Hardware Virtualization

The abstraction of physical computing resources from the software that uses those resources.

What is Hardware Virtualization in cloud computing?

Hardware Virtualization, also known as server virtualization, is a process that allows for the creation of a virtual version of a physical server, known as a virtual machine. This is a fundamental technology that makes cloud computing possible, as it allows multiple virtual machines to run on a single physical machine, each with its own operating system and applications.

  • Hardware virtualization allows for better utilization of resources, as multiple virtual machines can share the resources of a single physical server.
  • It provides flexibility and scalability, as new virtual machines can be created quickly and easily, and resources can be allocated and reallocated as needed.

How does Hardware Virtualization work?

Hardware Virtualization works by using a software layer, known as a hypervisor, to emulate the underlying hardware. This allows multiple operating systems to run simultaneously on a single physical machine.

  • The hypervisor manages the physical resources and allocates them to each virtual machine as needed.
  • Each virtual machine operates as if it were a separate physical machine, unaware that it is sharing resources with other virtual machines.

Hardware Virtualization Example

A software development company needs to test its new application on different operating systems. Instead of investing in multiple physical servers, each running a different operating system, the company uses hardware virtualization. They create multiple virtual machines on a single server, each running a different operating system. This allows them to test their application on multiple platforms, while saving on hardware costs.
