Proxmox

Recently I started to work with Proxmox 6.3, and I fell in love with it!

Proxmox VE is an open-source hypervisor free to use base on GNU General Public License, but support is paid. It is very easy to deploy and use. Can be installed on old pcs as well as High-End servers.

It is based on Debian system. The backend services are not new, but powerful and reliable services well known to all Linux users and admins. It supports LXC containers as well as QEMU/KVM virtual machines. Featuring that using of containers is similar to vm’s on GUI, and make containers very easy-to-use and handy.

It also supports CEPH and RBD to build a distributed object store and file system designed to provide excellent performance, reliability and scalability.

Documentation for Proxmox is very well-made, simple and complete and community support is also available for free.

Clustering is simple and easy use; you can cluster non-hardware-similar hosts as cluster members.

Proxmox VE is a complete virtualization management solution for servers. In production and with lots of machines, you need hypervisors, management suits and backup solutions. But in proxmox all is provided as ONE package. Simple instances or scheduled backups are provided in few clicks. Management also is a user-friendly and simple to use web-based package.
