The Broker (RabbitMQ) is responsible for the creation of task queues, dispatching tasks to task queues according to some routing rules, and then delivering tasks from task queues to workers.
The Consumer is the one or multiple Celery workers executing the tasks. You could start many workers depending on your use case.
The Result Backend is used for storing the results of your tasks. However, it is not a required element, so if you do not include it in your settings, you cannot access the results of your tasks.
