And, you add latency issues and overhead. With a function call you pass two int and get a string of length 120 (how much memory is this? little, very little), with microservices you make an api call using http with it headers and get a json, and maybe you could need 2 api calls. For me it's easy, just create a monolith, when you become facebook or netflix, split symfony services into microservices (just an example). Oh, and don't forget the developers who translate a specific function into an endpoint, you need a change in the caller and you must change the api!
