scheduling as well. The execution units, called tasks, are executed concurrently on a single or more worker servers. Tasks can execute asynchronously (in the background) or synchronously (wait until ready) Overview This is a high level overview of the architecture. The broker pushes tasks to the worker servers. A worker server is a networked machine running celeryd. This can be one or more machines, depending available, see the configuration directive reference. #### 1.3.3 Running the celery worker server To test we will run the worker server in the foreground, so we can see what's going on in the terminal:

scheduling as well. The execution units, called tasks, are executed concurrently on one or more worker nodes using multiprocessing, Eventlet or gevent. Tasks can execute asynchronously (in the background) Overview This is a high level overview of the architecture. The broker delivers tasks to the worker nodes. A worker node is a networked machine running celeryd. This can be one or more machines depending on to different workers, or select different message topologies, by configuration or even at runtime. Worker nodes can be controlled from remote by using broadcast messaging. A range of built-in commands exist

work across threads or machines. A task queue’s input is a unit of work called a task. Dedicated worker processes constantly monitor task queues for new work to perform. Celery communicates via messages initiate a task the client adds a message to the queue, the broker then delivers that message to a worker. A Celery system can consist of multiple workers and brokers, giving way to high availability and second/minute/hour, or how long a task can be allowed to run, and this can be set as a default, for a specific worker or individually for each task type.
