To the software wide of the equation --> open source is NOT the answer, abstractions ARE. The problem with programmers TODAY is that they take technical article written by a a cloud provider as gospel, and start slathering large layers of priority api calls/technical debt all over their solution - because thats what example code is designed todo, LOCK YOU IN. No need for contract nasties when your devs are doing the work for them! Use an eggshell architecture, put your dependencies on the edge. global dependencies are the enermy. For IAC, thats a slightly different story.
