I just discovered that Azure App Services allows you to create one free managed certificate per App Service. For Weather Now, I spent $140 creating two certificates, when really I only cared about the one (for https://www.wx-now.com).
The free App Service managed certificate is a turn-key solution for securing your custom DNS name in App Service. It's a TLS/SSL server certificate that's fully managed by App Service and renewed continuously and automatically in six-month increments, 45 days before expiration, as long as the prerequisites set-up remain the same without any action required from you. All the associated bindings will be updated with the renewed certificate. You create the certificate and bind it to a custom domain, and let App Service do the rest.
The free certificate comes with the following limitations:
- Does not support wildcard certificates.
- Does not support usage as a client certificate by using certificate thumbprint (removal of certificate thumbprint is planned).
- Does not support private DNS.
- Is not exportable.
- Is not supported on App Service Environment (ASE).
- Only supports alphanumeric characters, dashes (-), and periods (.).
That will make a big difference going forward, and saved me $70 for the emergency Inner-Drive.com port going on this week...
