What feature helps users cache content to improve loading speed?

The feature that helps users cache content to improve loading speed is Cloud CDN (Content Delivery Network). Cloud CDN leverages Google's globally distributed edge points of presence to cache HTTP(S) load balanced content close to users. This reduces latency because users can retrieve content from a nearby location instead of a central server that may be farther away. When users request content, Cloud CDN checks its cache to see if it has the requested data. If it's cached, it can deliver that data to the user without needing to go back to the origin server, significantly improving loading speeds.

By integrating with Google Cloud's load balancing, Cloud CDN can also automatically handle cache invalidation and provide features like SSL support, cache control, and security features to further enhance performance and reliability. This makes it particularly useful for applications like media streaming, website content delivery, and any scenario where quick data retrieval is essential for enhancing the user experience.
