KEDA (Kubernetes Event-Driven Autoscaling)
CNCF project that scales Kubernetes workloads (including to zero) based on external event sources — queue depth, Kafka lag, cron schedules — rather than just CPU/memory. Paired with the Kubernetes Cluster Autoscaler as the most-used open-source alternative to EC2_Auto_Scaling/AWS_Auto_Scaling in containerized environments.
