GCP Cloud CDN
ELI5 — The Vibe Check
Cloud CDN caches your content on Google's edge servers around the world. When a user in Tokyo requests your page, they get it from a nearby Google server instead of your origin in Virginia. It's like having mini copies of your app's assets strategically placed across the globe. Speed through proximity.
Real Talk
Google Cloud CDN uses Google's globally distributed edge points of presence to cache HTTP(S) content close to users. It integrates with Cloud Load Balancing, supports cache invalidation, signed URLs, and provides origin shielding. It leverages the same infrastructure that serves Google's own content.
