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.

Securing the perimeter

Security-in-depth is a layered approach where each additional layer provides more measures that an intruder must penetrate before gaining access to the valuable data within a system. In Chapter 6, A Best Friend for the Frontend, we covered the BFF pattern and in Chapter 7, Bridging Intersystem Gaps, we covered the ESG pattern. These services represent the boundary of the system because they support external actors. Before requests reach these services, we want them to pass through a hardened perimeter that helps weed on illegitimate requests before they can have a negative impact on the system. Fortunately, for our serverless systems, this is an area where the cloud provider's global resources provide an amazing level of scalability and protection. Let's look at how we can leverage global/edge infrastructure, federated identity providers and encrypt data in transit.You can find a template for global resources used across a subsystem here: https://github...
