Uncovering the Mystery of What Hypervisor Is
Have you ever wondered which of the following component is called hypervisor? If so, you’ve come to the right place! This post will explain what a hypervisor is, the different types of hypervisors, and why they are so important.
What is a Hypervisor?
A hypervisor, also known as a virtual machine monitor, is a software program that manages the execution of multiple operating systems on a single host computer. In other words, it creates virtual machines that can run multiple operating systems concurrently. It is most commonly used in server virtualization, where multiple virtual machines can be created and managed on a single physical server.
The hypervisor is responsible for allocating the resources of the physical server among the virtual machines. It also ensures that the virtual machines do not interfere with each other’s operations. The hypervisor is responsible for providing the necessary hardware and software support for each virtual machine.
Types of Hypervisors
There are two main types of hypervisors: Type 1 and Type 2. Type 1 hypervisors, also known as bare-metal hypervisors, run directly on the physical hardware. They are the most efficient type of hypervisor, as they are not subject to the overhead of running on top of an operating system. Examples of Type 1 hypervisors include VMware ESXi, Microsoft Hyper-V, and Citrix XenServer.
Type 2 hypervisors, also known as hosted hypervisors, are installed on top of an existing operating system. They are less efficient than Type 1 hypervisors, as they are subject to the overhead of the underlying operating system. Examples of Type 2 hypervisors include VMware Workstation, Oracle VirtualBox, and Microsoft Virtual PC.
Why Hypervisors are Important
Hypervisors are important for a number of reasons. Firstly, they enable server consolidation by allowing multiple virtual machines to run on a single physical server. This reduces the amount of physical servers required, resulting in cost savings. Secondly, they enable rapid provisioning and deployment of virtual machines, making it easy to quickly provision new servers. Lastly, they enable easy migration of virtual machines between physical servers, allowing for easy scaling and load balancing.
Hypervisors are an essential component of server virtualization, and they are becoming increasingly important as organizations move to the cloud. By understanding what hypervisors are, how they work, and why they are important, you can make informed decisions about how to best use virtualization in your organization.
In conclusion, a hypervisor is a software program that manages the execution of multiple operating systems on a single host computer. There are two main types of hypervisors: Type 1 and Type 2. Hypervisors are important for server consolidation, rapid provisioning, and easy migration of virtual machines. Knowing which of the following component is called hypervisor is key to understanding how to best use virtualization in your organization.
