Virtuaalmasinapõhisest

Virtuaalmasinapõhisest refers to a computing paradigm where multiple virtual machines (VMs) run on a single physical machine. Each virtual machine is an independent operating system environment that behaves as if it were a separate computer. This is achieved through virtualization software, often called a hypervisor, which manages the allocation of physical resources like CPU, memory, and storage to each VM.

This approach offers several advantages. It allows for efficient utilization of hardware by running multiple isolated systems concurrently. It also simplifies server consolidation, reducing the need for numerous physical servers and their associated power and cooling costs. Furthermore, VMs provide excellent isolation, meaning that if one VM crashes or encounters a security issue, it typically does not affect other VMs on the same host. This isolation is also beneficial for testing software in different operating system environments or for running legacy applications that may not be compatible with modern hardware.

The creation and management of virtual machines are facilitated by various virtualization platforms. These platforms enable users to create, start, stop, and clone VMs with ease. Snapshots of VM states can be taken, allowing for quick rollback to a previous configuration if needed. Disaster recovery is also enhanced, as entire VMs can be backed up and restored. Virtuaalmasinapõhisest is a foundational technology for cloud computing, enabling the on-demand provisioning of computing resources.
