Hi master/guru/suhu

Can someone help me explain or recommend me.
I was asked by friend to create vb6 application (inventory/accounting) and this part I have no problem
The problem lies when he asked me to make it cloud, so they won't need server to maintain, easy for access, bla bla blah

I want to make the database in accdb format (Access 2007), what should I do to make this cloud ?

Thank you
Very very newbiw for cloud database

Regards
