How to implement Design Pattern for a microservices proxy?

0

Soon we will make our applications through Middlewares , I know that systems authentication will be through OAuth2 , but I have the following question:

Where should I begin to study related subjects and how could I adapt the applications we already have to a design pattern that works at this level of architecture. Could someone give me a simple example, how would I implement an email system for example?
