[Animation Explanation] Virtualization Overview

Virtualization refers to the creation of a virtual version of something, such as an operating system, a server, or a network resource. There are two main types of virtualization: Type 1 and Type 2.

Type 1 virtualization, also known as bare-metal virtualization, runs directly on the host’s hardware without the need for an underlying operating system. It allows multiple operating systems to run concurrently on a single physical machine, each in its own isolated environment. Type 1 hypervisors provide a layer of abstraction between the hardware and the virtual machines, allowing for better performance and security. Examples of Type 1 hypervisors include VMware ESXi, Microsoft Hyper-V, and Citrix XenServer.

Type 2 virtualization, also known as hosted virtualization, runs on top of an existing operating system. It allows users to run multiple virtual machines on a single physical machine by creating a virtual environment within the host operating system. Type 2 hypervisors are easier to install and manage, but they typically suffer from slower performance due to the additional layer of abstraction. Examples of Type 2 hypervisors include Oracle VirtualBox, VMware Workstation, and Parallels Desktop for Mac.

In summary, Type 1 virtualization provides better performance and security by running directly on the hardware, while Type 2 virtualization is easier to install and manage but suffers from slower performance due to running on top of an existing operating system. The choice between Type 1 and Type 2 virtualization depends on the specific requirements of the use case
