It allows you to schedule virtually any job (e.g. such as calling HTTP/S endpoints). You can automate everything, including retries in case of failure, run jobs right away, on a recurring schedule, or at some point in the future. The scheduler allows you to manage all of your automation tasks in a single place via simple UI or command line.
