> The magic happens when an infrastructure team encapsulates their expertise, and then exposes that expertise as a service which can be used directly by developers.

I like this statement - how do you deal with educating team members on areas that require deep expertise? (e.g.., security, accessibility, localization).

Do you offer training, brown-bags, educational videos, or do you say "don't worry about it - if you do this in $x way, magic[1] will take care of you".

[1] Magic being defined as the compiler, automated tests, etc., feeding into a central feedback system (bugs, tickets, email, or whatever you use) telling you what you did wrong, and hopefully how to fix it.
