Direct inter-process communication
reduces total system availability

A system communicating through an intermediary has finer availability
Participants are no longer obliged to wait
for the response from the counterparty

The AMQP protocol
AMQP (Advanced Message Queuing Protocol) is a messaging protocol that enables conforming client applications to communicate with
conforming messaging middleware brokers.

8. Exponential backoff using pure RMQ configuration (no Java code)

9. The configuration is still flexible and can be extended

RabbitMQ Delayed Message Plugin
Plugin is considered experimental, but it can solve
the problem of exponential backoff quite well.
However, there are few limitations:
• There is no replication of delayed messages
• Delay is not persisted
• There is a limit for the number of messages
