Sometimes, a web application server may stop due to an operating system restarting or crashing. Whenever a web server is killed, it is someone's job to bring it back to life. It is wonderful if that is automated. Supervisord is a tool that comes to the rescue. To make our API server run all of the time, we need to monitor it and recover it quickly. Supervisord is a generic tool that can monitor running processes (systems) and can restart them when they are terminated.
