Ubuntu Server LTS
Ubuntu LTS is the most common Linux on cloud instances and Kubernetes nodes, with five years of standard support and ten with Ubuntu Pro. It is our default for new Linux workloads unless a vendor says otherwise.
We build hardened Ubuntu images, keep unattended-upgrades sane, and handle release upgrades between LTS versions on a schedule.

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.
