Abstract

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.

Dependent claims

A method, comprising:

obtaining a request to perform a workflow, the request including a definition of a task to be executed on a plurality of computing resources and a set of workflow parameters, the set of workflow parameters indicating a limitation on a number of active virtual computer system instances running the task on the plurality of computing resources and a failure criterion for the workflow;
initiating performance of the workflow by launching the task on a limited number of the plurality of computing resources such that a number of active virtual computer system instances running the task is in accordance with the limitation on the number of active virtual computer system instances;
determining that the failure criterion has been satisfied before the workflow is complete;
and
as a result of determining that the failure criterion is satisfied, stopping the workflow before the task is performed on all of the plurality of computing resources.

2 more elements

A system, comprising:

one or more processors;
and
memory storing computer-executable instructions that, if executed on the one or more processors, cause the system to:
obtain a request to perform a workflow, the request identifying a task to be executed on a plurality of resources and a set of workflow parameters that limit a number of active virtual computer system instances running the task;
initiate performance of the workflow by launching the task on the plurality of resources such that the number of active virtual computer system instances running the task is in accordance with the workflow parameters;
and
abort the workflow as a result of determining that a failure criterion has been satisfied before the workflow is complete.

4 more elements

A non-transitory computer-readable storage medium with executable instructions stored thereon that, as a result of being executed by one or more processors of a computer system, cause the computer system to at least:

obtain a request to perform a workflow, the request identifying a task to be executed on a plurality of resources and a set of workflow parameters that limit a number of active virtual computer system instances of the task;
initiate performance of the workflow by launching the task on the plurality of resources such that the number of active virtual computer system instances running the task is in accordance with the workflow parameters;
and
abort the workflow as a result of determining that a failure criterion has been satisfied before the workflow is complete.
