This video is inspired by my friend Heather Downing, who asked me how I would go about learning "something like... distributed PostgreSQL for instance". That's a great question!
I've set up distributed SQL Server before, but never had the need to do that with Postgres. The reason why is simple: I let DigitalOcean do it for me. Before that, it was Heroku or AWS.
That said, this really is something I should know how to do, so challenge accepted Heather!
