Advanced. Nope, not at all.
The Blazor Server hosting model has the following limitations:
Higher latency usually exists. Every user interaction involves a network hop.
There's no offline support. If the client connection fails, the app stops working.
Scalability is challenging for apps with many users. The server must manage multiple client connections and handle client state.
An ASP.NET Core server is required to serve the app. Serverless deployment scenarios aren't possible, such as serving the app from a Content Delivery Network (CDN).
LOL scalability? Looks like a poor-man's excuse for a website, not unusual for Hop-ON.
