Different models of dependable services in Service-Oriented Architecture

Abstract

Today, software architectures play an important role in developing large, complex and distributed systems. ServiceOriented Architecture (SOA) is a flexible, loosely coupled and dynamic architecture for developing different distributed systems. Since using this architecture is every day increasing in the design of software systems, creating dependable services in this architecture is one of the main challenges. In this paper, we review dependable services in the level of service-oriented architecture. There are various methods for creating dependable services. One of these methods is fault tolerance algorithms. This paper is a study on the methods for creating fault tolerance dependable services in service-oriented architecture.

Extended Fault Taxonomy of SOA-Based Systems

“…Forward recovery technique either ignores the fault service and goes forward to keep the rest of the system running with no harm or retries the faulty service again or substitutes the faulty service with the another service which would be sufficient to fulfill the task of the current faulty service. Four types of replication/repetition mechanisms [49] can be used for fault tolerance system: passive repetition, active repetition, N-version model, and return to back/check-point model. Brief explanations of local recovery strategies and global recovery strategies are as follows.…”

An implementation of cognitive management framework for the Internet of Things system

“…With the improvement of web service technology, SOA has a large development potential. Framework based on SOA is coarse-grained and looselycoupled with high flexibility in constantly changing environment [3]. In the past decades, a great deal of effort has been devoted to the study of proposing different frameworks in different scenarios and even instantiating in software platforms.…”

Measuring The Failure Rate In Service-oriented Architecture Using Fuzzy Logic

“…In [4], fault tolerance algorithm was introduced for creating reliability in service-oriented architecture. The idea of redundancy and integration were used in this study to prevent and keep faults constant.…”

“…These faults increase the rate of failure for the system [1]. Fault tolerance mechanism is one of the existing mechanisms for creating reliable services [4]. .…”

“…Today, service-oriented architecture is widely used as a flexible architecture for expanding dynamic systems [2,3].This system has feeble connections and dynamic configuration for expanding different distributing systems [4]. The services are self-descriptive in this architecture [2,5,6].…”
