Debian
Debian is the base under Ubuntu and Proxmox and a fine server OS in its own right: minimal, stable and predictable. It suits infrastructure roles such as DNS, proxies, monitoring and mail relays.
We manage Debian with Ansible, unattended-upgrades for security patches and a tested path between major releases.

How we work
Linux fleets stay healthy through automation and discipline. We build servers from a standard image with Ansible, patch them on a schedule with a staging ring, keep SELinux or AppArmor on, and log everything to a central collector. The result is a fleet that looks the same everywhere and can be rebuilt from Git.
Migrations, whether CentOS to Rocky, RHEL 8 to 9 or Windows to Linux, are done per workload with a test pass, a cutover window and a rollback. We coordinate with application vendors and keep the paperwork for compliance.
Subscriptions and licences are reviewed as part of the work. Plenty of businesses pay for RHEL where Rocky would do, or run unsupported CentOS where a subscription would satisfy an auditor. We fix both directions.
