FaaS-netes in Practice

**FaaS-netes in Practice: Building, Deploying, and Operating Serverless Workflows** is a practical guide to designing, deploying, and running serverless workloads on Kubernetes. It is written for cloud engineers, platform architects, and DevOps practitioners who want to understand how Function-as-a-Service fits into modern cloud-native systems. The book explains the core ideas behind serverless computing in Kubernetes, compares leading open-source platforms such as Knative, OpenFaaS, Kubeless, and Fission, and shows how these technologies enable flexible, event-driven applications across enterprise and multi-cloud environments.

The book moves from fundamentals to hands-on implementation, covering function execution models, autoscaling, lifecycle management, and multi-tenancy. It also explores how to build reliable deployment pipelines with Helm, Kustomize, Terraform, and Crossplane, while addressing key operational concerns such as ingress, networking, observability, tracing, and service mesh integration. In addition, it provides practical guidance on security and governance, including secrets management, RBAC, artifact integrity, compliance, and tenant isolation, so teams can operate serverless platforms safely and at scale.

Beyond day-to-day operations, the book examines the performance, cost, and architecture challenges that shape real-world FaaS-netes environments. Topics include cold-start optimization, hybrid and multi-cluster deployments, edge serverless patterns, and emerging approaches such as WebAssembly. It concludes with real-world case studies and forward-looking insights into AI/ML-driven workflows and the future of Kubernetes-based serverless computing, making it a valuable reference for teams building production-ready serverless platforms.
