Foreword

I have known John for a little over two years through his involvement in cloud technologies, especially in serverless architectures and building applications using the Serverless Framework. He took us on a cloud-native journey, thinking and reasoning about new paradigms in building software on the cloud in his previous book, Cloud Native Development Patterns and Best Practices.

Continuing on his journey to explore cloud-native systems, he brings us his new book, JavaScript Cloud Native Development Cookbook, to showcase recipes in a cookbook format that deliver lean and autonomous cloud-native services. In a nutshell, the recipes in the book demonstrate how to build cloud-native software at a global scale, utilize event-driven architectures, and build an autonomous development environment, starting with a developer committing code to deploying the application using a continuous deployment pipeline.

Serverless computing is the way to go when building cloud-native applications. With no servers to manage or patch, pay-per-execution billing, no paying for idling, auto-scaling, and a microservices/event-driven architecture, there is really no reason not to adopt serverless computing.

In this book, John presents practical Node.js recipes for building serverless cloud-native applications on AWS. The recipes are battle-tested and work around the pitfalls that present themselves in real-life scenarios. The recipes are built with best practices and practical development workflows in mind.

John takes the traditional cloud-native principles and shows you how to implement them with serverless technologies to give you the ultimate edge in building and deploying modern cloud-native applications.

The book covers building a stack from scratch and deploying it to AWS using the Serverless Framework, which automates a lot of the mundane work, letting you focus on building the business functionality. It goes on to incorporate event sourcing, CQRS patterns, and data lakes, and shows you how to implement autonomous cloud-native services. The recipes cover leveraging CDN to execute code on the edge of the cloud and implementing security best practices. It walks you through techniques that optimize for performance and observability while designing applications for managing failures. It showcases deployment at scale, using multiple regions to tackle latency-based routing, regional failovers, and regional database replication.

You will find extensive explanations on core concepts, code snippets with how-it-works details, and a full source code repository of these recipes, for easy use in your own projects.

This book has a special place on my bookshelf, and I hope you will enjoy it as much as I did.
