## What it is
KEDA is a Kubernetes-based event-driven autoscaler that scales any container workload based on the number of events needing processing, using a dedicated custom resource definition and 70+ built-in scalers. It acts as a Kubernetes Metrics Server, integrates with the Horizontal Pod Autoscaler, and supports scaling to and from zero.

## Use cases
- scale kubernetes deployments based on kafka queue depth
- autoscale pods to zero when there is no traffic
- scale workers based on rabbitmq or aws sqs queue length
- event-driven autoscaling for kubernetes jobs
- run and scale azure functions on kubernetes
- replace manual hpa configuration with event-based scaling rules

## When to choose
- you need fine-grained, event-driven autoscaling including scale-to-zero for kubernetes workloads
- you want to scale based on external event sources like queues, streams, databases, or cloud metrics
- you need a vendor-agnostic scaler supporting many cloud providers and messaging systems
- you want to run azure functions on kubernetes in production

## When to avoid
- you only need simple CPU/memory-based autoscaling, which the built-in HPA already handles
- you are not running workloads on kubernetes
- you need full serverless function platforms rather than scaling existing containers
- you cannot add operators or CRDs to your cluster due to policy restrictions
