Building-permits needs many HTTP apps reachable on one shared external entrypoint and IP-friendly hostname routing. Why choose Ingress (or Gateway API) over one LoadBalancer Service per app?
Select an answer to reveal the explanation.
Short Explanation
One shared front desk beats renting a separate revolving door (cloud LB) for every tiny app. Ingress or Gateway API multiplex HTTP hosts and paths on a common entrypoint.
Full Explanation
A LoadBalancer Service typically provisions an L4 (or simple) external address per Service and does not by itself offer rich shared HTTP host/path multiplexing. Ingress and Gateway API exist to share edge entrypoints across many HTTP applications. They complement Services; they do not replace ClusterIP or kube-proxy.
