Question

A media company runs a global external Application Load Balancer to serve its website. Static assets (images, CSS, JS) are stored in a Cloud Storage bucket, while dynamic API traffic must be routed to VM-based backends running in a managed instance group in us-central1 and europe-west1. The team wants a single anycast IP and URL map that directs '/static/*' requests to the bucket and all other requests to the VMs, with static assets cached at Google's edge. Which configuration meets these requirements?

Accepted Answer

Create a backend bucket (with Cloud CDN enabled) for the storage bucket and a backend service with the two instance groups as backends, then use a URL map with a path matcher sending '/static/*' to the backend bucket and the default route to the backend service.

Answer

Create two separate load balancers—one pointing at the bucket with Cloud CDN and one pointing at the instance groups—and use DNS weighting to split traffic between them.

Answer

Create a single backend service that includes both the Cloud Storage bucket and the instance groups as backends, enabling Cloud CDN on the backend service.

Answer

Create a backend service with the instance groups and attach the Cloud Storage bucket as a serverless NEG, then enable Cloud CDN on the serverless NEG.
