A homelab is a self-hosted infrastructure and virtualization environment that is designed, deployed, and maintained locally. It consists of three physical servers, two routers, a network switch, and a Raspberry Pi 5, with Proxmox serving as the primary virtualization platform. It hosts multiple LXC containers and virtual machines, used to deploy, manage, and experiment with various services and technologies. Furthermore, it includes services exposed to the Internet, providing hands-on experience with system administration, networking, virtualization, deployments, monitoring, and infrastructure management in a real-world environment.
