Server dimensions using Genie.jl

Hi there,

my colleagues and I are working on a project where an interactive text book is being built with Julia.
Since we want to host the entire thing on a server to allow others to access and use the notebook we went with Genie.jl .

One of the things I could not find any information on is what kind of server would I need to host a genie webserver which is supposed to be used by roughly 700 users.

I realize that this is pretty abstract but does anyone have experience with offering a genie web server for a few hundred users and what kind of hardware was needed?

Regards,

Why not host it on one of the cloud services (AWS, heroku, etc)?
