What is Hypervisor in Cloud Computing and its types?

The hypervisor is a virtual machine monitor (VMM) that manages resources for virtual machines.

 The name hypervisor is suggested as it is a supervisory tool for the virtual machines.

There are mainly two types of hypervisors :

Type-1: the guest Vm runs directly over the host hardware, e.g Xen, Hyper-V, VmWare ESXi

Type-2: the guest Vm runs over hardware through a host OS, e.g Kvm, Oracle virtualbox

hi,,


In virtualization, the hypervisor (also called a virtual machine monitor) is the low-level program that allows multiple operating systems to run concurrently on a single host computer. Hypervisors use a thin layer of code in software or firmware to allocate resources in real-time. You can think of the hypervisor as the traffic cop that controls I/O and memory management.
There are two types of hypervisors: Type 1 and Type 2.

Type 1 hypervisors run directly on the system hardware. They are often referred to as a "native" or "bare metal" or "embedded" hypervisors in vendor literature.

Type 2 hypervisors run on a host operating system. When the virtualization movement first began to take off, Type 2 hypervisors were most popular. Administrators could buy the software and install it on a server they already had.

A hypervisor or virtual machine monitor (VMM) is a piece of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor is running one or more virtual machines is defined as a host machine. Each virtual machine is called a guest machine.

Type-1, native or bare-metal hypervisors
These hypervisors run directly on the host's hardware to control the hardware and to manage guest operating systems.
Type-2 or hosted hypervisors
These hypervisors run on a conventional operating system just as other computer programs do. Type-2 hypervisors abstract guest operating systems from the host operating system. VMware Workstation, VMware Player, VirtualBox and QEMU are examples of type-2 hypervisors.
