In my experience I would add: Building systems out of "lego blocks".
It is possible to get all the pieces that are needed to build a data server for a enterprise pre built form cloud providers. Then plumb them together so the mostly work.
When the heat comes on and peopel are using it for real and it must scale (even a little) it blows up horribly.
The "leggo bricks" save a lot of time and money, and mean that people with only half a clue can build large impressive looking systems, but in the end people like ,e are picking up the pieced
