Abstract
Decentralized orchestration offers performance improvements in terms of increased throughput and reducing response time. The idea of decentralized orchestration of BPEL is to partition the program into different partitions in such a way that each partition is executed by a different orchestrator; all sub-BPEL programs must be coordinated to achieve the overall program. On the other hand, decentralized orchestration brings temporal complexity level partitioning BPEL program to find a partition that maximizes the profile of service users and also the bottleneck at orchestration engine when running activities. The main objective of this paper is to provide decentralized execution environment which optimizes the execution of a business process described in BPEL. Our approach is based on two basic technologies namely: i) shared space that represents an environment of communication between intelligent agents, and ii) a set of cooperative agents to share execution.
