Software Architecture for Busy Developers

By: Stéphane Eyskens

Overview of this book

Are you a seasoned developer who likes to add value to a project beyond just writing code? Have you realized that good development practices are not enough to make a project successful, and you now want to embrace the bigger picture in the IT landscape? If so, you're ready to become a software architect; someone who can deal with any IT stakeholder as well as add value to the numerous dimensions of software development. The sheer volume of content on software architecture can be overwhelming, however. Software Architecture for Busy Developers is here to help. Written by Stéphane Eyskens, author of The Azure Cloud Native Mapbook, this book guides you through your software architecture journey in a pragmatic way using real-world scenarios. By drawing on over 20 years of consulting experience, Stéphane will help you understand the role of a software architect, without the fluff or unnecessarily complex theory. You'll begin by understanding what non-functional requirements mean and how they concretely impact target architecture. The book then covers different frameworks used across the entire enterprise landscape with the help of use cases and examples. Finally, you'll discover ways in which the cloud is becoming a game changer in the world of software architecture. By the end of this book, you'll have gained a holistic understanding of the architectural landscape, as well as more specific software architecture skills. You'll also be ready to pursue your software architecture journey on your own - and in just one weekend!

Understanding design patterns and their purpose

A design pattern is an admitted best practice to tackle a common problem. Many applications face the same challenges, as follows:

  • They must be performant.
  • They must be testable.
  • They must be maintainable and should be able to grow over time.
  • They must be portable to some extent.
  • They must manage memory and the central processing unit (CPU) efficiently.
  • They must be able to scale.
  • They must support concurrency (thread safety).

The preceding list is only a subset of typical cross-cutting concerns. The purpose of a design pattern is to find the best approach to handle a common problem, regardless of whichever programming language is used.

Design patterns are inspirational and are not especially prescriptive about how the detailed implementation should be done. Design patterns remain high-level, and they aim to improve code quality as well as to ultimately adhere to the SOLID principles, a widely...
