The guest operating system runs on a separate level above the hypervisor. Native hypervisors are software systems that run directly on the host's hardware to control the hardware and to monitor the Guest Operating Systems. Let us now discuss both of these in detail. It creates a virtual platform on the host computer, on top of which multiple guest operating systems are executed and monitored. It is also called as the Virtual Machine Monitor (VMM). A schematic illustration is given below − Understanding Different Types of HypervisorsĪ hypervisor is a thin software layer that intercepts operating system calls to the hardware. This allocation is done through network connection.

This is widely used in datacenters where you have a big storage and it helps you to create, delete, allocated storage to different hardware. The following illustration shows the VMware schema − Storage Virtualization It helps you in creating multiple switching, Vlans, NAT-ing, etc. It is a part of virtualization infrastructure, which is used especially if you are going to visualize your servers. For example – Docker can be used for that purpose. The virtualization technology isolates applications from the underlying operating system and from other applications, in order to increase compatibility and manageability. We change their desktops with thin clients and by utilizing the datacenter resources.

This is similar to server virtualization, but this time is on the user’s site where you virtualize their desktops. It is virtualizing your server infrastructure where you do not have to use any more physical servers for different purposes. Let us now discuss each of these in detail.

Services and Applications Virtualization.

Today the term virtualization is widely applied to a number of concepts, some of which are described below −

The creation of one virtual resource from one or more physical resource.

The creation of many virtual resources from one physical resource.

It can also include making multiple physical resources (such as storage devices or servers) appear as a single virtual resource.” This includes making a single physical resource (such as a server, an operating system, an application or a storage device) appear to function as multiple virtual resources. Virtualization hides the physical characteristics of computing resources from their users, their applications or end users. In Wikipedia, you can find the definition as – “In computing, virtualization is a broad term that refers to the abstraction of computer resources.

They are completely separated and independent from each other. Virtualization is a technology that helps us to install different Operating Systems on a hardware.
