Microservices replaces monolithic systems with distributed systems. Almost by definition, this means an explosion of moving parts. In a demo context, when everything is running on a single laptop, it’s easy to forget that a microservices architecture really is a system with lots of different things trying to communicate with one another over an unreliable network. Even in a ‘real’ system, with virtualization and containers, it’s not always obvious how much complexity is involved in the aggregated system — as long as things work well. After all, the reason the fallacies of distributed computing are known as fallacies is because they’re assumptions we all tend to make.
