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.

Governing without impeding

As architects, once we have defined the architectural boundaries of the system, we need to let go and get out of the way, unless we want to become the impediment to innovation. But letting go is difficult. It goes against our nature; we like to be hands-on. And it flies in the face of traditional governance techniques. But we must let go for the sake of the business, whether it realizes this or not.Governance has an understandable reputation for getting in the way of progress and innovation. Although it has good intentions, the traditional manual approach to governance actually increases risk, instead of reducing it, because it increases lead time, which diminishes an organization's ability to react to challenges in a modern dynamic environment. But it doesn't have to be this way.We have already taken major strides to mitigate the risks of continuous innovation. We define architectural boundaries that limit the scope of any given change, and we fortify...
