Anyone using IONOS (ex 1&1) VPS hosting to deploy a Webapp?

Hi guys...

Well the tittle says it all...

I have a IONOS VPS and I am trying to deploy an ABMaterial based webapp , but I sometimes don't even know what I am looking at...
Is anyone here that has a VPS hosted by IONOS that can give me a hand?
My VPS has been just sitting there... Now I want to give it some use...

Anyone, Please???
