Google recently supported an organization that wanted to ๐™š๐™ญ๐™ฅ๐™ค๐™จ๐™š ๐™ž๐™ฉ๐™จ ๐™‚๐™ค๐™ค๐™œ๐™ก๐™š ๐™†๐™ช๐™—๐™š๐™ง๐™ฃ๐™š๐™ฉ๐™š๐™จ ๐™€๐™ฃ๐™œ๐™ž๐™ฃ๐™š (๐™‚๐™†๐™€) backend ๐™—๐™š๐™๐™ž๐™ฃ๐™™ ๐˜ผ๐™ฅ๐™ž๐™œ๐™š๐™š ๐™“. A ๐™ฆ๐™ช๐™ž๐™ฉ๐™š ๐™˜๐™ค๐™ข๐™ข๐™ค๐™ฃ ๐™–๐™ง๐™˜๐™๐™ž๐™ฉ๐™š๐™˜๐™ฉ๐™ช๐™ง๐™š, which most of the users delivering ๐™ข๐™ค๐™™๐™š๐™ง๐™ฃ ๐™ฌ๐™š๐™— ๐™–๐™ฅ๐™ฅ๐™ก๐™ž๐™˜๐™–๐™ฉ๐™ž๐™ค๐™ฃ๐™จ on Google Cloud tend to build upon.

You could connect ๐˜ผ๐™ฅ๐™ž๐™œ๐™š๐™š ๐™–๐™ฃ๐™™ ๐™‚๐™ค๐™ค๐™œ๐™ก๐™š ๐™†๐™ช๐™—๐™š๐™ง๐™ฃ๐™š๐™ฉ๐™š๐™จ ๐™€๐™ฃ๐™œ๐™ž๐™ฃ๐™š (๐™‚๐™†๐™€) backends so that you ๐™ฌ๐™ค๐™ฃโ€™๐™ฉ ๐™๐™–๐™ซ๐™š ๐™ฉ๐™ค ๐™ฅ๐™š๐™ง๐™›๐™ค๐™ง๐™ข ๐™‡7 ๐™ง๐™ค๐™ช๐™ฉ๐™ž๐™ฃ๐™œ in ๐™—๐™ค๐™ฉ๐™ ๐™˜๐™ค๐™ข๐™ฅ๐™ค๐™ฃ๐™š๐™ฃ๐™ฉ๐™จ.

This will likely help you to:
(1) โฑ๏ธ ๐™จ๐™–๐™ซ๐™š ๐™ฉ๐™ž๐™ข๐™š (managing way fewer configurations) and
(2) ๐Ÿš€ reach ๐™—๐™š๐™ฉ๐™ฉ๐™š๐™ง ๐™ฅ๐™š๐™ง๐™›๐™ค๐™ง๐™ข๐™–๐™ฃ๐™˜๐™š๐™จ.

When a request comes in, Apigee:
(1) reads the Target Endpoint value and
(2) queries Cloud DNS to get the IP of the application pod.
(3) reaches the pod directly, with no need for additional routing to be configured on the K8s cluster.
