Spectacular Acceleration and Global Coverage
In order to allow your published content to reach users faster, Tencent Cloud CDN has set up more than 1300 nodes across the nation, covering mainstream ISPs such as China Mobile, China Unicom and China Telecom as well as many medium and small-sized ISPs such as China Tietong and Great Wall Broadband. Standalone server on each node has a performance up to double-hundred-million and the total node bandwidth reaches over 120T, thus perfectly solving the problem of high access latency of user and instability caused by such factors as geographical location, network and origin server's performance.
Nodes in Mainland China
Tencent Cloud CDN provides more than 200 overseas nodes with a coverage of more than 50 countries and regions across the globe to allow your business to go global seamlessly.
Intelligent Scheduling and Link Optimization
When your user requests for resources, the request may not be transmitted via the optimal access route due to such factors as network, geographical location or bandwidth. Tencent Cloud CDN, through the real-time monitoring of the links across the network and by using the self-developed GSLB scheduling system and intelligent routing technology, optimizes user's access experience in the following three ways.
With Tencent Cloud's GSLB scheduling system, your users' requests will be allocated to the nearest, best CDN node to ensure that users can quickly get what they need.
When the request for the content needed is sent to the allocated node, the node needs to go back to the origin server to get it. Tencent Cloud CDN will select for you the optimal network link to ensure a rapid access to the content based on the real-time status monitoring across network and intelligent routing technology.
If your user initiates a dynamic request, for example, makes a login, such a request cannot be accelerated by the node and it needs to be directly transmitted to the origin server. Tencent Cloud CDN also provides the optimal network link for such requests to effectively bypass links with poor quality or congested links, improving the speed by up to 20%.
High Security and Transparency, Comprehensive Protection
With the presence of enormous security risks in public network environment, your origin server may be subject to malicious network attacks, resulting in the failure to provide services for users normally or unnecessary losses caused by malicious cheating for your published content. In order to guarantee your business security, Tencent Cloud CDN provides an all-round protection for your business in the following three aspects.
Each node of Tencent Cloud CDN boasts anti-DDOS capability. In combination with the independently developed malicious attack filter module, these nodes can effectively defense against DDOS and CC attacks to ensure the normal operation of your business.
Tencent Cloud CDN supports HTTPS transmission of all nodes across the network. If your business has a high security requirement and has a certificate, it can be directly uploaded to the CDN node for deployment. Both the user request sent to node and back-to-origin request sent from node will be encrypted to ensure data security. If you have no certificate, Tencent Cloud provides you with a free third-party DV certificate that allows one-click deployment to make the connection more secure.
Anti-hijacking of Domain Name
In order to prevent your domain name from being hijacked in the process of revolution and thus failing to be resolved to the optimal access node, Tencent Cloud CDN provides HTTP DNS Express Service solution. In this way, your domain name will be resolved more rapidly through the PUBLIC DNS to avoid being hijacked maliciously.
