## What it is
Knative is a Kubernetes-based platform providing middleware components for building, deploying, and managing serverless workloads, comprising Serving (request-driven, scale-to-zero containers) and Eventing (CloudEvents-based event routing). It includes a Functions model with a func CLI for deploying stateless functions without deep Kubernetes knowledge.

## Use cases
- deploy serverless containers on kubernetes
- scale pods down to zero when idle
- build event-driven applications with cloud events
- deploy functions without writing dockerfiles
- split traffic between revisions of a service
- run a self-hosted serverless platform on my own cluster
- route events from producers to consumers on kubernetes

## When to choose
- you run Kubernetes and want serverless scale-to-zero semantics without vendor lock-in
- you need event-driven architecture with standardized CloudEvents routing
- you want simpler deployment abstractions on top of raw Kubernetes objects
- you need fine-grained autoscaling and traffic splitting between revisions

## When to avoid
- you don't operate a Kubernetes cluster or want fully managed FaaS like AWS Lambda
- your workloads are long-running and stateful rather than request-driven
- you want a lightweight setup without the operational overhead of installing CRDs and networking layers
- cold-start latency is unacceptable for your latency-sensitive services
