Hi Team,
I have an Azure Website which I am selling as a SAAS. My problem is that currently Azure App Service has a hard limit of maximum 500 sub-domains that I can create under a single App Service. All my 500 sub domains points to the same App Service and based on the sub-domain name, I am dynamically changing the UI.
My problem is that because of this hard limit of 500, I am not able to scale my application further and as a temporary workaround I had to create another instance of App Service with duplicate code although this is a wrong approach.
Hence I was wondering if your team can assist in this issue or increase my sub domain limit to 1500 so that I can sell my SAAS model better.
Also I found this article but not sure if this will work
https://stackoverflow.com/questions/60820639/azure-app-service-workaround-500-custom-domain-limit
I believe 500 is a hard limit but I will double internally with the engineer team and get back to you.
Thanks,
Grace
Hello Grace,
Can you please check of an alternate solution to this problem as well. Like if i want to have more sub domains all pointing to the same Azure App service. Also we are planning to use azure Traffic manager but i dint know if there us a hard limit on routing based on sub domains.
Hi All,
Can you please update on this.
@Red Matter Architect apologies for the delay in response. still waiting to hear back from the team. I should have an update for you hopefully by tomorrow. thanks for your patience!

Hi @Red Matter Architect , Thank you so much for your patience. The engineering confirmed 500 is a hard limit.
We won’t be able to increase the 500 limit of their app. Using Traffic Manager is the best route for your scenario.
Please let us know if you have further questions.
Best,
Grace
Hey @Grmacjon-MSFT , Thanks for your response and from your reply as I understand, we can use Traffic Manager to have more than 500 sub-domains and all pointing to the same Azure App Service but different endpoints. Can you please confirm if there is any hard limit on Traffic Manager configured rules too like how many can I create inside Traffic Manager
Hello @Red Matter Architect ,
II don't believe there should be a limit because it’s just DNS records you’re configuring to point to Traffic Manager. Also, there’s wildcard domains that we support on Azure App Service. You can learn more about it in this Azure doc.
