KEDA: Event Driven and Serverless Containers in Kubernetes

on YouTube ↗36m

" summary

KEDA 1.0 is an open source Kubernetes operator that provides event-driven autoscaling by feeding queue and stream metrics into the HPA, supporting Kafka, RabbitMQ, Azure Event Hubs, Redis, AWS and GCP adapters. The operator (written in Go) uses a ScaledObject CRD, can scale to zero, and demonstrates creating jobs per event for long-running work. A demo publishes 1,000 messages to RabbitMQ and the deployment spikes to eight replicas then returns to zero; project ships as 1.0 release and targets CNCF onboarding.
