Can I make my Drobo 5N my personal Cloud Storage?


I’m tired of all this security nonsense and no one taking responsibility for anything… While I do not have anything to hide, I also do not want random people snooping around my financial docs, emails, photos, and other stuff… I want to have it in my house, on my network, with my network security and my permissions that I set on it.
With all said, I have my Drobo 5N sitting here with all my stuff on it. I got a few apps on it. Is there a way, similar to Microsoft’s “OneDrive” or Apple’s iCloud to have my phone & tablet sync to this while we are out and about?
