Towards context-aware adaptive fault tolerance in SOA applications
Jonas Buys, Vincenzo De Florio, Chris L. Blondia · 2011
Software components are expected to exhibit highly dependable characteristics in mission-critical applications, particularly in the areas of reliability and timeliness. Redundancy-based fault-tolerant strategies have long been used as a means to avoid a disruption in the service provided by the system in spite of the occurrence of failures in the underlying components. Adopting these fault-tolerance strategies in highly dynamic distributed computing systems, in which components often suffer from long response times or temporary unavailability, does not necessarily result in the anticipated improvement in dependability.
