Google Cloud CDN
Introduction
Google Cloud CDN (Content Delivery Network) is a service that accelerates content delivery for websites and applications served out of Google Cloud. It utilizes Google's globally distributed edge points of presence to cache content close to users, improving load times and reducing latency.
What is CDN?
A CDN is a network of servers strategically distributed across various locations that deliver web content to users based on their geographic location. By caching content at edge locations, CDNs help decrease load times and improve overall user experience.
