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.

Addressing event-first concerns

Our event-first approach to building autonomous services is a bit of a paradigm shift. And as with any paradigm shift, there is plenty of opportunity for misunderstandings in the early adoption phases. This is completely understandable because we often have to unlearn the practices that we followed before. This can result in a resistance to change and the formulation of arguments against the change that turn out to be myths or anti-patterns.As architects, we need to make the effort to understand the source of these concerns, so that we can set the record straight and lead the product in the right direction. To this end, I am including the most common misconceptions that I have encountered. Let's start with a common misunderstanding of event lakes.

System of record versus source of truth

The event lake is a key element of our architecture. It provides a complete audit trail of all the actions and changes that occur within a subsystem. So, it seems...
