Kubernetes Made Simple: Part 6 — Why do we need Gateway API?

In the sixth part of the 'Kubernetes Made Simple' series, the author explores the purpose of the Gateway API, which is designed to supplement or replace the traditional Ingress resource. The focus is on architectural differences: while Ingress often becomes a bottleneck due to limited configuration options, the Gateway API offers a more flexible model for separating responsibilities. Using practical examples, the article demonstrates how Gateway and HTTPRoute objects allow for the decoupling of cluster entry point management from traffic routing configuration. The author explains the role of GatewayClass and shows why this model is particularly effective in large organizations where infrastructure and application deployment are handled by different teams. This solution provides better scalability and simplifies the administration of complex network configurations in Kubernetes, making the traffic management process more transparent and structured for DevOps engineers.
