Agile Software Architecture
1st Edition
Aligning Agile Processes and Software Architectures
Description
Agile software development approaches have had significant impact on industrial software development practices. Today, agile software development has penetrated to most IT companies across the globe, with an intention to increase quality, productivity, and profitability. Comprehensive knowledge is needed to understand the architectural challenges involved in adopting and using agile approaches and industrial practices to deal with the development of large, architecturally challenging systems in an agile way.
Agile Software Architecture focuses on gaps in the requirements of applying architecture-centric approaches and principles of agile software development and demystifies the agile architecture paradox. Readers will learn how agile and architectural cultures can co-exist and support each other according to the context. Moreover, this book will also provide useful leads for future research in architecture and agile to bridge such gaps by developing appropriate approaches that incorporate architecturally sound practices in agile methods.
Key Features
- Presents a consolidated view of the state-of-art and state-of-practice as well as the newest research findings
- Identifies gaps in the requirements of applying architecture-centric approaches and principles of agile software development and demystifies the agile architecture paradox
- Explains whether or not and how agile and architectural cultures can co-exist and support each other depending upon the context
- Provides useful leads for future research in both architecture and agile to bridge such gaps by developing appropriate approaches, which incorporate architecturally sound practices in agile methods
Readership
researchers, practitioners, and graduate students of software engineering and software architectures, people working in architecturally sensitive industries (e.g. safety critical systems) and industries migrating to agile
