Managing trade-offs in adaptable software architectures

Making trade-offs in architecture is a fundamental activity in software design. As software is required to operate continuously in changing and uncertain environments, adaptability needs to be considered as a key issue, along with other more traditional software qualities. In this chapter, we introduce the concept of managing trade-offs in adaptable software architectures, discussing adaptability during the design of the software and as it runs. We outline important current approaches, challenges, and opportunities in managing these trade-offs.

Managing trade-offs in adaptable software architectures

Managing Trade-Offs in Adaptable Software Architectures explores the latest research on adapting large complex systems to changing requirements. To be able to adapt a system, engineers must evaluate different quality attributes, including trade-offs to balance functional and quality requirements to maintain a well-functioning system throughout the lifetime of the system. This comprehensive book brings together research focusing on how to manage trade-offs to help engineers architect adaptive systems in different business contexts, including state-of-the-art techniques, methodologies, tools, best practices, guidelines and guidance on future software engineering research and practice.Each contributed chapter considers the practical application of the topic through case studies, experiments, empirical validation, or systematic comparisons with other approaches already in practice. Topics of interest include, but are not limited to, how to architect a system for adaptability, software architecture for self-adaptive systems, understanding and balancing the trade-offs involved, architectural patterns for self-adaptive systems, how quality attributes are exhibited by the architecture of the system, how to connect the quality of a software architecture to system architecture or other system considerations, and more.
