    摘要: A workflow orchestration service coordinates the performance of a workflow. The workflow is accomplished by performing a task on each resource in a set of resources. In an embodiment, the resources are virtual computer system instances and the task is a set of commands to be run on each of the virtual computer system instances. As a result of a request, the workflow orchestration service initiates a task instance for each resource in the set of resources in accordance with a set of workflow parameters. In an embodiment, the workflow parameters include a parameter that limits the number of concurrent active task instances. In an embodiment, the workflow parameters identify condition that aborts the performance of the workflow. In an embodiment, upon failure of a task instance, the workflow orchestration service rolls back the state of an associated resource to a state before the task was initiated.
