Own DB servers hosting by self

Hello, I've built a chat app with CloudDB, and it works very well across all devices. Now I want to have my own database to manage everything myself. CloudDB is hosted by MitAppInventor. Does anyone have an idea or a solution for how I can host a CloudDB server myself, or how their server is hosted so I can replicate it?

Thank you very much.
