"OpenStack Keystone: Architecture and Implementation Guide"
"OpenStack Keystone: Architecture and Implementation Guide" is the definitive reference for architects, operators, and developers who seek a deep understanding of Keystone—the identity, authentication, and access management service underpinning OpenStack clouds. Beginning with Keystone's fundamental concepts, the guide meticulously unpacks projects, domains, users, and roles, before contextualizing Keystone's pivotal integration with other OpenStack components and enterprise identity providers. Readers are introduced to both native and federated protocols, advanced authentication models, and the API interactions essential to multi-tenant, hybrid, and large-scale deployments.
Delving into Keystone's internal architecture, the book provides a comprehensive technical roadmap: from modular service design and plugin development to fine-grained policy enforcement, secure token management, and robust audit mechanisms. The guide offers actionable strategies for deployment across bare metal, virtual, and containerized environments, supplying pragmatic advice on configuration management, seamless upgrades, high availability, disaster recovery, and advanced diagnostics. Specialized chapters address customization, extensibility, and real-world integration with external IAM systems, ensuring that Keystone can be tailored to meet the stringent security, compliance, and operational demands of any cloud environment.
Advanced topics—including federated identity, scalability strategies, security posture, multi-region reliability, and emerging practices such as zero-trust architectures and chaos engineering—are covered with clarity and depth. Drawing on lessons from production-scale case studies and involvement with the OpenStack community, the guide not only illuminates current best practices but also provides a forward-looking perspective on Keystone's evolving roadmap and its role in next-generation cloud identity management. Whether you are planning, building, or securing an enterprise OpenStack cloud, this reference empowers you to design and operate Keystone environments with confidence and precision.
