Adaptable Coordinated Service Compositions (WP-JRA-2.2)

by Branimir Wetzstein last modified Apr 24, 2012 10:38


The resulting models for QoS-aware and adaptable services and service compositions are an additional advancement beyond existing approaches, comprising results in adaptation triggers and approaches, monitoring, analysis, and prediction of QoS characteristics, SLA and KPI violations:

  • S-Cube defined adaptation triggers for service composition in SBAs. The approaches for identifying adaptation needs were closely related to monitoring of service compositions and their non-functional and QoS characteristics.
  • S-Cube developed adaptation approaches for service compositions such as the use of fragments, aspect-orientation, service infrastructure adaptation, on-line testing and evolution of the business process.
  • The network proposed fragmentation as an approach for improving reusability of service compositions and choreographies, and for supporting adaptation of compositions and models for context-aware service compositions (enabled by a framework for context-aware process evolution) and models for service compositions based on human-provided services and social media approaches.
  • S-Cube developed frameworks for multilevel and distributed service adaptation focusing on event logs analysis to support service execution and adaptation and to allow predicting violations of SLAs and created a decision support for service adaptation by monitoring run-time service discovery, preventing runtime SLA violations.
