"Designing a Robust Asynchronous Communication Process

Question

In a multi-node network, node A sends a message to node B, which then processes the message and sends a response back to A. Node A should continue its other tasks while waiting for the response. How would you design this asynchronous communication process, considering potential message loss, network congestion, and ensuring the order of messages?

Answer 1

Whenever I hear asynchronous tasks, first thing that comes to mind is Message Queues like Rabbit MQ, Kafka.

Now for handling,
Message loss, network congestion just setup a retry mechanism with retry limits until delivery acknowledgement is received.
