A Redundancy Protocol for Service-Oriented Architectures
نویسنده
چکیده
Achieving high-availability in service-oriented systems is a challenge due to the distributed nature of the architecture. Redundancy, using replicated services, is a common software strategy for improving the availability of services. However, traditional replication strategies are not appropriate for service-oriented systems, where diverse services may be grouped together to provide redundancy. In this paper we describe the requirements for a redundancy protocol and propose a set of processes to manage redundant service providers.

متن کاملAn Enhanced Service Oriented architecture for building Web-based applications
Service Oriented Architectures have recently emerged as a promising approach to develop Web-Based service provision environments. These architectures are characterized by federating services into a single, dynamic distributed system which is capable of spontaneously discovering and configuring itself upon service connections and disconnections. This work proposes a new architectural model, name...

Architectural principles such as loose coupling are the key drivers behind the adoption of service-oriented architectures. Service-oriented architectures promote concepts such as composition, process modeling, protocol design, declarative programming, event-based programming, and object-document mapping. These architectural ideals can be fraught with challenges for developers who are faced with...

متن کاملFairness as a QoS Measure for Web Services
Service Oriented Architectures (SOAs) are component-based architectures, characterized by reusability, modularization and composition, usually offered by HTTP (web services) and often equipped with a Quality of Services (QoS) measure. In order to guarantee the fairness property to each client requesting a service, we propose a fair version of the (Soft) Concurrent Constraint language to deal wi...
