Turn Based +Google Cloud Service(DataStore)

Hi guys, I have a question don't know if it is possible, Can we integrate Google Cloud Service(dataStore) with photon for a turn based photon game.My agenda is to store player's data(Inventory,cash etc) end of every session that he plays.Yeah I know it ,that it is possible with playfab, but google cloud service are more reliable(i guess).Any solution is appreciated.
Thank you
