Monika, you are the North Star I guide my ship with and I love you with all my heart. I couldn't have done this without your support and guidance.

To Deya, Will, Thor, and Tron, without whom my days would be as muted and monotone as this page.

David Justice

John Doak is the principal manager of Layer 1 Reliability Engineering at Microsoft. John led the development of the Azure Data Explorer and Microsoft Authentication Library Go SDKs. Previously, he was a Staff Site Reliability Engineer at Google. As part of network engineering, he created many of their first network automation systems. John led the migration of that group from Python to Go, developing Go training classes that have been taught around the world. He was a pivotal figure in transforming the network team to a network/systems group that integrated with SRE. Prior to that, he worked for Lucasfilm in video games and film. You can find his musings on Go/SRE topics and his Go classes on the web.

I'd like to thank Raleigh Mann who was my manager at both Lucasfilm and Google during most of my time there. His advice and steadfastness when standing beside me are why I still call him Boss today. Stephen Stuart, who gave me my initial foray into management, which I'm not sure I should thank or curse him for. Thanks to Less Lincoln, the man, the myth, the legend. Ive worked with Less for four years, hes as much a mystery box as when I first met him (and I think he likes it that way). Of course, I would never have gotten here without the love and support of my parents, I love you both. Thanks to Sarah Murphy, who was an early contributor to the book. And thanks to David Justice. Without his hard work and enthusiasm, I would not have been able to do this.

David Justice is the principal software engineer lead for the Azure K8s infrastructure and Steel Thread teams, which maintain a variety of CNCF and Bytecode Alliance projects. He is a maintainer of the Cluster API Provider Azure and a contributor to the Cluster API. Prior to that, David was the technical assistant to the Azure CTO, where he was responsible for Azure cross-group technical strategy and architecture. Early on at Microsoft, he was a program manager leading Azure SDKs and CLIs, where he transitioned all Azure services to describe them using OpenAPI specifications in GitHub and established automations to generate Azure reference docs, SDKs, and CLIs. Prior to working at Microsoft, David was the CTO of a mobile CI/CD SaaS called CISimple.

Thank you to my lovely, supportive wife, Deya, for encouraging me to pursue time-consuming activities such as writing a book, educational pursuits, start-ups, and her favorite, golf. Deya and Will, you will never know how much your love, hugs, and support powered me through late nights and droughts of creativity. This book would not be possible without the brilliance, reliability, and counter-perspectives of my coauthor, John, for whom the word example means a 30k-line robust application. Thank you to the whole Packt team and all the reviewers, but especially Romy Dias who edited my work into something more closely resembling English prose. Finally, thank you Dad and Papa for always believing in me.

Trieu Pham is a software engineer with various technical ideas. His current focus and specialty are on API development, microservices, DevOps, and Golang. He has a bachelor's degree in mathematics and computer science, a master's degree in computer engineering, and a PhD in engineering.

Lukasz Sudol is a senior director of engineering at GumGum. He began working in the e-commerce industry by developing backend systems. During the past decade, his work has focused on developing high-availability application architectures for AdTech. He enjoys helping people to develop and working with interesting technologies.

I would like to thank my family, my fiancee Marcelina, and my friends who understand the time and commitment it takes to research and test engineering tools that are constantly changing. And to the reader, I hope my contribution will help you get through the book more easily.
