I was explaining one of the aspects of security. Security has multiple facets to it.
Also you mentioned about Internet connection dying, how do you manage when your in premise corporate network fail?

Also in cloud deployment there is option not to deploy the entire data in the cloud, but you can design your app to have data sitting inside your corporate premises and have application hosted in cloud connecting to the in premise data over the service bus.
