Workers
Workers are responsible for running background jobs in your applications hosted on Her-
oku. This is a key feature for building really scalable web applications. Through the work-
ers, your applications can resize images, perform data upload to other servers, fetch API
data, send e-mail, and perform many other tasks in the background. Your web requests al-
ways return immediately improving the user experience. On Heroku, the workers are scal-
able, so you can increase or decrease the quantity at anytime.
