WebJob downloads a program or script from a remote WebJob server and executes it in one unified operation. Any output produced by the program/script is packaged up and sent to a remote, possibly different, WebJob server. WebJob is useful because it provides a mechanism for running known good programs on damaged or potentially compromised systems. This makes it ideal for remote diagnostics, incident response, and evidence collection. WebJob also provides a framework that is conducive to centralized management. Therefore, it can support and help automate a large number of common administrative tasks and host-based monitoring scenarios such as periodic system checks, file updates, integrity monitoring, patch/package management, and so on.
