Evolving Kubernetes Networking: An Overview of the Gateway API

Abstract

Kubernetes has greatly evolved since its foundation and, in its own regard, is the de facto standard of container orchestration. This journey has constantly been marked by the addition of new features and improvements that continuously help cater to the growing needs of modern application deployments. A major step in this regard goes toward the implementation of the Gateway API, which tends to provide a smooth and easy way of serving services over communication technologies. That is to say, the Gateway API has a uniform way and mechanism to deal with requests as an intermediary in handling incoming traffic.Gateway API is one step toward driving away all those previously associated challenges of transactions in distributed, disparate environments. It functions concurrently with other products toward improving flexibility and efficiency in deploying Kubernetes. This paper discusses the design, integration, and implementation of Gateway API on Kubernetes; its implications on networking; and, most importantly, how it may keep improving containerized application management capacity.
