Cloud Networking and Resilience
Designing Scalable, Fault-Tolerant, and Highly-Available Cloud Network Architectures
By Cristian Critelli | Published by Apress Media, LLC (Springer Nature) | 2026
ISBN (Print): 979-8-8688-2435-7 | ISBN (eBook): 979-8-8688-2436-4
Introduction
Resilience is no longer a luxury — it is an imperative. In today’s cloud-native era, where digital services span time zones and serve users around the clock, the question is not whether failure will occur, but when. From widespread outages like the CrowdStrike global incident to subtle, hard-to-detect degradations in complex distributed systems, resilience has emerged as the defining characteristic of trustworthy, enduring cloud architectures.
Rather than centering purely on application-layer recovery or generalized high-level guidance, this book focuses on what is often the most underestimated yet critical layer: cloud networking. Networks are the lifelines of distributed systems. They connect services, users, regions, and environments. And they are often the first point of failure — and the last to be understood.
While many of the technical examples and reference architectures throughout this book are drawn from AWS, the principles and strategies presented are cloud-agnostic. Whether you work with Microsoft Azure, Google Cloud Platform, or another provider, the foundational patterns of resilient design remain consistent.

Who This Book Is For
Whether you are a cloud architect, network engineer, site reliability engineer (SRE), or DevOps practitioner, this book is a guide for building systems that are not only available, but truly resilient — systems that can absorb, adapt to, and recover from the unexpected with minimal disruption. The book assumes a foundational understanding of networking concepts such as IP addressing, routing, DNS, load balancing, and the OSI or TCP/IP models.
