Azure App Service - Is there a limit of free ssl certificates for an app?

Question

I've found several statements online stating that you can have 250-500 custom domains on a single app service (assuming a basic or higher plan). I wonder if anyone knows - can you use a free ssl certificate for each custom domain (no wildcard, just simple www.domain.com)?

I found this:

https://azure.github.io/AppService/2017/07/24/FAQ-SSL-certificates-for-Web-Apps-and-App-Service-Certificates.html#:~:text=App%20Service%20Certificates%20has%20a,types%20the%20limit%20is%203.

Which states that you get 10 certificates - but I could be (and hope I am) reading that wrong or misunderstanding. Do you get 10 certs, or can you get 1 cert for each custom domain (e.g. 200 custom domains = the possibility of 200 free certs)?

Answer 1

Yes,

When you usges free subscriptoins there will be limit for the same. But you can simply raise a rquest to increase the same with azure support or just upgrade your plan from free to Pay As You Go.

What you refer as free ssl certificate is called App Service Managed Certification that is currently in preview. Looking at the doc, this service has no limits yet listed. App Service Certificates have a limit of 10 per subscription that can be increased via a support request to a maximum limit of 200. The managed ones may have the same limits or Microsoft may not have decided on a limit since the service is still in preview but to be sure, I'd suggest that you open a support ticket to clarify this.
