A Model of Service-Oriented Computation
نویسندگان
چکیده
We propose a motivation from “first principles” of a small set of abstractions for ex-pressing and analyzing service based systems. In particular, we suggest the aspects ofdistribution, process delegation, communication and context sensitiveness, and loose cou-pling as specific to the service-oriented computational model. Distinguishing aspects ofour model are the adoption of a very simple, context sensitive, message-passing local com-munication mechanism, and a novel mechanism for handling exceptional behavior. Weinstantiate our model by extending of a fragment of the π-calculus, and show that behav-ioral equivalences, defined by strong bisimilarity and weak bisimilarity, are congruencesfor all operators.

متن کاملDevelopment of a framework to evaluate service-oriented architecture governance using COBIT approach
Nowadays organizations require an effective governance framework for their service-oriented architecture (SOA) in order to enable them to use a framework to evaluate their current state governance and determine the governance requirements, and then to offer a suitable model for their governance. Various frameworks have been developed to evaluate the SOA governance. In this paper, a brief introd...

متن کاملChanges in a Service Oriented Enterprise: A Game Theory Approach
Service Oriented Enterprises (SOEs) are subject to constant change and variation. In this paper, the changes are considered from an economic perspective based on service culture notion. Once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. We construct a game theoretic model trying to capture the possible conflicting i...

BPEL4WS: Workflows and Service Components BPEL4WS [1] provides the most complete realization to date of the workflow execution model in the context of a service oriented architecture. Service oriented architectures introduce a set of very distinctive abstractions that result in significant modifications of the basic workflow model as outlined in pre-existing workflow model, see [2] for example....
