Dumb communication pipes

 Microservices promote basic, time-tested, asynchronous communication mechanisms among microservices. As per this principle, the business logic should stay inside the endpoint and not be amalgamated with the communication channel. The communication channel should be dumb and just communicate in the communication protocol decided. HTTP is a favorable communication protocol, but a more reactive approach—queues is prevalent these days. Apache Kafka, and RabbitMQ are some of the prevalent dumb communication pipes providers.
