Services participating in the composition are usually coordinated according to a workflow, composed by several activities, each of which carried out by a service. The binding of services to workflow activities may be affected by several parameters (e.g., QoS, price, reputation, etc.). In this paper, we propose a service binding driven by a further important requirement, that is, the incompatibilities among services participating into the composition. To achieve a compatibility-driven composition we propose a solution where services assignment is configured directly by the engine coordinating the composite service. Moreover, the composition is generated such to implement a failure recovery strategy, that is, in case of some service failure the engine dynamically replaces the unavailable service.

Abstract

Services participating in the composition are usually coordinated according to a workflow, composed by several activities, each of which carried out by a service. The binding of services to workflow activities may be affected by several parameters (e.g., QoS, price, reputation, etc.). In this paper, we propose a service binding driven by a further important requirement, that is, the incompatibilities among services participating into the composition. To achieve a compatibility-driven composition we propose a solution where services assignment is configured directly by the engine coordinating the composite service. Moreover, the composition is generated such to implement a failure recovery strategy, that is, in case of some service failure the engine dynamically replaces the unavailable service.
