### If you want Celery using detached mode (if you want to add more nodes, then you'll
### need to run with supervisor. That's not something I want to set up here right now
### since it's more advisable to just have a separate autoscaling group with a different
### script):
# celery -A config.celery_app multi start worker -B -l info

# The following is Django oriented where I'm starting my HTTP server. If you're using a
# different web framework, understand that my port is on 5000 so that NGINX, the reverse
# proxy, can handle all the requests.
# How many workers? https://docs.gunicorn.org/en/stable/design.html#how-many-workers

# Multiple servers, one deployment group for Celery and another for Django
# NOTE: If you can, make three groups: one specifically to run ONE instance of celery
# beat, another for all celery workers, and another for our web servers.
