Virtualisierungsebene

Virtualisierungsebene refers to the conceptual layer within a computing system that abstracts physical hardware resources. This layer allows multiple operating systems or applications to run concurrently on a single physical machine, each believing it has exclusive access to its own dedicated hardware. The most common implementation of a virtualization layer is a hypervisor, also known as a virtual machine monitor (VMM).

Hypervisors can be type 1, running directly on the host's hardware, or type 2, running as an application on top of an existing operating system. The virtualization layer manages and allocates CPU, memory, storage, and network resources to the virtual machines (VMs). It intercepts requests from the VMs to the hardware and translates them, ensuring that each VM operates independently and securely from others.

This abstraction provides several benefits, including improved resource utilization, increased flexibility, faster deployment of new systems, and enhanced disaster recovery capabilities. It enables the creation of isolated environments for testing, development, and production, and is a fundamental technology behind cloud computing services. The performance and efficiency of the virtualization layer are critical factors in the overall performance of the virtualized environment.
