You can assign resources to Command task instances in the Worklet or Workflow Designer. You might want to assign resources to a Command task if you assign the workflow to an Integration Service associated with a grid. When you assign a resource to a Command task and the Integration Service is configured to check resources, the Load Balancer dispatches the task to a node that has the resource available. A task fails if the Load Balancer cannot find a node where the required resource is available.
