What is this?
KEDA is a Kubernetes-based event driven autoscaling component — it automatically scales any container running in a Kubernetes cluster based on events.

Quickstarts and full documentation are at keda.sh.

Anywhere — KEDA runs on both cloud and edge Kubernetes clusters.Which event sources can it scale on?Any container running in Kubernetes can be scaled. The README ships quickstarts for RabbitMQ with Go, Azure Functions with Queues, Azure Functions with Kafka on OpenShift 4, and Azure Storage Queue ScaledJobs, plus more samples for other event sources.
