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!

Hands-on with a serverless architecture example

I introduced serverless architectures in Chapter 6, Impact of the Cloud on the Software Architecture Practice, so it is time to go through a small example to let you taste the serverless flavor. Remember that true serverless is based on fully delegating the infrastructure to the cloud provider, and costs are consumption-based. Therefore, it is hard to be cloud-agnostic, so I had to choose a cloud vendor for this example. Due to this, I went for Azure. The following diagram shows our very simple application:

We are going to reuse the same K8s cluster to host the event publisher, which publishes events to a custom event grid topic. An Azure function, represented by the event handler in the preceding diagram, subscribed to our topic and gets triggered by the event grid whenever a new event is being pushed. As I explained earlier, serverless architectures...
