+- Microservices increase system complexity and we have separate services to serve different functions of the system. While this kind of architecture facilitates decoupling and segregation of duty, we need to handle the various communications among services. 
 
 It is better to think through the system's complexity before writing the code and carefully defining the boundaries of the services.

 We can mock requests and responses to validate the API design before writing code.
