And they often are! Because that's mainly one of the advantages... You can simply outsource a spec of the endpoints and that's it => flop over a ourservice.swag

And they often are! Because that's mainly one of the advantages... You can simply outsource a spec of the endpoints and that's it => flop over a ourservice.swagger.yml and get a working system back. Possibly in a language/framework you team has no experience with, but it was cheap. Recent fun; a bunch of microservices written by the same contractor were killing the shared db (the 'state' of all microservices); so while most were running fine, some were hitting the db hard and costing the company quite a lot of money until it was fixed. No-one felt it was their responsibility to test & fix because it was an external company and they 'delivered' according to spec. There are many ways to do this better, but it happens quite a lot (also with monoliths ofcourse but there I find it faster/easier to diagnose + fix (depending on the size; I guess there is a point somewhere in LoC where microservices start to shine).
