In a detailed exploration of integrating service meshes with external access, the document outlines the process of exposing Kubernetes-based services securely and reliably using Istio and Kong Istio API Gateway. It emphasizes the importance of managing ingress for configuration and operations, including authentication, observability, and encryption. The tutorial demonstrates the installation and deployment of Istio and Kong Istio Gateway using Helm Charts, followed by testing with the Insomnia tool. It also covers deploying the BookInfo application to illustrate traffic routing and user simulation, supported by observability tools like Prometheus, Jaeger, and Kiali. The guide further explores the flexibility offered by traffic policies and rate-limiting plugins, showcasing how Kong's plugins can enhance control and security. The narrative concludes by encouraging further exploration of Kong's features, including its Developer Portal and API analytics, for optimizing Istio clusters.
