What is OpenVZ?
OpenVZ is a container-based virtualization solution for Linux, allowing multiple isolated Linux systems to run on a single physical server. It is a popular choice for web hosting providers, cloud computing, and other applications requiring efficient resource utilization. OpenVZ provides a lightweight and flexible way to deploy and manage virtual environments, making it an attractive option for those seeking a cost-effective and scalable solution.
Main Features
Some of the key features of OpenVZ include:
- Container-based virtualization: OpenVZ uses containers to isolate and manage virtual environments, providing better performance and resource utilization compared to traditional hypervisor-based virtualization.
- Lightweight: OpenVZ has a small footprint, requiring minimal resources to run, making it suitable for resource-constrained environments.
- Flexible: OpenVZ supports a wide range of Linux distributions and can be easily integrated with existing infrastructure.
