In the real world [of software], things are solved by choosing the tech with the lowest barrier to entry, not reading any documentation, getting a minimum-not-quite-viable-proof-of-concept working in a development environment, then making that production, over-working a select few to keep it running, and a lot of crossed fingers and heads in sand. The only thing you'll learn from different verticals and sizes is how size and scope have no correlation to how things are built or whether they work well.

The interesting part is how larger scale makes things fail more often, and the response to increased failure can either be running around with your hair on fire for years, or a solid firefighting team, or actually teaching teams not to build products that catch on fire. The only way to get the last one is by focusing on people, not technology.
