RailsConf 2021: High availability by offloading work - Kerstin Puschke

Unpredictable traffic spikes, slow requests to a third party, and time-consuming tasks like image processing shouldn’t degrade the user facing availability of an application.

I’ll explain their foundations and how they compare to each other, helping you to choose the right tool for the job.
