Abstract : Nowadays, executions of composite Web services are typically conducted by heavyweight centralized engines. The cost of deploying a centralized engine is usually too high for a large number of small businesses or end-users and presents some weaknesses dealing with privacy issues. In addition, a centralized engine becomes a potential processing and communication bottleneck as well as a central point of failure. Therefore, problems and requirements, such as loose coupling, are pushing service infrastructures toward more decentralized and dynamic interaction schemes. In this paper, we propose a decentralized alternative system for the execution of composite Web services based on the chemical analogy. This chemical paradigm provides a high-level execution model that allows executing composite services in a fully decentralized manner. This system is composed by interconnected nodes communicating through a shared space containing both control and data flows, allowing to distribute part of the composition among nodes without the need for any centralized coordination.
