keda
KEDA is a Kubernetes-based Event Driven Autoscaling component. It provides event driven scale for any container running in Kubernetes
KEDA (Kubernetes Event-Driven Autoscaling) extends Kubernetes’ scaling capabilities by allowing workloads to scale based on event-driven metrics such as message queue length, HTTP requests, or custom Prometheus queries. Unlike traditional Horizontal Pod Autoscalers (HPA) that rely solely on CPU or memory metrics, KEDA provides fine-grained control and adaptability to diverse application needs. For developers using SpinKube, KEDA enables efficient scaling of Spin apps based on application-specific metrics, making it easier to handle event-driven workloads in a Kubernetes environment. KEDA has a vast amount of built-in scalers to simplify integration with services running inside and outside of Kubernetes itself.

AutoSpotting
Saves up to 90% of AWS EC2 costs by automating the use of spot instances on existing AutoScaling groups. Installs in minutes using CloudFormation or Terraform. Convenient to deploy at scale using StackSets. Uses tagging to avoid launch configuration changes. Automated spot termination handling. Reliable fallback to on-demand instances.
