Deploying a Racket Web Server - racket/racket GitHub Wiki

First: While developing run the racket web-server on your own computer.

Second: When you want to deploy it, the most common solution is to get a vm in the cloud. There are multiple approaches:

Get a vm. Install linux first. Then install racket (including the racket-web server).
Find a host with support for Docker. Use https://github.com/jackfirth/racket-docker as a starting point. Note: You can test your Docker containers on your own computer.

Note that Jesse Alama has written a book on using the Racket web-server: https://gumroad.com/jessealama
