Non-functional properties evaluation in Service Oriented Architecture (SOA) is still mostly an open challenge. Although this is a problem that has been already partially explored with some success, there is lack of consolidated results for more complex SOA applications based on services composition. This paper presents a contribution to performance evaluation of SOA-based applications integrated by BPEL. The evaluation technique is based on a performance-oriented reinterpretation of the BPEL specification as a performance modeling language within a multiformalism framework. The approach is based on automatic translation of PerfBPEL into Markov chains and it is implemented by means of SIMTHESys modeling and analysis framework to enable the interaction with other performance oriented formalisms.

Abstract
Non-functional properties evaluation in Service Oriented Architecture (SOA) is still mostly an open challenge. Although this is a problem that has been already partially explored with some success, there is lack of consolidated results for more complex SOA applications based on services composition. This paper presents a contribution to performance evaluation of SOA-based applications integrated by BPEL. The evaluation technique is based on a performance-oriented reinterpretation of the BPEL specification as a performance modeling language within a multiformalism framework. The approach is based on automatic translation of PerfBPEL into Markov chains and it is implemented by means of SIMTHESys modeling and analysis framework to enable the interaction with other performance oriented formalisms.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
