I am a C# / ASP.NET developer so this is my very first exposure to Ruby/Rails. And I have very limited Linux experience.
However, both my development site and production site are working 100% (on the surface) – what part is redis responsible for, and why would the rest of the site work without problems?
More importantly: do you have any suggestions? 
My setup is exactly as instructed & described here: Install Discourse on Windows 10 for development
