Where it is used

Microservice communication.

Common pitfall

Remote calls can fail, time out or run twice; design idempotent operations.

Where it fits in the course

Remote Procedure Calls is topic 8 of 51 in Distributed Systems & Cloud, rated Beginner. It follows Availability and Reliability. The next topic is Message Queues.
