Software Architecture Patterns for Serverless Systems - Second Edition

By: John Gilbert

Overview of this book

Organizations undergoing digital transformation rely on IT professionals to design systems to keep up with the rate of change while maintaining stability. With this edition, enriched with more real-world examples, you’ll be perfectly equipped to architect the future for unparalleled innovation. This book guides through the architectural patterns that power enterprise-grade software systems while exploring key architectural elements (such as events-driven microservices, and micro frontends) and learning how to implement anti-fragile systems. First, you'll divide up a system and define boundaries so that your teams can work autonomously and accelerate innovation. You'll cover the low-level event and data patterns that support the entire architecture while getting up and running with the different autonomous service design patterns. This edition is tailored with several new topics on security, observability, and multi-regional deployment. It focuses on best practices for security, reliability, testability, observability, and performance. You'll be exploring the methodologies of continuous experimentation, deployment, and delivery before delving into some final thoughts on how to start making progress. By the end of this book, you'll be able to architect your own event-driven, serverless systems that are ready to adapt and change.

In this chapter, we learned how to define architectural boundaries that enable change. The key is understanding that people (that is, actors) are the source of change and then aligning our boundaries along these axes of change. We found that event-first thinking, with its focus on verbs and facts, naturally helps us with this alignment.We brought this all together to divide a system into autonomous subsystems, and these into autonomous services. We saw how we can create arbitrarily complex systems following this simple fractal pattern of autonomous components. Then, we dissected the anatomy of autonomous services and learned how to leverage observability and automation to govern without impeding innovation.In the next chapter, we will start digging into the details of our architecture. We will learn how the micro frontend approach, along with other new techniques, helps to bring the seemingly endless churn at the presentation layer under control.
