Open Policy Agent
Stop using a different policy language, policy model, and policy API for every product and service you use. Use OPA for a unified toolset and framework for policy across the cloud native stack. Whether for one service or for all your services, use OPA to decouple policy from the service's code so you can release, analyze, and review policies (which security and compliance teams love) without sacrificing availability or performance.

KEDA
KEDA is a Kubernetes-based event-driven autoscaler. KEDA determines how any container in Kubernetes should be scaled based on the number of events that need to be processed. KEDA is a single-purpose and lightweight component that can be added to any Kubernetes cluster. It works alongside standard Kubernetes components like the Horizontal Pod Autoscaler and can extend functionality without overwriting or duplication. With KEDA you can specify the that apps you want to scale in an event-driven way while other apps continue to function. This makes KEDA a flexible and safe option to run alongside other Kubernetes applications and frameworks.
