Orchestration and choreography language provide basic composition techniques and specification among services, but they don't give any secure manners or secure operation styles and specifications. For giving a general guide to implement secure orchestration and choreography, we give a formal approach for carrying out this goal. To this target, we address those by designing an extension of the Spi...
Web services are gaining acceptance as a standards-based approach for integrating loosely coupled services. Achieving high levels of reliability and availability of service-oriented application server in spite of service or infrastructure failures poses new challenges. According to the characteristic of performance parameters of service-oriented application sever, a new software aging forecasting...
