Playing with SOA, EDA and Event processing in the Cloud - Christophe Hamerling, Linagora. Abstract : The PLAY project ( is developing an elastic and reliable architecture for dynamic and complex, event-driven interaction in large highly distributed and heterogeneous service systems. Such an architecture will enable ubiquitous exchange of information between heterogeneous services, providing the possibilities to adapt and personalize their execution, resulting in the so-called situational-driven process adaptivity.
