OpenVZ offers a great solution for clients that do not need kernel access on their VPS and can benefit from the burst-able RAM limit that is much faster.

OpenVZ is an Operating System-level server virtualization solution that’s built on the Linux platform. To begin with, it creates isolated and secure virtual private servers (VPS) or virtual environments on a single physical server. As a result, this enables better server utilization and ensures that an application’s resource usage is optimized.

Furthermore, each virtual environment functions as a stand-alone server. For example, these virtual environments can be rebooted independently and have their own root access, users, IP addresses, memory, processes, files, applications, system libraries, and configuration files.

In addition, OpenVZ offers the security of a dedicated server because a container cannot be accessed by other containers running on the hardware node. Therefore, it provides both efficiency and strong isolation, making it a reliable choice for server virtualization.
