For multiple tasks, RabbitMQ can command the Celery worker to work on these tasks one at a time. The RabbitMQ broker is good for huge messages and it saves these messages to disk memory.

To start, we need to set up a new Celery instance that will utilize the RabbitMQ message broker using its guest account. We will use the AMQP protocol as the mechanism for a producer/consumer type of messaging setup. Here is the snippet that will replace the previous...
