OpenFaaS Engineering Guide
"OpenFaaS Engineering Guide" The "OpenFaaS Engineering Guide" is the definitive technical resource for platform engineers, developers, and architects seeking to master serverless deployments on cloud-native infrastructure. This comprehensive volume delivers a deep exploration of OpenFaaS, from first principles to nuanced production practices. Readers are guided through the architecture of OpenFaaS, contrasting its design with alternative FaaS platforms such as AWS Lambda and Knative, and exploring extensibility mechanisms, lifecycle orchestration, and data flow patterns. With a clear emphasis on real-world application, the guide empowers professionals to understand not just how OpenFaaS works, but why its architectural choices matter in modern distributed systems. Covering every stage of the platform journey, the guide details robust installation methods, infrastructure codification with Terraform, CI/CD best practices, and scaling strategies for high availability and reliability. Developers will gain actionable insights into function development across multiple languages, secure configuration, test automation, and performance tuning, while advanced sections unlock expertise in asynchronous workloads, event-driven architectures, and seamless integrations with message brokers and external APIs. Comprehensive guidance on security, compliance, monitoring, and resilience ensures operational excellence in even the most demanding enterprise and regulated environments. Extending its value beyond platform fundamentals, the "OpenFaaS Engineering Guide" provides thought leadership on performance optimization, observability, workflow orchestration, and complex hybrid integrations, including IoT and edge scenarios. Insightful case studies and practical pipeline examples are paired with advanced topics such as distributed tracing, chaos engineering, and sustainable software practices. Looking to the future, the guide explores the OpenFaaS roadmap, emerging cloud native trends, and the evolving role of serverless in distributed systems—making this an essential, forward-looking handbook for any professional intent on maximizing the impact of OpenFaaS in organizational and technological transformation.
OpenFaaS on Kubernetes: Architecture and Implementation
"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.
