Writing Serverless Applications with Quarkus and Knative
Talkat JCON Europe 2023 · on Wednesday, 2023-06-21· at 14:00· Cinema 5, Im Mediapark 1, 50670 Köln, Germany·
summary
Quarkus shifts dependency scanning and wiring to build-time boot and can produce native images via Mandrel/GraalVM, cutting JVM cold-starts to milliseconds (demo log shows ~30 ms). Knative on OpenShift enables scale-to-zero serving and CloudEvents-driven Eventing; switching the OpenShift Sandbox reduced running footprints that previously consumed ~7 GB RAM and 15 GB storage. A demo voting app uses Quarkus + Camel + Kafka + Postgres, autoscaling from zero to ~14 pods and handling ~1,700 votes for the top option.
