What is Hyper-V?
Hyper-V is a virtualization platform developed by Microsoft, which allows users to create and manage virtual machines (VMs) on a physical host machine. It is a native hypervisor, meaning it runs directly on the host machine’s hardware, providing a high level of performance and reliability. Hyper-V is widely used in data centers and cloud environments to provide a scalable and flexible infrastructure for deploying and managing virtualized workloads.
Main Features of Hyper-V
Hyper-V offers a range of features that make it a popular choice for virtualization, including:
- Hardware Virtualization: Hyper-V uses hardware-assisted virtualization to provide a high level of performance and reliability.
- Live Migration: Hyper-V allows for live migration of VMs between hosts, making it easier to manage and maintain virtualized workloads.
- High Availability: Hyper-V provides high availability features, such as clustering and replication, to ensure that virtualized workloads are always available.
