What is OpenVZ?
OpenVZ is an open source container-based virtualization platform for Linux operating systems. It provides operating system-level virtualization that allows multiple isolated virtual containers, called Virtual Private Servers (VPSs), to run on a single physical server.
With OpenVZ, each VPS runs its own operating system and applications separate from the other VPSs on the server. This is achieved through container isolation where each container gets allocated CPU time, memory, storage and other resources that are separate from other containers.
Some key features of OpenVZ include:
- Efficient server utilization - Multiple containers share the same Linux kernel allowing high server densities.
- Performance and isolation - Each container gets isolated CPU, memory, storage and networking resources for good performance.
- Live migration - Containers can be live migrated between physical servers with no downtime.
- Open source - OpenVZ is released under GPL and free to use.
Overall, OpenVZ is a lightweight, high performance virtualization solution well-suited for hosting services like VPS hosting, container clouds, and virtual data centers.
VirtualBox, QEMU, VMware Workstation Pro, Docker, Windows Sandbox, VMware Workstation Player, KVM (Kernel-based Virtual Machine), OpenStack, VMware Fusion, Distrobox, LXC Linux Containers, CoreCluster, containerd, SmartOS, Kata Containers are some alternatives to OpenVZ.
