Author Jimmy Ray, a developer advocate on the Amazon Web Services Kubernetes team, provides a practical approach to integrating PaC solutions into your systems, with plenty of real-world examples and important hands-on guidance. DevOps and DevSecOps engineers, Kubernetes developers, and cloud engineers will understand how to choose and then implement the most appropriate solutions. Understand PaC theory, best practices, and use cases for security Learn how to choose and use the correct PaC solution for your needs Explore PaC tooling and deployment options for writing and managing PaC policies Apply PaC to DevOps, IaC, Kubernetes, and AuthN/AuthZ Examine how you can use PaC to implement security controls Verify that your PaC solution is providing the desired result Create auditable artifacts to satisfy internal and external regulatory requirements.
