Introducing CEP concepts to the Service Oriented Architecture (SOA) provides an opportunity to enhance the capabilities of SOA. A model that supports the CEP usage in SOA where the actual pattern recognition can be done by any external CEP Engine is proposed. We also define a new service type-a Complex Event Aware (CEA) service that automatically reacts to complex events specified in its interface.

We present the first empirical study that analyses Web Services Business Process Execution Language (WS-BPEL or BPEL) usage and characteristics of real world executable business processes. We have analysed 1,145 BPEL processes by measuring activity usage and process complexity. In addition, we investigated the occurrence of activity usage patterns. The empirical results provide fundamental knowledge on how BPEL specification and process design practices can be improved.

To enable reliable and robust service oriented information systems, it is important to establish an effective fault handling. WS-BPEL 2.0 specification does not provide sophisticated and reusable support for handling faults and challenges process designers with many obstacles in the process implementation. We introduce a novel policy driven fault handling framework for BPEL by extending the WS-BPEL 2.0 specification.
