Experience using Blazor server for public internet solution

I plan to use a Blazor Server application for customer access over the Internet.I'm asking about your experiences using Blazor for something like this.

• Do you have such solutions in production use ?
• What about resource usage (how many users can work with which server specs CPU/RAM) ?I read about (for sure depending on the app itself) it should be able to handle thousands of parallel users with 4-8 GB of RAM and few vCPU cores!?
• What is you overall opinion about using Blazor in public apps ?
• Do you use AzureHub for handling SignalR connections ?

Thank you.
