Abstract: One of the key problems of building complex service-oriented distributed applications is reliability of the processing despite possible failures of interacting entities. Some attempts to solve this problem have been proposed, including interaction compensation, service replication or rollback-recovery, among others. Yet, only the last one promises to develop mechanisms allowing automatic restoration of a consistent processing state, fully masking the failure occurrence. Unfortunately, the notion of consistent state is ambiguous and has not been formalised in the context of the service-oriented architecture (SOA). In this paper we propose formal definitions of contract guarantees and demonstrate that they can be successfully used to flexibly define consistency models for recoverable SOA applications.

Keywords: service-oriented architecture; recoverable SOA; reliability; fault tolerance; distributed processing; rollback recovery; consistency; contract guarantees; processing reliability; automatic restoration; failure occurrence.
