Cloud database and payment processors for adult chat app
 

I've spent the last few months putting together an app similar to whatsapp, with the difference being that you can charge for video or audio calls, charge per message response and send files (videos etc) that the user has to pay to open.

I am making two versions one with the general market and one that allows adult content. I have used open source server software for the video and audio chats so they are encrypted and cannot be taken down. What I am looking for is a place to host these servers that is ok with adult content, a cloud database (or cloud provider that will host a server for this) that is ok with the messages and a recommended payment processor.

What do you all use for your services?

Thanks for you help.
