Gateway API, Kubernetes Multicluster Services(MCS) API, and NetworkPolicy API stand as the cornerstones of Kubernetes networking, each playing a pivotal role in shaping the way we manage and secure traffic within and across clusters.

Gateway API simplifies ingress configuration in Kubernetes, offering a unified approach for routing and load balancing.

Kubernetes MCS API provides a service-discovery mechanism in multiple-cluster environments.

NetworkPolicy API helps to safeguard your applications with policies that allow or deny communication between pods and services based on defined criteria.

In this talk, we will delve deep into the technical intricacies of harnessing these APIs using the Envoy Gateway and the Submariner project, showcasing real-world use cases that transcend the theoretical into the practical. Discover how to build a rock-solid, secure multi-tier ingress solution that scales effortlessly and ensures the seamless, secure flow of traffic across your clusters.
