Engineering Resilient Systems on AWS

Preface

The need for resilient systems has reached unprecedented levels. This book explores the nuances of designing and implementing durable systems on Amazon Web Services (AWS). As technology becomes integral to enhancing customer experiences across industries, creating high-performing and resilient systems has become a top priority. Users now expect applications to be continuously available, raising the bar for system reliability.

Two key trends drive this book’s purpose: the increasing complexity of modern infrastructures and the growing importance of system reliability. As systems become more intricate, potential failure points multiply. Simultaneously, the costs associated with downtime or data loss have increased significantly. In this landscape, traditional approaches to system resilience fall short.

Many assume that cloud-based workloads are inherently resilient. While cloud infrastructure provides tools for building more robust systems, it doesn’t guarantee resilience. Effectively using the cloud demands a thorough understanding of both the platform and resilient architecture principles. This book aims to bridge this knowledge gap by examining best practices, architectural patterns, and a real-world example workload. It serves as a comprehensive guide for engineers, architects, and IT professionals.

Resilience encompasses more than just technology; it involves people and processes as well. While the book primarily focuses on hands-on technology, Part I reviews people ...
