1 What is RABBITMQ?RABBITMQ is one of the messaging middleware implementations of the AMQP (Advanced Message Queuing Protocol) that originated in the financial system and is used to store and forward messages in distributed systems, with good performance in terms of ease of use, scalability, and high availability.
