1. Resource efficiency: OpenVZ utilizes a single Linux kernel and all guest instances (containers) share the host kernel. This makes it more resource-efficient as it doesn’t have to run multiple full-fledged virtual machines and can have hundreds of containers on a single server.
1. High Performance: OpenVZ creates multiple secure, isolated Linux containers on a single physical server enabling better server utilization. It also allows for maximum performance for your applications as it runs directly on the server hardware.
1. Ease of use: OpenVZ is simple to use. Containers can be easily created, started, stopped, restarted, backed up, restored, and migrated between hosts.
1. Scalability: With OpenVZ, you can create as many VPS instances as your server’s resources will allow, up to thousands of them.
1. Fast Booting: Since a container shares the host kernel, booting is almost instantaneous.
1. Live Migration: OpenVZ allows for the live migration of a container from one host to another without any downtime, which is ideal for load balancing and maintenance.
1. Less Overhead: Since it uses a single Linux kernel to power multiple VPSs, it requires less overhead resources.
1. Strong Isolation: Although all containers share the same underlying kernel, OpenVZ provides good isolation between containers.
1. It is free: OpenVZ is free and open source, reducing the costs associated with licensing fees.
