What server, cloud processing, and storage is used for Fornite?

i also want to know some of the best options for indie game developers who are creating Team Based Multiplayer FPS game.

Fortnite is using amazon AWS for a lot of it’s hosting. We have written custom java code that runs in the cloud to handle things like processing and storage. But, there are a variety of other systems that you can use, maybe other developers can share what they use.

Thanks for the answer.
Which OS do you use to run the servers ? Windows or Linux ? If linux, which distribution ?
Thanks.
