Knative: The Serverless Environment for Kubernetes Fans

This report introduces Knative, an open-source, Kubernetes- and Istio-based serverless framework, outlining its core components (Build, Eventing, Serving), benefits like cloud-agnostic flexibility and autoscaling, and the availability of managed offerings (e.g., GKE, IBM Cloud). It contrasts Knative with other Kubernetes-native serverless projects (Fission, Kubeless) and notes faster adoption due to leveraging widely used open-source components. The document also highlights security and operational considerations—such as automated builds and scale-to-zero potentially bypassing established controls—and recommends embedding runtime security (e.g., Aqua MicroEnforcer) to maintain visibility and policy enforcement across dynamic deployments.
