Have you looked at RedHat's Ansible Automation Platform (a.k.a Ansible Tower)? it's a GUI for Ansible that might be useful. Ansible Automation Platform
Another might be RedHat's Cockpit, you get a gui per server, but then can also be centrally managed via the sidebar Cockpit
Both support Ubuntu/Debian even though it's RedHat... (something feels icky recommending them after the whole centOS/Rocky S..t show)
I don't run enough servers to warrant setting this all up at the moment, but I am slowly getting there. Likewise I didn't want the overhead of Cockpit per server, for small VPS's. I was thinking of making something myself, but that's just as much complexity and security headaches to deal with.
I am interested if anyone else has other recommendations too.
