Hyper-V: Microsoft's Virtualization Platform Hyper-V is a hardware virtualization tool from Microsoft that allows users to create and manage virtual machines (VMs) on a single system. It helps optimize resource use, run legacy software, test applications across multiple platforms, and improve IT efficiency with features like isolated environments for enhanced security. Available on Windows and Windows Server, Hyper-V supports Windows, Linux, and FreeBSD as guest operating systems. It offers key benefits like better resource management and security, but has limitations with hardware-dependent or latency-sensitive applications. Overall, Hyper-V is a powerful solution for efficient, scalable virtualization.
