I’m a strong proponent of microservices but only for one thing - the ability to scale the number of engineers working on a product. If you can abstract out a contract between each service then developers are unburdened to iterate as fast as they can without constant communication overheads.

The idea of a 2 dev org deciding to replace simple maintenance free function calls with authenticated, TLS-secured, retry-able, service-located, rate-limited remote procedure calls (in the general sense of the term) and replacing simple method parameters with serialisation and deserialisation overhead… it’s all just pretty absurd.
