I do agree that people tend to over-complicate their architectures initially, this is premature optimization of another form. That being said: * Microservices don't need to be written in the host language, nor do you need to deal with creating wrappers. Granted interacting with kafka/ampq isn't frictionless. * Microservices can be upgraded or scaled out individually without touching the larger application as a whole. * Microservice calls can be deferred and scheduled easily.
