EC2 Auto Scaling

Automatically adds/removes EC2 instances based on health checks and metrics to match capacity to demand. No direct VM-level open-source equivalent outside a cloud provider's own API; closest analogue when workloads are containerized is the Kubernetes Cluster Autoscaler (node-level) paired with KEDA (event-driven pod scaling) — the most-used combination for the same "scale compute to match demand" goal in a self-managed/multi-cloud setup.
