Unleashing the Power of Serverless on Kubernetes with Knative, Crossplane, Dapr & KEDA
summary
Demonstration shows a working voting app (cats vs dogs) composed of a UI, Redis, RabbitMQ, Postgres and a worker, built and deployed on GKE using Open Function which stitches buildpacks, a builder, and an image-from-Git flow. HTTP endpoints use Knative serving with a 90s idle downscale, a ~1s cold start via activator and sidecar proxy. App logic uses Dapr sidecar for state, pub/sub and portability across providers, while infra provisioning is automated with Crossplane compositions to create Cloud SQL and message broker resources.
