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!

As explained in the first chapter, the main purpose of the EA function is to connect the IT department to different business lines and to make sure that IT investments and initiatives ultimately create business value. Most EA organizations are based on TOGAF.

Introducing TOGAF's ADM

The purpose of the Architecture Development Method (ADM) is to manage the development life cycle of the EA practice. The following screenshot shows the ADM proposed by TOGAF:

You can follow this to cover the entire spectrum of EA in a series of logical steps. However, because TOGAF is only a framework, you can perfectly decide to work only with some of the steps of that development cycle. The extent to which you apply TOGAF will be better understood once you have completed the preliminary steps and the architecture vision (Step A in Figure 2.2). If there were only one required step...
