Jobs (e.g. uptime checks, payment processing, sending emails) are added to the job queue (Redis) and background workers pick it up from there, and churn through them asynchronously. Most of the work happens in the background, so in my case, Redis is a critical piece of infrastructure.

Ah, of course! I saw background jobs and Redis but didn't make the connection at the time.
