Frequently Asked Questions about Knative
What is Knative?
Knative is a Kubernetes-based platform that extends Kubernetes to build, deploy, and manage modern serverless workloads. It simplifies running containerized applications with automatic scaling, eventing, and routing capabilities.
What are the primary use cases for Knative?
Serverless applications on Kubernetes. Event-driven microservices. Automatic scaling workloads. Routing and traffic management for services. Integrating with cloud-native CI/CD pipelines
What are the strengths of Knative?
Automatic scaling reduces resource usage. Supports event-driven serverless architecture. Seamless Kubernetes integration. Flexible routing and traffic management. Extensible and cloud-native friendly
What are the limitations of Knative?
Requires Kubernetes knowledge. Complex setup for beginners. Dependent on cluster resources and networking. Debugging can be more challenging than traditional apps. Limited built-in tooling compared to managed serverless platforms
