    Global Intelligent Scheduling

    When accessing resources, a variety of factors including the ISP network, client region, and the network bandwidth of the IDC origin server might affect the response time and user experience.

    Through real-time monitoring of the linkages across the entire network and leveraging Tencent Cloud's self-designed GSLB scheduling system and intelligent routing technology, CDN schedules users' access requests to the optimal edge nodes for acceleration. This ensures quick and stable resource access for users.

    Quick Configuration

    You can use CDN to accelerate your services through a simple and quick configuration process, with no additional modification required on your end.

    After registering your Tencent Cloud account and completing identity verification, you can activate the CDN service. Prepayment is not required. Add your business domain name on the CDN Console and wait for about 5 minutes for the domain name configuration to be distributed to cache nodes across the entire network. During this process, as the acceleration service has not taken effect yet, your business will not be affected.

    When enabling the acceleration service, you need to modify the CNAME resolution configuration through your domain name service provider. Acceleration service will take effect when the DNS takes effect.

    A Variety of Features

    CDN comes with an easy-to-use, full-featured console where you can change the configuration items and view monitoring data as needed:

    Domain management

    • You can add, delete, activate, and deactivate domain names.
    • You can switch acceleration regions and select "Mainland China", "Outside Mainland China", or "Global" for the acceleration scope.
    • You can customize the domain name list page to display, filter, and query configuration items.

    Domain configuration

    • You can configure an external origin server (IP list or domain names) or use COS as an origin server. Round robin, weighted origin-pull, and hot backup of origin server are supported.
    • You can configure custom access control policies such as referer blacklist/whitelist, IP blacklist/whitelist, timestamp hotlink protection, and IP access frequency limit.
    • You can customize the expiration time of node cache, status code cache, and HTTP header cache.

The statistics can be filtered by project, domain name, province, ISP, and protocol to present a comprehensive view of service status.
    • CDN supports real-time monitoring of the origin-pull bandwidth, traffic, number of requests, failure rate, and all status codes generated by origin-pull requests at a granularity of 1 minute.
