I believe businesses like Microsoft, AWS, etc. all make their enterprise stuff super complicated as an excuse to sell support contracts. I remember trying to set up Windows Deployment Server, and the whole thing was very unreasonably complicated. I got it working, but I can see why businesses would pay for support contracts just so they have someone to call to walk them through all the esoteric steps, menus, options spread across the whole OS. The other side of it is, if you make your cloud offering super complex then you're pretty much locked into that platform because of sunk cost. Switching from Azure to AWS or whatever would be a huge undertaking.

That's really what frustrates me the most about modern technology. It's like tech and software developers love to rube-goldberg things, and everything is vastly more complicated than it needs to be. The thing is, tech people seem to like complexity for the sake of complexity. It gives them a fun [read: masochistic] puzzle to work on and makes them feel smart.

Heroku is great until you need to do something non-standard in your deployment, like compile node and configure a python virtualenv in the same deploy. Then you have to learn their Buildpack framework and that is a nightmare. It's a hugely complicated abstraction layer that, like one of the parent comments says, requires me to learn 200%. I have to learn all the steps to install/configure nodejs, then python, then how they decided to slap together a layer on top of it that made assumptions like you would only be doing one of these things.
