  1. BehindTheStack: The Evolution of Netflix's Architecture

    Stop copying design patterns without understanding the problems that created them.Netflix’s architecture wasn't drawn on a pristine whiteboard; it was forged by critical failures. In this book, we dive into the technical backstage of the world's largest streaming platform to understand the real trade-offs behind microservices, resilience, and global scale.Avoiding the hype and focusing purely on engineering, BehindTheStack dissects how the monolith was shattered, how data persistence evolved, and how a culture of freedom and responsibility shaped the code.Written for Architects, Tech Leads, and Senior Engineers who demand depth beyond shallow tutorials. Grab the Early Access version and follow the making of this scale survival manual.

  8. Secure All The Things!
    Secure All The Things!
    (with Spring Security)
    Josh Long

    UPDATE: Please don't pay for this!! It's free. Please just take it for free. I'd much rather give it away. Even when it's done, it'll still be free. I'm 100% NOT trying to make money on this. Tell your friends, and be sure to read it. Your applications lives and runs in more places - MCP, desktop applications, browser-based application, data integration pipelines, gRPC, browsers, etc. - than ever. Can your security framework keep up? If you're using Spring Security, then it definitely can, and this book - by Spring Developer Advocate Josh Long - will show you how.
