Important factors for estimating reliability of SOA

Service-Oriented Architecture (SOA) is basically a collection of individual services and these services interact with hence. Each interaction is loosely coupled and self-contained, so that each interaction is independent of any other interaction. Due to its complex nature, reliability estimation is a very tedious task. In any software system, reliability is one of the most important nonfunctional requirement and there are many factors that affect the systems reliability. In the previous work, there were many factors defined to estimate the reliability of a software system. In this paper, some new factors have been defined that affect SOA reliability.
