Different models of dependable services in Service-Oriented Architecture

Today, software architectures play an important role in developing large, complex and distributed systems. Service-Oriented 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.
