Distributed applications require coordination of distributed software components in order to achieve a common goal. A coordination model that abstracts the complexity of network communication eases the development of such applications. The objective is to design collaboration with remote hosts in the same way as local interactions. Separation of coordination logic and application code increases maintainability, as components can be easily replaced with alternative versions. Different applications often have similar requirements on their coordination logic, e.g. concerning replication or load balancing. Instead of developing this functionality for each application separately, reusable generic patterns should be applied and adapted to the corresponding use case. In this paper, we describe how a coordination model based on asynchronous, data-driven communication among autonomous peers can be enhanced …
