Häufige Fragen

Kurze Antworten für Besucher, die Graham-Miranda-Servicebereiche vergleichen.

What Linux distributions do you support?

Debian and Ubuntu LTS as the strongest area. Rocky/AlmaLinux supported. We are honest that we are not RHEL specialists at depth.

Can you administer servers we host elsewhere?

Yes — we can administer servers at Hetzner, OVH, AWS, on-premise, or anywhere with SSH access. No exclusivity required.

Do you do Ansible / config-as-code?

For long-lived servers yes — Ansible playbooks for repeatable configuration. For one-off servers, documented shell setup is acceptable.

What about Windows servers?

Linux is our specialty. We can advise on Windows server operations but recommend Windows specialists for primary Windows workloads.

Can you do kernel updates?

Yes, including planning reboot windows. Live kernel patching where the distribution supports it.

What about container hosts?

Docker and Docker Compose on a Linux host is a common pattern; we operate the host and the container runtime.
