Agreed on IAM, and TFAs comments that once you see the horrendous complexity in IAM you start seeing it everywhere else in AWS as well. And with IAM, after all the effort you've put in, you can never really tell what is and isn't enabled. If you run your own server you can check permissions, run access-control audit scripts, and so on, and say with a pretty good level of confidence that X is possible and Y isn't. With IAM it's more like "I'm pretty sure I figured out the right silly-walk for X, but I have no way to tell what else might be enabled".

AWS: I came, I saw, I threw up in my mouth a little, I left.
