Designing Software Architectures: A Practical Approach
Description
Learn how to create successful architectural designs and improve your current design practices!
Designing Software Architectures, 2nd Edition, provides a practical, step-by-step methodology for architecture design that any professional software engineer can use, with structured methods supported by reusable chunks of design knowledge and rich case studies that demonstrate how to use the methods.
The Attribute-Driven Design method may not have changed since this book's first printing, but almost everything else about the industry has. In this newly updated edition, you will find new chapters on supporting business agility through API-centric design, deployability, cloud-based solutions, and technical debt in design.
Humberto Cervantes and Rick Kazman illuminate best practices for how architects should design complex systems so you can make design decisions in systematic, repeatable, and cost-effective ways. This book will help you become a better, more confident designer who can create high-quality architectures with ease.
The new edition includes:
- A clear explanation of the Attribute-Driven Design method
- New chapters focused on the technical environments and contexts of contemporary design
- Two new case studies on The Hotel Pricing System and Digital Twin Platform
- Coverage of current architecture topics like cloud computing, DevOps, and large-scale systems
- Methods to make architecture design agile and achievable
