Is S.O. a good example of a complicated/large distributed system? I couldn't find any quick googleable results on how many people work on their site. The reason I ask is I'm working on a product with 30-ish different pods/teams (maybe about 200 - 250 engineers) working on their respective modules, microservices, etc. From my understanding with talking to a lot of others at conferences, is that our distributed system is fairly small (in terms of functional modules/teams, transactions, etc..). Anyway, even at our small-ish scale, I couldn't imaging running our platform as a single app that were were able to scale up with better hardware. Also, I think how a company supports multi-tenanting would play a big role in deciding how this works, too, because you can have scenario with a monolith and DB but you have it partitioned by individual tenant dbs, app servers, etc, and you still have a huge pile of hardware (real or virtual) you're dancing around in....
