<!-- SC_OFF -->Every time I’ve seen microservices pitched, it sounds great on paper. Independent teams, clean ownership, scale only what you need.

Maybe I’ve just seen bad implementations, but I’m starting to think way fewer companies actually need microservices than we pretend. <!-- SC_ON --> submitted by /u/Mustela__ (https://www.reddit.com/user/Mustela__)
