Deploy Firely Server on a reverse proxy
For ASP.NET Core 1.0 Microsoft suggested to always use another web server in front of Kestrel for public websites. For ASP.NET Core 2.0, while this is not a hard constraint anymore there are still a series of advantages in doing so:
some scenarios like sharing the same IP and port by multiple applications are not yet supported in Kestrel
helps in limiting the exposed surface area
provides an additional layer of configuration and defense
provides process management for the ASP.NET Core application (ensuring it restarts after it crashes)
in some scenarios a certain web server already integrates very well
helps simplifying load balancing and SSL setup
Hence using a reverse proxy together with the Kestrel server allows us to get benefits from both technologies at once.
A common option on Windows is using IIS: for instructions on how to deploy Firely Server on IIS see Deploy Firely Server on IIS.
