Abstract: Methods, systems, and computer-readable media for a customer-facing service for service coordination are disclosed. Via a request gateway, a request to perform an operation is received. A data structure associated with the operation is retrieved. The data structure is generated based at least in part on one or more models and an indication of service operations. The one or more models are formatted using a modeling language associated with the request gateway. The data structure comprises a directed acyclic graph representing a flow of data between the service operations, and the flow of data is determined based at least in part on analysis of typed fields of the service operations. The request is processed to perform the operation based at least in part on the data structure, including invoking a plurality of the service operations using traversal of the directed acyclic graph.

Abstract: Methods, systems, and computer-readable media for request authorization using service coordination are disclosed. An authorization data structure and an operation data structure are selected based at least in part on a request for an operation. The authorization data structure comprises a directed acyclic graph representing a flow of data between service operations associated with authorization of the operation, and the operation data structure comprises a directed acyclic graph representing a flow of data between a service operations associated with execution of the operation. Authorization of the operation is attempted using the authorization data structure, comprising invoking one or more of the service operations associated with authorization. If the authorization is successful, then the execution of the operation is initiated using the operation data structure, comprising invoking one or more of the service operations associated with execution.

Abstract: An orchestration request indicating input data types and output data types of a collection of functions is received at a network-accessible service. At the service, one or more I/O operations that are to be performed at a data store to execute a dataflow corresponding to the request are inferred based on analysis of the input data types and output data types. A template representing the dataflow is stored, comprising respective nodes representing the functions and the I/O operations, as well as an indication of the sequencing of execution of the functions and I/O operations.
