Providing configurable workflow capabilities

摘要

Techniques are described for providing clients with access to functionality for creating, configuring and executing defined workflows that manipulate source data in defined manners, such as under the control of a configurable workflow service that is available to multiple remote clients over one or more public networks. A defined workflow for a client may, for example, include multiple interconnected workflow components that are specified by the client and that each are configured to perform one or more types of data manipulation operations on a specified type of input data. The configurable workflow service may further execute the defined workflow at one or more times and in one or more manners, such as in some situations by provisioning multiple computing nodes provided by the configurable workflow service to each implement at least one of the workflow components for the defined workflow.

1. A computer-implemented method comprising:
receiving, by one or more configured computing systems of a configurable workflow service, configuration information from a client of the configurable workflow service for a defined workflow, the configuration information specifying multiple workflow components of the defined workflow and interconnections between at least some of the multiple workflow components; provisioning, by the one or more configured computing systems of the configurable workflow service, multiple computing nodes to each implement at least one of the multiple workflow components, at least one of the multiple computing nodes being provided by the configurable workflow service; and implementing the defined workflow for the client by initiating, by the one or more configured computing systems of the configurable workflow service, performance of defined activities on the multiple computing nodes that correspond to the implemented workflow components, the defined activities including:
one or more first activities involving obtaining input data from one or more data sources external to the configurable workflow service;one or more second activities involving producing intermediate results data by performing data manipulation operations that are based at least in part on the obtained input data; andone or more third activities involving producing output data based at least in part on the intermediate results data of the second activities.
