Knative is an open source serverless framework built on Kubernetes. It provides a cloud-native, cross-platform standard for serverless orchestration. Knative Serving is the core component of Knative. It manages serverless workloads, provides features such as application deployment and version control, and can scale application instances down to zero when there is no service traffic. ACS Knative provides a fully managed Serving component. This topic describes the release history of the Knative Serving component.
Component overview
While fully compatible with community Knative, ACS Knative is deeply integrated with the Alibaba Cloud product ecosystem to enhance its capabilities and offer a wider range of solutions. For more information about Knative, see Knative overview.

Knative consists the following core components, which provide different features:
Knative Serving: 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.
Knative Eventing: provides event management capabilities, which allow you to interface with external event sources, register and subscribe to events, and filter events. The event system decouples event producers and event consumers.
Knative Functions: allows you to create, build, and deploy Knative Services in an efficient manner. You can deploy stateless, event-driven functions as Knative Services to a Kubernetes cluster by using Knative Functions without the need to have a deep understanding of the underlying technology stack, such as Kubernetes, containers, and Knative.
