Creating a CDN with a pre-existing Web Application for China

Question

Hello.

We have deployed our application on Azure App Services for a few months.

Recently, our application was not accessible in China and we think that it is because we have not activated China CDN for our deployment. We have tried to setup CDN follow the link, however when we try to do step 2, of first going to the Azure Management Portal, we get an error saying that "ouinno.com isn't in our system. Make sure you typed it correctly.".

Currently, the email that we are using has the domain ouinno.com so we do not understand what the issue is.

Thank you very much

Hi Philip Kong,

• The error message you are seeing - "Ouinno.com is not in our system" - not referring to your application domain or deployment; This is likely to mention the fact that your email domain (OUINNO.com) is not associated with the correct Azure Active Directory (AAD) tenant or azure membership in the China region.
• Azure is operated differently in China due to regulatory requirements. Microsoft Azure services in China are powered by 21vianet, which is completely different from the global Azure. This means:
• Azure is a separate portal in China: https://portal.azure.cn/

Accounts, services and membership should be specially installed within the Azure operated by 21vianet.

• Unless you create a separate account in Azure China, your global azure credentials (like your ouinno.com email) do not function automatically.
• To make your app accessible in China using CDN, here are steps to follow: Check if your target audiences are in the mainland China. If yes, it is best to directly deploy its application to China regions (such as Eastern China or North China) for optimal performance.
• Create an Azure China account (if you are not already): Use this official link: https://www.azure.cn/en-us/free/ This will be a completely different atmosphere from your current Azure Global Account.
• Azure deploys your app for China app services: Reference: https://learn.microsoft.com/en-us/azure/china/resources-developer-guide
  By exporting/importing settings or codebase, you may need to migrate your app from global azure to China.
• Azure Use China CDN: Reference: Azure CDN in China Azure CDN setup in China should be done through China portal (https://portal.azure.cn), and endpoints should be combined with Azure China resources.
• Be sure to configure DNS records (eg CNAME) to indicate your China CDN and points once set.
• Alternative Options: If Azure is not possible to migrate in China, you can also detect licensed third-party CDN providers in China, such as Cloudflare with China Network or Alibaba Cloud CDN, which are integrated with ICP-licensed services. https://learn.microsoft.com/en-us/azure/china/
