Networking / API gateway

Component Description [#component-description]

`APISIX` was an API gateway used in the Runtime layer to expose, route, and protect platform traffic in earlier versions of the platform.

Why It Was Used [#why-it-was-used]

In previous versions of BullSequana AI, APISIX served as the controlled entry point for services and APIs, centralizing routing, traffic policies, and authentication integrations. It has been replaced by `Gateway API` (`Envoy Gateway`), which provides a Kubernetes-native routing model based on the Gateway API specification.
