Abstract: An apparatus includes a processor to: receive a request to perform a job flow defined in a job flow definition; retrieve the most recent versions of a set of task routines to perform a set of tasks of the job flow; analyze each interface of each task routine by which a data set is input or output during execution to identify dependencies where two task routines exchange a data set, and are written in different programming languages; execute the set of task routines to perform the job flow; in response to identifying such a dependency, convert the data set from a form supported by the programming language of one of the two task routines and into a form supported by the programming language of the other; store one of the forms within a federated area; and transmit a result report output during the performance to a remote device.

Abstract: An apparatus includes a processor to: receive a request for a federated area (FA) package including a FA storing a job flow definition; retrieve an instance log of a past performance that includes identifiers of the job flow definition, a data object employed as an input to a past performance, and a task routine executed in the past performance; employ an identifier to identify an FA storing a data object employed as an input; employ an identifier to identify an FA storing an executed task routine; generate the FA package to include the FAs storing the job flow definition, the instance log, the data object and the task routine, and include a copy of each in its respective federated area within the FA package; include an integrity value for each FA in the FA package; and transmit the FA package to the requesting device.

Abstract: An apparatus includes a processor to: grant a first device access to a first federated area, but not a second device; grant the second device access to a second federated area, but not the first device; grant the first and second devices access to a base federated area; maintain inheritance relationships among the federated areas so an object stored in the base federated area is as accessible to the first device as an object in the first federated area and is as accessible to the second device as an object in the second federated area; and maintain priority relationships among the federated areas so priority is given to providing the first device access to a task routine stored in the first federated area, and to providing the second device access to a task routine stored in the second federated area, over a task routine stored in the base federated area.

Abstract: An apparatus includes a processor to: receive a request from a first remote device to provide a second remote device with access to an existing federated area; allocate storage for a new private federated accessible to the second remote device and not to the first remote device; maintain an inheritance relationship between the existing and new private federated areas in which an object stored in the existing federated area is made accessible to the second remote device to the same extent as an object in the new private federated area; and maintain a priority relationship between the existing and new private federated areas as an exception to the inheritance relationship such that priority is given to providing the second remote device with access to a task routine stored in the new private federated area over a task routine stored in the existing federated area that performs the same task.

Abstract: An apparatus includes a processor and a storage storing instructions causing the processor to: maintain a federated area; receive a request to perform a job flow with a data set from a remote device; retrieve a job flow definition specifying the tasks of the job flow from the federated area; determine whether there is an instance log in the federated area generated by a previous performance of the job flow with the data set; in response to there being such an instance log, compare the version specified in the instance log of each task routine for each task to the most recent version stored in the federated area; and in response to each version specified in the instance log matching the most recent version, provide the remote device with access to a result report generated by the previous performance in lieu of generating a new result report.
