Top 5 OpenVZ alternatives

Last updated: September 20, 2014
OpenVZ
OpenVZ is container-based virtualization for Linux. OpenVZ creates multiple secure, isolated Linux containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.
The best OpenVZ alternatives:


Docker


Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. Consisting of Docker Engine, a portable, lightweight runtime and packaging tool, and Docker Hub, a cloud service for sharing applications and automating workflows, Docker enables apps to be quickly assembled from components and eliminates the friction between development, QA, and production environments. As a result, IT can ship faster and run the same app, unchanged, on laptops, data center VMs, and any cloud.

KVM


KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream.

Citrix XenServer


Citrix XenServer is an industry and value leading open-source virtualization platform for managing cloud, server and desktop virtual infrastructures. Organizations of any size can download XenServer for free to virtualize demanding workloads and automate management processes – increasing IT flexibility and agility and lowering costs.

VMware vSphere


Build your own cloud infrastructure in your datacenter and remote sites on VMware vSphere the world’s leading server virtualization platform. Virtualize your x86 server resources and aggregate them into logical pools for allocation of multiple workloads. Get network services optimized for the virtual environment, along with simplified administration and management. Reduce the complexity of back-end storage systems and enable the most efficient storage utilization in cloud infrastructures.

Parallels Virtuozzo


Parallels Virtuozzo Containers is an operating system virtualization solution that maximizes your investment in server hardware. Parallels Virtuozzo Containers is uniquely suited to Cloud server virtualization, enabling near instant provisioning and on-the-fly modification of hosting and Cloud server plans while delivering maximum density, cost efficiency and application performance.
