Homelab and Self-hosting

My work with Homelab and Self-hosting transcends technical enthusiasm; it is the laboratory where I develop expertise in systems administration and network architecture. Through self-hosting, I apply advanced Computer Science concepts to ensure data autonomy and high availability.

Hardware Architecture and Virtualization

The infrastructure is based on a robust virtualization environment:

• Main Node: Xeon 2680v4 with 64GB RAM and 2TB SSD.
• Secondary Node: Intel i5 Server, 32GB RAM, 3TB disk running Proxmox Backup Server (PBS).
• Backup Node: i3 with 2TB disk running Proxmox acting as standby hardware.
• Hypervisor: Operating with Proxmox VE for managing containers and virtual machines.
• Ecosystem: Sustains over 30 active services and applications.

Advanced Networks and Connectivity

The strategic differentiator of this laboratory is the deep implementation of network protocols:

• Dual-Stack with IPv6 Focus: Intensive use of native IPv6, integrated with my own ASN (AS209338).
• DNS Automation: Implementation of tools for automatic Reverse DNS (PTR) updates for all IPv6 devices.
• Retrocomputing Lab: Integration of legacy technology with 56k modems and a DSLAM concentrator, providing technical support to the TELESC and IRC.BENEDETTA projects.

Data Security and Resilience

Operational integrity is maintained by a rigorous 3-2-1 backup policy:

• Layer 1: Backup in PBS.
• Layer 2: Backup in external infrastructure (Remote PBS).
• Layer 3: Offline Backup.
