A job is a core concept in FlowForce Server. It represents a task or a sequence of tasks to be executed by the server. Jobs can be as simple as one-step tasks such sending an email. However, you can also create jobs that perform multiple actions and pass the result (for example, a file) as parameter to another job. A job consists of input parameters, steps, triggers, and other settings.
A job instance is not the same as a job. When you configure a FlowForce job from the job configuration page, you create in fact a job configuration. Every time when the defined trigger criteria for a job apply, an instance of the job starts running. Job instances are distributed within the cluster as defined by the execution queue associated with the job. A job instance will always run in its entirety on a single cluster member.
