Function as a Service (FaaS) remains at the core of the serverless movement. Kubernetes is best placed to bring serverless functions and conventional microservices together. This book has been written for admins who currently run their workloads in Kubernetes clusters and are interested in further leveraging their hardware/clusters to run.
