Rocky Linux and AlmaLinux
Rocky and Alma are the community rebuilds that replaced CentOS Linux when it was discontinued. They are binary compatible with RHEL, free, and exactly what most business servers need when no vendor demands a Red Hat subscription.
We migrate CentOS 7 and 8 systems with the official conversion scripts, standardize on one of the two, and manage patching with Ansible.

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.

Frequently asked questions
Rocky or Alma?
Both are fine. Pick one and standardize. We lean Rocky for closest RHEL parity and Alma when a client wants TuxCare extended support.
