Kurzbeschreibung des Verlags

**OpenFaaS Template Engineering: Building Reusable Serverless Functions with Confidence** is a practical guide for cloud engineers, DevOps professionals, and software architects who want to design, customize, and operate high-quality serverless functions with OpenFaaS. It explains the core principles of function-driven development in modern serverless environments, with clear coverage of OpenFaaS architecture, template lifecycle, and deployment patterns across Kubernetes and Docker Swarm. Readers will gain a solid understanding of how to build reliable, maintainable, and portable function templates that support real-world production workloads.

The book goes deep into template engineering, showing how to structure templates effectively, manage dependencies, craft efficient Dockerfiles, and tune functions for performance and scalability. It also explores advanced topics such as multi-architecture builds, runtime optimization, observability, and multi-tenancy, helping teams create reusable templates that can be adapted across projects and platforms. Throughout, the emphasis is on practical implementation and engineering discipline, enabling readers to move from experimentation to repeatable, production-ready serverless development.

In addition, *OpenFaaS Template Engineering* addresses the operational realities of secure and compliant deployments, including supply chain integrity, runtime isolation, audit logging, and governance. Real-world examples and case studies demonstrate how OpenFaaS templates can support data analytics, IoT, enterprise security, legacy modernization, and machine learning workflows. Whether building for hybrid cloud, edge environments, or tightly controlled enterprise systems, this book provides the knowledge and patterns needed to create reusable serverless functions with confidence.
