Exploring the World of Virtualization: Understanding Hypervisors, Containers, and Application Virtualization

In today’s rapidly evolving technological landscape, virtualization has emerged as a fundamental concept that underpins modern computing architectures. By abstracting physical hardware and creating isolated environments, virtualization enables greater flexibility, efficiency, and scalability in IT infrastructures.

Hypervisors: The Foundation of Virtualization

Hypervisors play a crucial role in virtualization by enabling the creation and management of virtual machines (VMs) on a single physical machine. There are two main types of hypervisors:

Type 1 Hypervisor (Bare Metal)

A Type 1 hypervisor, also known as a bare metal hypervisor, interacts directly with the underlying hardware of the host machine. It is installed directly on the physical hardware, without the need for an underlying operating system. Examples of Type 1 hypervisors include VMware ESXi and Microsoft Hyper-V.

Example: In a data center environment, a Type 1 hypervisor is used to partition a physical server into multiple VMs, each running its own operating system and applications.

Type 2 Hypervisor

In contrast, a Type 2 hypervisor, or hosted hypervisor, runs on top of a host operating system. It interacts with the underlying hardware through the host OS…
