If you want to accelerate a specific website, you must use the website as the origin server and create a domain name to accelerate for the website in the Dynamic Route for CDN (DCDN) console. DCDN caches static content from the origin server to cache nodes by using a domain name to accelerate. DCDN retrieves dynamic content from the origin server through dynamic acceleration technologies including smart routing and protocol optimization. In this way, resource access efficiency is enhanced. This topic describes how to add a domain name to accelerate.

Procedure

  1. Log on to the DCDN console.
  2. In the left-side navigation pane, click Domain Names.
  3. On the Domain Names page, click Add Domain Name.
  4. Set Domain Name to Accelerate, Business type, Origin Information, and Acceleration Region.
    Add a domain name
    The following table describes the parameters that are required on the Add Domain Name page.
    Parameter Option Description
    Basic Information
    Domain Name to Accelerate None
    Enter the domain name that you want to add to DCDN, for example, ch.aliyun.com. When you specify this parameter, take note of the following rules:
    • You can use a subdomain name or a wildcard domain name. Example: cdntest.example.com.
    • Wildcard domain names are supported and Chinese domain names are not supported.
    • You cannot add a duplicate domain name. If a DomainAlreadyExist error occurs, submit a ticket.
    • You can add a maximum of 50 domain names to DCDN within your Alibaba Cloud account. If the average daily peak bandwidth values exceed 50 Mbit/s and your workloads are under protection, you can submit a ticket to add more domain names to DCDN.
    • Content that is served from the domain name must comply with the limits of DCDN. For more information, see Limits.
    Note If the specified domain name already exists in Alibaba Cloud CDN or DCDN, the domain name cannot be added.
    Resource Group None Select the resource group where the specified domain name belongs.
    Note If you have not activated the Resource Management service before you add the domain name, the Resource Group parameter is not displayed. To use the resource group feature, log on to the Resource Management console, follow the instructions to enable the resource group feature, and then create a resource group. For more information, see Create a resource group.
    Business Type DCDN You can use this feature to accelerate dynamic content delivery.
    Origin Information
    Type OSS Domain If you select OSS Domain, you can enter the public domain name of an Alibaba Cloud Object Storage Service (OSS) bucket in the Domain Name field, for example, xxx.oss-cn-hangzhou.aliyuncs.com.
    Note To view the public domain name of an OSS bucket, go to the OSS console. You can also select the domain name of an OSS bucket under the current Alibaba Cloud account.
    IP When you select IP as origin server type, you can enter the public IP address of the origin server in the IP field. You can specify the public IP addresses of one or more servers. IP addresses of Alibaba Cloud Elastic Compute Service (ECS) instances are exempt from manual review.
    Site Domain If you select Site Domain, you can manually enter the domain name of your origin server in the domain field. You can specify the domain names of one or more origin servers.
    Note The domain name of the origin server that you specified cannot be the same as the domain name to be accelerated. Otherwise, a DNS resolution loop occurs and requests cannot be redirected to the origin server. For example, if the domain name of your origin server is img.yourdomain.com, you can set the domain name to be accelerated to cdn.yourdomain.com.
    Port None
    Select a port for accessing resources based on your business requirements.
    • Port 80

      Port 80 of the origin server for back-to-origin requests from DCDN.

    • Port 443

      Port 443 of the origin server for back-to-origin requests from DCDN.

    Acceleration Region Mainland China Only If you select Mainland China Only, you must apply for an Internet content provider (ICP) filing with the Ministry of Industry and Information Technology of China. For more information, see ICP filing for domain names.
    Global If you select Global, you must apply for an ICP filing with the Ministry of Industry and Information Technology of China. For more information, see ICP filing for domain names.
    Global (Excluding Mainland China) If you select Global (Excluding Mainland China), no ICP filing is required.
  5. Click Next.
    After the domain name is approved, the domain name is displayed in the Domain Names list. The status is displayed as Running. This indicates that the domain name has been added to DCDN.
    Note
    • You can submit a ticket to speed up the review.
    • If your origin server is an Alibaba Cloud ECS instance or an OSS bucket, the review process takes less time.
    • After you add the domain name to DCDN, DCDN assigns a canonical name (CNAME) to the domain name. The DCDN service takes effect for the domain name only after you create the specific CNAME record for the domain name.
