What are the frameworks , backends c-sharpcorner com is build up?

I know c-sharpcorner com uses .NET but what specific frameworks it uses like I think it uses Web Forms but I may be wrong?

Question are:

1. .NET framework?

2. Blazor or MVC or Razor Pages.

3. Which database like MongoDB or SQL Server or MySQL.

4. Where they host Azure, AWS, Google Cloud.

5. Do they use Kubernetes or Docker?

6. Entity Framwork Core/ Dapper or ADO.NET?

7. CDN like Cloudflare or other?

8. Bootstrap or just there own custom CSS?

9. Web Server - IIS, Nginx or Apache.

Would like to know because they handle lot of traffic in an excellent way and so I will be interesting to know their tech usages.

Thank you
