Component overview
ACS Knative is fully compatible with community Knative and is deeply integrated with the Alibaba Cloud product ecosystem. For more information, see Knative overview.
Knative consists of the following core components:
| Component | Description |
|---|---|
| Knative Serving | Manages serverless workloads. Supports serverless deployment, version management, and canary releases. Supports pod auto scaling based on resource requests. Scales pods to zero when no traffic is processed. |
| Knative Eventing | Provides event management capabilities. Allows you to interface with external event sources, register and subscribe to events, and filter events. Decouples event producers from event consumers. |
| Knative Functions | Allows you to create, build, and deploy Knative Services efficiently. Deploy stateless, event-driven functions to a Kubernetes cluster without deep knowledge of the underlying technology stack. |
