Supervisors are one of the most important features of Otp. They monitor other processes and take action if anything goes wrong, restarting the failed process or possibly escalating the problem to a higher level. Layering supervisors into supervision trees allows you to create highly fault-tolerant systems. (Logan, Merritt, and Carlsson 2010)
