title: How to implement Rest APIs in monolithic architecture
body: <p>I understand (somewhat) what are differences between monolithic , microservices .
  And also what is SOA it is a service consumer/provider architecture and microservice is subset of SOA. and they use Restfull/SOAP APIs to communicate.
  So when a a request something he/she does using Rest/SOAP API but how in a Monolithic architecture a client request through which API? I searched all the links/blogs on google, videos on youtube but still I am not clear about this.</p>
  
  <p>Or may be my whole understanding is not correct.</p>
