Acceleration Effect

All users across the globe access the nearest CDN point of presence (PoP) to quickly get what they want.

Users in the Chinese mainland access the nearest PoP in the Chinese mainland. They will experience notable acceleration.

Users outside the Chinese mainland also access PoPs in the Chinese mainland. However, due to cross-border network conditions, the acceleration will not be as noticeable as it is for access from within the Chinese mainland. In the worst-case scenario, your domain name may become inaccessible.

Users outside the Chinese mainland access the nearest PoP outside the Chinese mainland. They will experience notable acceleration.

Users in the Chinese mainland also access PoPs outside the Chinese mainland. However, due to cross-border network conditions, the acceleration will not be as noticeable as it is for access from within the Chinese mainland. In the worst-case scenario, your domain name may become inaccessible.

Getting Started with CDN in 3 Steps

Enabling CDN

Enable CDN before using it.

Adding a Domain Name

To use CDN to accelerate your business, add the domain name of your site to CDN and use your site as the origin server.

Adding a CNAME Record on Huawei Cloud DNS

The system automatically assigns a CNAME record to the domain name you added. Add this record to the record sets of your DNS provider, so that all requests to your domain name will be redirected to CDN PoPs.

Best Practices

Accelerating OBS Resources

Cache resources to CDN PoPs, so that users can obtain the latest resources from the nearest CDN PoP.

Accelerating Resources Protected by WAF

If your websites have high requirements on security and acceleration, associate Huawei Cloud CDN with WAF to accelerate websites and defend against web attacks.

Accelerating ECS Resources

Huawei Cloud CDN can accelerate websites to deliver a better user experience. Use CDN to accelerate access to your ECSs to improve user experience at low costs.

Setting the Maximum Cache Age

CDN caches origin content on globally distributed PoPs so that users can obtain the content from nearby PoPs. Set the TTL for caching origin content on PoPs as required.

Improving the Cache Hit Ratio

If the CDN cache hit ratio is low, the pressure on the origin server is high and the static resource access efficiency is low. Select an optimization policy based on the cause of the low cache hit ratio to improve the cache hit ratio.

Obtaining Real IP Addresses of Users

After a website is connected to CDN for acceleration, IP addresses obtained by the origin server from IP address headers are not the real IP addresses of users. Configure your web server to obtain the real IP addresses of users.
