This text discusses the deployment of Envoy as an API Gateway for microservices using Ambassador. It introduces Edge Stack, a Kubernetes-native API Gateway that simplifies configuration changes and integrates with Istio. The setup process involves creating a service for Edge Stack and deploying it as a Kubernetes deployment. Once deployed, users can access their microservices through the AMBASSADORURL. Diagnostics are also provided to give insight into Envoy's configuration management.
