I went to one too, and saw a talk about synchronising data between microservices and was astounded at how much work it was and the fact they had a whole team just to build tooling to debug issues on this specific company. Basically they store 100x more data than they need because of data duplication between microservices. The company didn't even have that much customers (<1000), data or even enough users (a handful per company), but duplication was still generating several terabytes. It's amazing how much complexity people are able to cram into simple system. (Interestingly enough there's another recent comment on another article here talking about this exact issue: https://news.ycombinator.com/item?id=32320660 https://news.ycombinator.com/item?id=32320660 )
