Knative

Knative is an open-source framework that adds serverless capabilities to Kubernetes, providing tools for building, deploying, and managing cloud-native, event-driven applications. It offers high-level abstractions over Kubernetes, including Serving for deploying and autoscaling serverless workloads, and Eventing for handling events and building event-driven architectures. Knative automates tasks like networking, scaling to zero, and revision tracking, simplifying the development of serverless and event-driven applications.  

Key Components

• Knative Serving: Automates the deployment and scaling of serverless applications. It handles tasks like managing routes, configurations, and revisions, allowing services to automatically scale down to zero when not in use. 
• Knative Eventing: Provides tools to create event-driven applications. It connects event producers (sources) to event consumers (sinks), enabling applications to respond to events from various sources and build event-driven architectures. 
• Knative Build (or Functions): Automates the process of turning source code into container images. This component helps generate container images that are then used by the Serving component, streamlining the CI/CD process. 

Key Features:

• Serverless on Kubernetes: Brings serverless computing paradigms to the Kubernetes ecosystem, allowing developers to focus on code rather than infrastructure management. 
• Automated Autoscaling: Services can automatically scale up or down based on incoming traffic, including scaling to zero when not in use. 
• Revision Tracking: Manages different versions (revisions) of a service, enabling easy rollbacks and traffic splitting. 
• Event-Driven Architecture: Facilitates the creation of event-driven systems by providing standard APIs and components for routing and processing events.
