Proxmox

Proxmox is an open-source virtualization platform that allows users to manage virtual machines (VMs), containers, and storage resources. It provides a comprehensive environment for running and managing virtualized environments and is typically used for data center management, server consolidation, and IT infrastructure automation.

Proxmox primarily offers two key components:

1. Proxmox Virtual Environment (Proxmox VE): This is the primary product that provides both virtual machine management (based on KVM) and container-based virtualization (using LXC). Proxmox VE includes a web-based management interface, which makes it easy to manage virtual machines, containers, storage, and networks.

2. Proxmox Mail Gateway: This is a dedicated appliance for email security, filtering spam, and malware, which is often used in corporate environments.

Proxmox is known for being user-friendly, flexible, and cost-effective. It's often favored by small businesses, developers, and advanced IT users who want to set up and manage virtualized infrastructures with minimal cost, as it is open-source and offers enterprise features at no charge (with optional paid support).
