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.

Configuring regional routing

Now that we have selected a regional topology and we know how to check the health of our regions, we can set up our regional routing. We will start by setting up a Content Delivery Network (CDN) for our micro frontend single page application (SPA). Then we will configure our BFF services with regional and global endpoints, and then we will add these to the CDN. Finally, we will setup a global endpoint for our event bus.

Content Delivery Network (CDN)

A Content Delivery Network (CDN) is a globally distributed network of edge locations design to deliver web content to users with low latency and high availability. A CDN, such as AWS CloudFront, is the perfect solution for delivering the static resources that make up a micro-frontend single-page application, like we covered in Chapter 3, Taming the Presentation Tier.During a regional disruption we need to ensure that we continue to respond to requests for the application's resource bundles. The CDN is our...
