Homemade Serverless: Making it from Scratch

on YouTube ↗54m

" summary

Shows how a Java payment microservice runs on an OpenShift Kubernetes cluster, wrapped by KNative serving and eventing to turn Kafka order messages into on‑demand handlers. The demo builds a container image into the cluster registry, attaches a Kafka source to the KNative service, and proves scale to zero and fast spin‑up (100 concurrent requests with concurrency=2 yields ~50 pods). A native compilation cuts startup time, and KNative handles revisions, traffic splitting (50/50) and concurrency limits versus AWS Lambda.
