This document describes how to use Tencent Cloud CDN to accelerate access to COS.
By delivering resources to high numbers of globally deployed cache nodes and leveraging Tencent's independently developed GSLB scheduling system, CDN enables nearby access to required resources for end users. This reduces access delays caused by network congestion, distance, and ISP issues and effectively improves the download speed, responsiveness, and user experience.
You can store all your static resources such as static scripts, audio/video files, images, and attachments in standard storage in COS, which features unlimited capacity and high-frequency reads/writes to provide scalable and reliable storage for static resources and reduce pressure on resource servers.
CDN can accelerate global delivery of static resources such as static scripts, audio/video files, images, and attachments stored in COS. With CDN's global cache nodes and scheduling capabilities, frequently requested resources can be delivered to edge servers in advance. When they are accessed or downloaded by end users, the cached resources on a nearby node will be returned. This reduces both pressure on the origin server as well as transfer delay, significantly improving the user experience.
Tencent Cloud Enterprise Content Delivery Network (ECDN) can be used to accelerate the delivery of dynamic/static resources or dynamic resources stored in COS.
CDN acceleration can be implemented for COS in the following ways:
