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 Chapter 10, Optimizing Observability, we covered work and resource metrics and learned how they provide autonomous teams with the information they need to fail forward fast.Throughout this book we have focused on creating bulkheads within our systems to control the blast radius when things go wrong. Our autonomous services have inbound and outbound bulkheads to protect them from upstream and downstream services and we use the natural bulkheads of cloud accounts to protect autonomous subsystems from each other.Now we turn our attention to multi-regional deployment. We will use cloud regions as another bulkhead to protect our systems from cloud provider disruptions. We will learn how to failover fast from an unhealthy region to a healthy region, so that our systems continue to run without downtime.In this chapter, we're going to cover the following main topics:

  • Justifying multi-regional deployment
  • Preparing for regional...
