You need a highly available, global, low-latency, low-management solution to serve static content. Which storage and serving configuration best meets these goals?

A multi-regional Cloud Storage bucket provides high availability and low latency globally by replicating data across multiple regions. This eliminates the need for manual replication or instance group management. Combining this with an external HTTP(S) load balancer and Cloud CDN further optimizes for low latency by caching content at edge locations close to users, and provides a global entry point. The options involving managed or unmanaged instance groups introduce unnecessary compute management overhead for static content. While Cloud CDN is beneficial in these scenarios, the underlying storage and serving mechanism is more complex than a Cloud Storage bucket. A regional Cloud Storage bucket would not provide the same level of global availability and low latency as a multi-regional one.
