Amazon makes their money back with AWS integration. If you make a multiplayer game or simply any kind of game that’s connected to the internet, you have the choice of either rolling your own server solution or use Amazon’s services. AWS is better for indies because the servers are maintained by Amazon and you only pay for what you use. Maintaining and hosting your own servers can get really expensive and thus unsuitable for smaller developers with very little money. AWS can get expensive as well, but only if you get big.
