Platform Engineering and Security

Modern software delivery faces growing complexities, from managing diverse cloud environments to ensuring security and compliance. Platform engineering has emerged as the solution, creating a secure, efficient path for developers. This book will help you understand this approach and build the tools necessary to streamline your software lifecycle.

This book walks you through the essential components of a platform. You will begin by learning the foundational concepts of platform engineering, understanding the culture and product mindset, and designing a robust architecture. It will show you how to codify infrastructure and security using policy as code, with a special focus on leveraging Kubernetes as the core of a secure delivery platform. You will also learn to embed security through the shift left approach and the creation of self-service capabilities. The book concludes with insights into observability, data lakes, and the future of the field with AI/ML and Pai-Ops.

By the end of this book, you will develop an understanding of platform engineering, along with the practical knowledge required to build, manage, and optimize a secure software delivery platform. You will be equipped with the practical knowledge to reduce developer cognitive load, accelerate product development, and ensure consistent security and governance, transforming your organization's approach to software delivery.
