OpenVZ

OpenVZ is a technology that allows a single physical server to be divided into multiple isolated virtual environments called containers or virtual private servers (VPS). Each container acts like a separate server with its own resources, such as CPU, memory, and disk space, but they all share the same underlying operating system. This setup enables efficient, cost-effective hosting, as multiple virtual servers can run independently on one physical machine without the need for full hardware duplication. OpenVZ is popular for hosting websites, applications, and services due to its lightweight nature and resource efficiency.
