Virtualization

Virtualization is a technology that allows multiple operating systems or applications to run on the same computer or server as separate, isolated entities, as if they were on separate physical machines. It enables you to run multiple virtual computers on one physical computer, each with its own operating system and resources, improving utilization, security and scalability.

VMware ESXi

VMware ESXi is a bare-metal hypervisor, a layer of software that runs directly on a physical server to virtualize its hardware resources. It creates virtual machines (VMs) which are software-based, isolated duplicates of a physical computer that can run its own operating system and applications. By using ESXi, multiple VMs can run on the same physical server, sharing its resources, but remaining isolated from each other. This allows for better utilization of hardware resources and makes it easier to manage, deploy and maintain multiple VMs.

Microsoft Hyper-V

Microsoft Hyper-V is a hypervisor technology built into Windows that allows users to create and manage virtual machines (VMs). It runs on the host operating system and creates isolated, virtual environments for VMs to run on. Each virtual machine can run its own operating system and applications, and it appears to the virtual machine as if it has its own dedicated hardware resources, even though it is actually sharing the physical resources of the host. With Hyper-V, you can run multiple virtual machines on a single physical server, making it easier to manage, deploy and maintain multiple VMs. This can also result in better utilization of hardware resources and improved flexibility.

KVM

KVM (Kernel-based Virtual Machine) is a virtualization technology for Linux operating systems. It allows multiple virtual machines (VMs) to run on a single physical host machine, sharing the same hardware resources such as CPU, memory, and storage. Each VM operates as a separate, isolated environment, with its own operating system and applications. This makes it possible to run multiple, different operating systems on one server, making more efficient use of hardware resources and allowing for easy consolidation of multiple servers into one.
