Ansible will be terrible slow to update things if you're geographically far from the servers. Updating around 100 servers from another continent already takes longer than a 5 minute TTL. Parallel connections only work up to a point before a playbook run always have at least one failure and requires a re-run.

Ansible also does not have locks or parallel users coordination, so you’ll need a single user/VM/GHA workflow running the playbook or at some point concurrent users will start overriding each other.
