Question

How do independent Microservices communicate with each other?

Answer 1

Microservices can communicate with each other through:

HTTP for traditional Request-Response.

Websockets for streaming.

Brokers or Server Programs running Advanced Routing Algorithms.

For message brokers, RabbitMQ, Nats, Kafka, etc., can be used, each built for a particular message semantic. Another way is to use Backend As A Service like Space Cloud, which automates the entire backend.
