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 this chapter, you learned why it is important to create services that focus on user activities and how this helps teams accelerate the pace of innovation. You learned about the BFF pattern and how to combine the event sourcing and CQRS patterns to create user-facing services. And you learned how to apply the BFF pattern throughout the different phases of the data life cycle. You also learned how to implement a function-level nano architecture and how to choose between REST and GraphQL.In the next chapter, we will cover the External Service Gateway (ESG) pattern and see how it creates an anti-corruption layer that frees teams to focus on the functionality of their system. We will look at variations of the ESG pattern and cover integration with third-party systems, legacy systems, other autonomous subsystems, and more.
