Ansible will faithfully deploy any security vulnerabilities you tell it to across your whole fleet, in just seconds! Don't make the mistake of thinking it's immune to errors.

Or, you can go as complex as possible and just hide them in mountains of garbage. "There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies."
