ApsaraVideo VOD allows you to accelerate content delivery by using Alibaba Cloud CDN. This topic describes the requirements for domain names that you want to add to ApsaraVideo VOD and related limits. Before you add a domain name to ApsaraVideo VOD, you must make sure that the domain name meets the relevant compliance requirements. This prevents losses caused by non-compliance.

Domain admission process

1
  1. Log on to the Alibaba Cloud official website. In the left-side navigation pane of the account center, click Real-name Registration. On the page that appears, complete the real-name verification as prompted.
  2. Apply for an Internet content provider (ICP) filing from the Ministry of Industry and Information Technology (MIIT) of China. We recommend that you use the Alibaba Cloud ICP Filing system.
  3. Review the content saved on the origin server of the accelerated domain name. You can specify an Object Storage Service (OSS) bucket or a bucket allocated to ApsaraVideo VOD as the origin server. If the content of your origin server is not stored on Alibaba Cloud, you must submit a request on Yida before you add the domain name to ApsaraVideo VOD.
  4. Add a CNAME record for your domain name at your DNS service provider. This ensures that your domain name is mapped to the CNAME that is generated in ApsaraVideo VOD. For more information, see Add a CNAME record in Alibaba Cloud DNS.
Note
  • If your origin server is deployed on an ECS instance, we recommend that you reserve at least 20% of your overall workloads for the server.
  • Make sure that the security software settings of the origin server allow the cache nodes of ApsaraVideo VOD to access the origin server.
  • Make sure that all requests are redirected to the origin server if the ApsaraVideo VOD service is stopped.
  • After a domain name is added to ApsaraVideo VOD, you cannot use the domain name to access resources in ApsaraVideo VOD until you add a CNAME record.

Content moderation

All accelerated domain names that are added to ApsaraVideo VOD must be reviewed. The accelerated domain names that cannot be added to ApsaraVideo VOD include but are not limited to the following types:

  • Domain names that cannot be accessed or do not contain valid information

  • Domain names of peer-to-peer (P2P) lending websites
  • Domain names of unofficial lottery websites
  • Domain names of unlicensed and pharmaceutical websites
  • Domain names of websites that contain illicit content, such as pornography, illegal drugs, and gambling
Note
  • You are legally responsible for the content that is hosted on your accelerated domain name. ApsaraVideo VOD regularly reviews content served on domain names. If illicit content is detected, ApsaraVideo VOD immediately disables or blocks the domain name. In serious cases, ApsaraVideo VOD may permanently block all domain names that belong to the Alibaba Cloud account.
  • If you add a wildcard domain name such as *.aliyundoc.com to ApsaraVideo VOD and a specific domain name that matches the wildcard domain such as example.aliyundoc.com contains illicit content, ApsaraVideo VOD disables the wildcard domain name *.aliyundoc.com.
  • If your review request is rejected, you can check the reason for rejection on the Domain Names page in the ApsaraVideo VOD console. Then, you can modify the content based on the rejection details and submit the domain name for review again.
