# **Proxmox Overview**

## **What is Proxmox?**

Proxmox Virtual Environment (Proxmox VE) is a powerful, open-source server virtualization platform designed for private and public cloud infrastructure. It combines two robust virtualization technologies within a single, intuitive interface:

- **KVM (Kernel-based Virtual Machine)** for full virtualization.
- **LXC (Linux Containers)** for lightweight containerization.

Proxmox VE is renowned for its user-friendly web-based management interface, versatile feature set, and seamless integration with diverse storage and networking configurations. Its adaptability makes it an excellent choice for home labs, small-to-medium businesses, and enterprise-scale environments.
