Question

Your company hosts a large library of static marketing assets (images, PDFs, videos) in a Cloud Storage bucket. You want to serve these assets globally with low latency and caching, using a global external Application Load Balancer with Cloud CDN enabled. The team wants the simplest configuration that requires no compute instances and lets Cloud CDN cache directly from the bucket. Which backend configuration should you use?

Accepted Answer

Create a backend bucket that references the Cloud Storage bucket and enable Cloud CDN on the backend bucket.

Answer

Create a backend service with a managed instance group of NGINX proxies that read from the bucket, then enable Cloud CDN on the backend service.

Answer

Create an internet network endpoint group (NEG) pointing to storage.googleapis.com and attach it to a backend service with Cloud CDN.

Answer

Create a serverless NEG backed by a Cloud Run service that streams objects from the bucket, then enable Cloud CDN.
