 The Job Service facilitates the scheduled execution of tasks in a cloud environment. These tasks are implemented by independent services, and can be started by using any of the Job Service supported interaction modes, based on Http calls or Knative Events delivery.

 For example, every time the workflow execution reaches a state with a configured timeout, a corresponding job is created in the Job Service, and when the timeout is met, a http callback is executed to notify the workflow.
