What is Proxmox: A Complete Guide to Proxmox VE and Benefits

In today’s IT infrastructure, virtualisation is the cornerstone of all modern infrastructure. Australian businesses seek solutions that are not only cost-effective and scalable, but that are easy to manage and have great support. Proxmox Virtual Environment (Proxmox VE) is that platform. Combining a powerful open-source solution for managing virtual machines (VMs) and containers in a unified interface with comprehensive support agreements all for a business friendly rate.

An Introduction to Proxmox VE

• Proxmox VE is a complete open-source platform for enterprise virtualization. Proxmox allows users to manage virtual machines, Linux containers and software-defined storage in a single unified interface.
• Proxmox offers a cost effective platform to proprietary solutions, whilst providing advanced benefits such as flexibility, scalability and high availability (HA).
• Proxmox VE supports two virtualization technologies: Kernel-Based Virtual Machine (KVM hypervisor) for full virtualization and Linux Containers (LXC) for lightweight container virtualization.
• The platform is built on Debian Linux, providing a robust and stable foundation for hosting virtual machines and containers.

The Proxmox Virtual Environment Core Features

1. Web-Based Management Interface
   Proxmox provides a centralised, intuitive web interface for managing VMs, containers, storage and networking. As well as traditional CLI it also incorporates a REST API for automation.
2. High Availability (HA) Clustering
   Proxmox supports clustering, enabling multiple nodes to work together for redundancy and failover, to eliminate costly downtime.
3. Integrated Backup and Restore
   Proxmox comes complete with its own built-in backup tools, to allow for scheduled reliable backups, snapshots and disaster recovery planning. Further reducing the risk of data loss.
4. Software-Defined Storage
   Proxmox integrates with Ceph and ZFS thereby providing scalable and resilient storage options for all enterprise environments.
5. Software Defined Networking
   Proxmox’ s software-Defined Network (SDN) feature allows administrators to create virtual zones and virtual networks (VNets). These VNets provide a flexible and programmable way to manage networking across clusters. This is a necessity for multi-tenant environments, complex topologies and scenarios where network isolation, segregation and automation are required.
6. Open Source Software, Transparent and Secure
   The Proxmox environment is licensed under GNU AGPLv3. Proxmox guarantees transparency, security and a community-driven development.
