in this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. the engines are assumed to be implemented as composite web services. current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. the difficulty is to rollback the execution state of the workflo...

Service Oriented Architecture (SOA) is emerging to be the predominant architectural style of choice for many organizations due to the promised agility, flexibility and resilience benefits. However, there are currently few SOA metrics designed to evaluate complexity, effort estimates and health status of SOA solutions. This paper therefore proposes a SOA metrics framework which includes both ser...

Despite the wide range of advantages which many authors associate with the introduction of a service-oriented architecture (SOA), comprehensive SOA implementations continue to be scarce in practice. Consequently, questions arise as to how the concept is adapted in practice. This paper compares the scientific view of SOA concepts with initial practical experience from first SOA implementations. ...

به دنبال شیوع ویروس کرونا در جهان، بسیاری از تعاملات رسمی آموزشی سمت برگزاری بستر محیط مجازی سوق یافت و ادامة فرایند آموزش معماری نیز همانند همة دوره‌های آموزشی، دلیل تعطیلی دانشگاه‌ها، تنها برخط ممکن گشت. این میان کارگاه‌های طراحی معماری، منزلة کانون ویژگی‌های منحصربه‌فردی دارند که را سایر رشته‌های دانشگاهی جدا کرده است. نمونة بارزی یک مشارکتی، چندحسی، تجربه‌گرای مبتنی بر مسئله همین ویژگی‌ها م...

The concept of Service-oriented Architecture (SOA) is becoming increasingly important not only in research, but also in practice. SOA has emerged as a major topic, especially in regards to the banking industry as it is one of the cutting-edge industries concerning service-orientation. SOA implementation in the German banking industry varies, with some still in the adoption phase and others alre...
