# Introduction

This is assorted notes on what could go into the MakerFLOSS lab

---

# Requirements

- A space to experiment with new software
- A place where software could be "test run" for some time
- A place where errors are not causing IP loss
  - even if errors are real big !!

## More details

- Firewalled off from the production network
- Accessible from outside
- Potential for exposing services externally

---

## Constraints

- Cost conscious
- Support constant change

---

# Proposals

## Short term

A VPS in a (European) cloud with one public IP

---

## Midterm

Complement the VPS with some local hardware:

- Firewall with zones (VLANs, DNS/DHCP)
- Netbird access to services in Lab
- Switching infrastructure
- A primary "stable" Proxmox host
- A secondary experimentation machine
- A backup server
- Tunnel for external access via VPS public IP

---

### Basic Services in Lab

- Git: Forgejo
- ...

## Long term

replace VPS with a direct IP pinhole access

replace the "stable" FLOSS services running on VPS with modules runing on "stable" machine locally


# Design of Mid term solution
