Can I interest you in some Docker? If you're not using docker, and still have an extensive pile of Ansible scripts (you still need some, just not as much as before), it would really be worth your time to investigate how those scripts can be simplified using newer technology.
Ansible is useful for stuff like installing openssh on the server and setting up a secure sshd config file. Or setting up ufw.
You can do more, of course. I don't think Docker is suitable for that kind of stuff.
