consumption. Additionally, hypervisors facilitate the creation of isolated environments for development, testing, and disaster recovery purposes.

However, hypervisors also introduce some challenges, such as potential performance overhead and increased complexity in managing virtualized environments. Organizations must carefully evaluate their specific requirements and consider factors like compatibility, scalability, and management capabilities when selecting a hypervisor for their virtualization needs.
