"OpenFaaS on Kubernetes: Architecture and Implementation"
"OpenFaaS on Kubernetes: Architecture and Implementation" provides a comprehensive and authoritative exploration of deploying and managing OpenFaaS—one of the leading open-source serverless frameworks—on Kubernetes. The book begins by illuminating the evolution of serverless computing, establishing OpenFaaS's niche within an ever-expanding landscape that includes platforms such as AWS Lambda and Google Cloud Functions. Readers are guided through the motivations and technical advantages of adopting OpenFaaS on Kubernetes, while also gaining a solid grasp of Function-as-a-Service (FaaS) principles, event-driven architectures, and the unique integration challenges present in cloud-native environments.
Delving deeper, the book offers a robust walkthrough of Kubernetes fundamentals tailored for OpenFaaS operators, including core resource management, advanced networking, security practices, and multi-tenancy. A detailed architectural breakdown reveals how OpenFaaS leverages Kubernetes primitives, CRDs, and pluggable eventing systems to deliver scalability, resilience, and modularity. Essential operational topics—such as deploying high-availability clusters, securing gateways and data, establishing observability stacks, and lifecycle management—are covered with clarity and depth. Comprehensive function development workflows, CI/CD integration, debugging, disaster recovery, and performance optimization empower teams to build, deploy, and manage serverless workloads with confidence.
Recognizing the diverse applications and challenges of modern cloud-native workloads, the book surveys real-world use cases spanning data processing, machine learning inference, multi-cloud strategies, IoT, and edge computing. Security and compliance are examined in detail, from container hardening to policy enforcement and governance. The final chapters celebrate the vibrancy of the OpenFaaS community and ecosystem, address open research questions, and reflect on emerging trends in serverless and Kubernetes innovation. Whether you're a developer, architect, or operator, this book serves as your essential guide to mastering OpenFaaS in production Kubernetes environments.
