From the introduction, I can see a list of backend technologies. But do they have a high level architecture diagram? I don't know what I really need for production setup.
AFAICT needs a db (MySQL/Postgres) and a cache (Redis/Memcached) and one (or more?) web workers.
Then optionally also Celery workers (for "async queries" i.e. slow running)... not sure how optional that is though.
