On the contrary. Using libraries with clearly defined interfaces makes it easier to combine those libraries into a single executable, reducing deployment and debugging complexity. It also dramatically improves performance given the lack of intermediate encoding/decoding protocol code and TCP/UDP hops. Experienced seasoned Architects knows this and work hard to remove unnecessary distributed complexity from systems they design. While “beginner experts” always pick the most complex “solution” for the job at hand. The worst spaghetti code I have ever seen in my 30+ year career is a 20+ years old Microservices architecture. So I can’t wait to read the future “We had a problem so we chose micro-services. Now we have N distributed problems + K impossible to debug obscure timing issues” articles.
