Service Oriented Computing: Service Foundations

The foundations of Service-Oriented Computing are concerned with the precise definition of a service. This is not only about providing a verbal explanation of what a service is, what can be and what cannot be considered a service, but rather it is about identifying the appropriate service model. Defining what service properties, requirements, and behaviors are relevant and possible for any gene...

Service Oriented Computing

Service-oriented Architectures (SOA) facilitate the dynamic and seamless integration of services offered by different service providers which in addition can be located in different trust domains. Especially for business integration scenarios, Federated Identity Management emerged as a possibility to propagate identity information as security assertions across company borders in order to secure...

Trustworthy Service-Oriented Computing

In service-oriented computing environments, computing resources are managed as services, which can be used directly or composed into larger services. Service-oriented architecture has been widely adopted in modern distributed environments such as for cloud computing. However, the problem of finding desired services has arisen. Finding desired services can be divided into two sub-problems: servi...

Service-Level Agreements for Service-Oriented Computing

Service-oriented computing is dynamic. There may be many possible service instances available for binding, leading to uncertainty about where service requests will execute. We present a novel Markovian process calculus which allows the formal expression of uncertainty about binding as found in service-oriented computing. We show how to compute meaningful quantitative information about the quali...
