Knative is an open-source, Kubernetes-based platform designed to simplify the building, deployment, and management of modern serverless workloads. It provides a set of core components and abstractions that enable developers to focus on writing code while Knative takes care of the underlying infrastructure and scaling concerns.

• **Serverless Workloads:** Knative allows you to deploy and run serverless applications and functions on Kubernetes, abstracting away the complexities of infrastructure management and scaling.
• **Scale to Zero:** One of Knative's standout features is its ability to scale applications down to zero instances when there's no incoming traffic, reducing resource consumption and costs.
• **Autoscaling:** Knative can automatically scale your applications up or down based on demand, ensuring optimal resource utilization and responsiveness.
• **Build:** Knative provides a build component to automate the building of container images from source code, streamlining the development and deployment process.
• **Eventing:** The eventing component enables event-driven architectures, allowing you to trigger functions or services based on events from various sources.
• **Serving:** The serving component manages the deployment and routing of your serverless workloads, handling request-driven scaling and traffic management.

• **Focus on Code:** Knative empowers developers to concentrate on writing application logic without worrying about infrastructure provisioning and scaling.
• **Cost Efficiency:** Scale-to-zero capabilities minimize resource consumption and costs by only running instances when needed.
• **Improved Performance:** Knative's autoscaling ensures that your applications can handle varying levels of traffic without performance degradation.
• **Simplified Deployment:** Knative streamlines the deployment of serverless workloads, providing a consistent and Kubernetes-native experience.
• **Event-Driven Architectures:** The eventing component enables the development of loosely coupled, event-driven applications.

While Knative relies heavily on Kubernetes manifests and configurations, here's a simplified example of a Knative Service definition:

```yaml apiVersion: serving.knative.dev/v1 kind: Service metadata:

 name: my-service

 template:
   spec:
     containers:
     - image: my-org/my-app:latest

This configuration defines a Knative Service named “my-service” that will deploy and manage a containerized application using the specified image. Knative will handle the scaling, routing, and other operational aspects based on incoming traffic and event triggers.
