The idea for this book originally came into existence during a time that the four authors were heavily involved in global deployments of large and complex networks focused on zero trust architectures. Pre-COVID, many of the authors were traveling up to 42 weeks a year, meeting with customers, supporting large deployments onsite, and hearing first-hand about the challenges, pitfalls, and gotchas they were experiencing from deploying advanced and new technology suites that could lead to a more robust and secure network architecture. Over time, the team observed the technology mature, the escalations and teething issues seen in the early days of deployments of zero trust networks subside, and customers shift gears to realize their visions of a more automated, dynamic, and secure estate, focusing on the principles of providing only the requisite access for a given service. In addition to the maturity of the technology, the expansion of domains to adopt zero trust principles moved beyond the campus, to other domains and verticals, such as edge compute, the data center, cloud, and deployment in containerized form factors in AI agents. These adoptions further cemented the need to ensure a robust and secure estate, regardless of the location of the user, endpoint, workload, or autonomous/semi-autonomous software process. The key focus areas of this book are not specific to a single technology; this title provides a focus on the domains of resilience, automation, security, and cloud architectures. While separate in their own right, when utilized together, they can result in a scalable, secure, and future-proof deployment. This book is aimed at security engineers, security analysts, site reliability engineers, network engineers, architects, and operations teams who have a key focus on optimizing their network deployments, increasing security, resilience, and automation within their organization. Given the experience of the authors, a heavy focus has been placed on real-life examples from their years of deployment experience globally. While it would have been easy to describe the solutions through rose-colored lenses, this book provides a candid overview of the good, the bad, and the ugly that you can experience on your journey toward building an automated, resilient, and secure enterprise estate.
