Knative Serving is the core component of Knative. It provides serverless workload management capabilities. Knative Serving enables serverless deployment, version management, and canary releases for your applications. Knative Serving also supports pod auto scaling based on resource requests. If no traffic is processed, the number of pods is scaled to zero. We recommend that you update the Knative Serving component in the console at your earliest convenience to benefit from new features and fix bugs.
