Answer

Celery consists of several key components:

  • Client/Producer: The application that creates and sends tasks
  • Message Broker: Middleware that routes tasks from producers to workers (e.g., RabbitMQ, Redis)
  • Worker: Process that executes the actual tasks
  • Result Backend: Optional storage for task results (e.g., Redis, Database)
  • Beat: Scheduler for periodic tasks
