Summary

Edge Stack is a powerful Kubernetes-native API Gateway that provides advanced health checking configuration options to ensure services are healthy and prevent users from seeing errors. It supports gRPC and HTTP applications, making requests against the configured endpoint to determine which pods are healthy and which ones need a break from incoming traffic. Health checks can be configured using custom resources in Edge Stack, allowing for more advanced load balancing configurations such as active health checking. This feature is particularly effective during the shutdown phase of a Pod, giving it time to finish any ongoing processing and connection cleanup without getting new requests or being killed immediately by Kubernetes.
