Full circle
So it is tacitly agreed that remote-Cloud data storage is not perfect. This story indicates that On-prem Cloud is the new way to go.
The difference between On-prem cloud and an On-prem server is that the latter can be maintained by your I.T. department. But because you've shed those jobs and no longer have an I.T. department you are forced to deal with the remotely-based On-prem Cloud team if you need tech support.
So how is that going to work?
Either a remotely-based on-prem Cloud representative will come round and fix your On-prem Cloud appliance (cue memories of calling out British Gas to service your boiler which is under a BG service contract) OR (in most circumstances) the remotely-based Cloud representative can dial-in to your On-prem Cloud appliance and figure out what's wrong. As presumably you will not have access to the gubbins of the On-prem Cloud appliance to mend it yourself.
Hmm, that doesn't sound so nice from a security angle.
Plus, how many times will you hear the excuse - ah, your Router/Firewall is mis-configured, I can't see your On-prem Cloud appliance, or you seem to have an internet problem?
