I do like that Azure is integrating Linux.
The datacentre does sound amazing.
However, my top concern is that OGI can not guarantee a connection between our offices and the datacentre. (Understandably not feasible).
If you had iGels / dumb terminals that connected directly to the cloud and your firewall, switch or internet connection has a fault then you could end up being completely unable to do anything until it is resolved.
Personally, I always want the most redundant solution; local servers synchronising with cloud.
