EXPANDABLE SERVICE ARCHITECTURE WITH CONFIGURABLE ORCHESTRATOR

摘要

Methods, systems, and computer programs are presented for adding new features to a network service. A method includes an operation for receiving, by an orchestrator, a sequence specification for a user activity that identifies a type of interaction between a user and the network service, which includes the orchestrator and service servers. The sequence specification includes a sequence of interactions between the orchestrator and a set of service servers to implement the user activity. Further, the method includes operations for configuring the orchestrator to execute the sequence specification when the user activity is detected, for processing user input to detect an intent of the user, and for determining that the intent corresponds to the user activity. The orchestrator executes the sequence specification by invoking the set of service servers, and by causing presentation to the user of a result responsive to the intent of the user.
