Jan Giacomelli - 2 years ago

Running async tasks is challenging by itself. Require continuous zero-downtime deployment, and it gets even harder.
This talk presents battle-tested techniques and approaches to run your Celery workers on top of AWS ECS with Fargate while being able to deploy tens of times per day.

This talk presents techniques, approaches, and practical configuration examples that allow you to run your Celery workers on top of AWS ECS with Fargate. It starts by presenting the problems you encounter when dealing with async tasks. Next, we'll take a look at ECS and its configuration examples - which parameters to tweak to achieve the best result. After that, we'll check Celery configuration examples that comply with ECS requirements. We'll finish by overviewing techniques for implementing tasks in a way that supports ECS + Celery configuration while allowing continuous deployment all the time.
