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.

External Secrets Operator

"External Secrets Operator (ESO) is a Kubernetes operator that integrates external secret management systems like AWS Secrets Manager, HashiCorp Vault, Google Secrets Manager, Azure Key Vault and many more. The operator reads information from external APIs and automatically injects the values into a Kubernetes Secret. ESO provides a user-friendly abstraction for the external API that stores the secrets for you. It allows you to manage access to the secret store for different tenants within your cluster and keeps the Kubernetes secrets in sync.

Akri

"Akri removes the work of finding, using, and monitoring the availability of the IoT devices around Kubernetes clusters. it provides an abstraction layer for device usage, handling the dynamic appearance and disappearance of IoT devices on the Edge. An operator simply applies an Akri Configuration to a cluster, specifying the Discovery Handler (most commonly a protocol) that should be used to discover the devices, and the pod that should be deployed upon discovery. Then Akri does the rest. An operator can also allow multiple nodes to use an IoT device, thereby providing high availability in the case where a node goes offline. Furthermore, Akri will automatically create a Kubernetes service for each type of device, removing the need for an application to track the state of pods or nodes."
