Replace selected commercial applications with professional open-source alternatives where it makes technical and financial sense.
Examples include:
| Business function | Possible technology |
|---|---|
| Server operating system | Debian / Ubuntu |
| Identity management | FreeIPA |
| Single Sign-On | Keycloak |
| Office productivity | LibreOffice / Collabora |
| File collaboration | Nextcloud |
| VPN | WireGuard |
| Monitoring | Zabbix / Grafana |
| Firewall | OPNsense |
| Database | PostgreSQL / MariaDB |
| Web infrastructure | Nginx |
| Containers | Docker / Podman |
| Virtualization | Proxmox / OpenStack |
The objective is not to replace software simply because it is proprietary.
The objective is to determine where open technology can provide the same business capability with greater control and lower long-term dependency.
