Alibaba Cloud SCDN security acceleration The product is a CDN service provided by Alibaba Cloud for ECS users with security protection capabilities. On the basis of AliCloud CDN, it intelligently judges whether it is an attack, and intelligently throws DDoS attack requests to advanced anti DDoS IP cleaning, while real users' requests are normally obtained from the acceleration node to meet the requirements of both acceleration and security. Weieis blog mentioned before The difference between Alibaba Cloud SCDN and CDN products , which is not detailed enough. Let's talk about it in detail with the help of this article.
Traditional CDN acceleration has the most basic DDoS and CC attack defense capabilities, but it is powerless in case of large-scale attacks. Frequently encountering large-scale network attack ides, such as games, finance, government and enterprise security, e-commerce, medical and other industries, Alibaba Cloud SCDN needs to be able to defend against large traffic attacks and consider the need for acceleration. At this time, Alibaba Cloud SCDN needs to integrate Alibaba Cloud Shield's defense strategies to provide an overall solution for security and acceleration in a set of products. To put it simply, Alibaba Cloud SCDN integrates security and acceleration together, saving time and ensuring security.
The following figure shows the architecture of Alibaba Cloud SCDN. As can be seen from the figure, if it is a hacker's behavior, it will be cleaned by Anti D, and normal visitors will normally open the website. That is, both safety and acceleration are considered.

As long as the status is normal, the addition is successful. If the audit fails, the reason shall be found out or a work order shall be issued for inquiry.
3、 Configure CNAME
The domain name has not been added yet. To use SCDN security acceleration, you need to add CNAME records. Point the acceleration domain name obtained here to the CNAME address, so that access requests can be forwarded to SCDN nodes to achieve security acceleration. This operation is easy for skilled people to add directly. For newcomers, there is still a need for a tutorial.
Get the accelerated domain name in CNAME of SCDN domain name management.
4、 Follow the steps below. The following is an example of Alibaba Cloud domain names. The record type is CNAME, the host record is the prefix of the acceleration domain name, and the record value is the CNAME value copied from the SCDN console, that is, the CNAME value obtained in the above step.
After confirmation, the CNAME configuration is completed, and the SCDN service will take effect immediately after the CNAME record takes effect.
5、 How to check whether the SCDN has taken effect?
After configuring CNAME, different service providers have different effective times. New records will become effective immediately, while modified records will take a long time. You can ping or dig the acceleration domain name you added. If you switch to the domain name of *. * scdn *. com, the SCDN function will take effect.
