Learn KNATIVE with Real Code Examples
Updated Nov 25, 2025
Architecture
Built on top of Kubernetes
Serving layer for deployments and autoscaling
Eventing layer for routing events to services
Knative Build (deprecated) or Tekton Pipelines for CI/CD integration
Integration with Istio/Contour/Kourier for networking
Rendering Model
Client sends request/event -> Knative service
Knative Serving handles routing and scaling
Event triggers invoke appropriate service revisions
Service executes business logic
Response/event processed and logged back
Architectural Patterns
Kubernetes-native deployment
Serverless and event-driven design
Revision-based immutable services
Traffic routing and splitting
CloudEvents-based eventing system
Real World Architectures
Serverless APIs and microservices
Event-driven IoT backends
Cloud-native CI/CD pipelines
Message queue consumers
Multi-tenant scalable services
Design Principles

Scalability Guide
Use scale-to-zero for cost efficiency
Autoscale based on traffic or events
Deploy multiple revisions for canary testing
Integrate with horizontal pod autoscaler if needed
Monitor scaling with Prometheus/Grafana
Migration Guide
Migrate workloads from Lambda or OpenFaaS
Containerize applications
