Towards a Dynamic Replication Scheme for Processes with Open Services
Abul Ahsan Md. Mahmudul Haque, Weihai Yu · 2013
Business processes can benefit from the external knowledge widely available in the web in terms of open services. Traditional centralized approaches to services orchestration are subject to serious limitations for orchestrating processes with the wider range of open services. Dealing with these limitations calls for decentralized approaches. However, decentralized approaches are themselves faced with a number of challenges, including the possibility of loss of dynamic run-time states that are spread over the distributed environment. This paper presents a dynamic replication scheme for a decentralized orchestration approach, where a network of agents collectively orchestrate open services using continuation-passing messaging.
