Orchestration And Choregraphy
Web services can be used for implementing business processes and collaborations within and across organizations.
Two languages for web service composition available are-
1. Business Process Execution Language (WS-BPEL)
2. Choreography Description Language (WS-CDL)
Orchestration refers to composing web services for business processes. It is used for defining composite services and internal processes. It describes the private process model i.e. describes a specific business process that a web service executes. The orchestration approach assumes a single, central point of control over the entire scope of process execution.
Choreography refers to composing web services for business collaborations. It is used for defining how multiple parties collaborate in peer-to-peer manner as part of some larger business transaction. It describes the public process model i.e. describes the interaction in terms of the public (visible) message exchanges that occur between the web services. The choreography approach assumes execution control is shared, potentially across multiple business process engines or various technologies.
There are two reasons for separating the public and private aspects of the business process.
1. The internal processes and data can be hidden from the clients invoking the web services.
2. The implementation details of the the internal process can be changed without affecting the public business protocol.
