Abstract

Scalability, consistency and reliability are among the key requirements for orchestration of BPEL processes. We present a fully decentralized approach to orchestration of BPEL processes that is of continuation-passing style, where continuations, or the reminder of the executions, are passed along with asynchronous messages for process orchestration. Furthermore, we identify and address some consistency issues that are more challenging for decentralized orchestrations.
