With StreamSets Data Collector, the scope of the REST API is limited to the Data Collector you are communicating with, so if you tell a Data Collector to start a pipeline, only that Data Collector instance will start the pipeline.

With StreamSets Control Hub, on the other hand, a job maps a pipeline to a Data Collector label and number of instances, so you can send a single 'Start Job' REST API call and Control Hub will run the job's pipeline on the relevant Data Collector instances.
