Proxmox Virtual Environment is the complete open-source enterprise virtualization solution that integrates KVM hypervisors, LXC containers, storage and networking capabilities on a single platform.<\/p>\n

Having recently reached version 6, Proxmox Virtual Environment is growing a lot both in terms of quantity and quality of the features introduced with an eye always very attentive to ease of use and GDPR compliances.<\/p>\n

With the integrated web interface you can easily manage:<\/p>\n

VMs and containers
\nmanage storage and networking features
\nhigh availability clusters
\nbackup and restore,
\nlive migration
\nVM replica
\nfirewalls<\/p>\n

Proxmox Virtual Environment allows you to virtualize even the most demanding Linux and Windows application workloads.
\nBy combining two virtualization technologies, Proxmox Virtual Environment offers maximum flexibility to your virtual IT environment.<\/p>\n

By natively integrating support for high availability (HA) and thanks to the unique multi-master design, an additional management server is not required, saving resources and enabling high availability without a single point of failure (SPOF).<\/p>\n

Live \/ online migration of Proxmox Virtual Environment<\/h3>\n

With the built-in live\/online migration feature, you can move running virtual machines from one Proxmox Virtual Environment cluster node to another without any downtime or noticeable effects from the end-user side.<\/p>\n

Administrators can initiate this process via script or with the web interface, making it a simple process.<\/p>\n

It allows you to easily take a VM offline for maintenance or updates.<\/p>\n

Enterprise-ready<\/strong><\/h3>\n

Proxmox Virtual Environment represents a powerful yet easy-to-use solution capable of managing standalone nodes or hyper-converged cluster solutions.<\/p>\n

It supports different authentication sources and role-based user and permission management allowing full control of HA clusters.
\nREST APIs allow for easy integration with third-party management tools such as custom hosting environments.<\/p>\n

The open source development model guarantees interested users of the Proxmox Virtual Environment full access to the source code as well as maximum flexibility and security.<\/p>\n

The numbers of Proxmox Virtual Environment<\/strong><\/p>\n

The Proxmox Virtual Environment open source project has over 270,000 active hosts, the GUI interface is translated into 19 languages, and more than 40,000 members are active in the free community support forum.<\/p>\n
