Architecture-Based Software Reliability Estimation: Problem Space, Challenges and Strategies
نویسندگان
چکیده
In modern software-intensive systems, reliability is considered to be one of the most critical non-functional properties. To build software in a cost-efficient manner, reliability should be analyzed at architecture design time. In this paper, we consider the problem space of, challenges in, and strategies for architecture-based estimation of a software system’s reliability. Architecture-based reliability estimation is challenging –– during early design phases, architects lack information necessary for precisely determining a system’s reliability, such as the system’s operational profile and failure and recovery information. Thus, we explore how such information can be obtained from alternative sources. Finally, we present a critical overview of existing approaches to architecture-based reliability estimation, in order to indicate directions for future research.
