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!

SOA promotes reusability across the entire enterprise landscape by exposing business capabilities in the form of services. SOA emerged in the last decade of the previous century, with the aim of decoupling applications. Before SOA, it was very common to have client applications directly connect to each other, or to a shared database with read/write permissions. This led to big issues and to the formation of an enterprise-level monolith, as described in the previous section, to the extent that changing anything could pose problems to many applications, leading to a lack of agility and an ever-increasing amount of time required to make small changes.

The following diagram shows a typical SOA implementation:
