In the cloud-native era, the traffic routing and secure access of microservices architecture have gone beyond the traditional Kubernetes Ingress API. Cloud-native solutions provide more flexible, scalable, and secure ways to manage traffic both inside and outside the cluster.
For example, Service Mesh technologies like Istio and Linkerd provide rich traffic management features, including dynamic routing, circuit breaking, retries, timeouts, and more. They also have built-in secure service-to-service authentication and encrypted communication, significantly improving the overall system security.
Additionally, modern API gateways like Cilium can seamlessly integrate with Kubernetes, providing more fine-grained routing rules, load balancing, monitoring, and other functionalities. They can serve as the unified entry point for the cluster, simplifying the management of external access.
