Understanding Virtualisation: What Is It And How Does It Work?
Virtualisation is a technology that allows users to create and run virtual versions of computer hardware, operating systems, storage devices, and other resources. Instead of relying on physical hardware, virtualisation enables the use of a virtual environment that runs on top of a physical server.
In this virtual environment, multiple virtual machines (VMs) can be created, each with its own operating system and applications. Each VM operates independently of the others, allowing multiple operating systems and applications to run simultaneously on a single physical machine.
Virtualisation works by using a hypervisor, also known as a virtual machine monitor, to manage and allocate the physical resources of the host machine to the virtual machines. The hypervisor ensures that each VM has access to the necessary resources, such as CPU, memory, and storage, while also preventing conflicts between the VMs.
By enabling virtualisation, organizations can consolidate their infrastructure, reduce hardware costs, and improve resource utilization. It also provides flexibility and scalability, allowing for easy deployment and management of new virtual machines as needed.
Understanding how virtualisation works is crucial in determining whether to enable it and how it can benefit your organization.
