I agree that privacy concerns may cause those future projections to be a little iffy. All these big cloud players are US based. Even if they maintain data centers in Europe, are European companies comfortable with housing their really important data on Amazon or Google servers? Are they truly compatible with EU data protection laws? Even if they are today will they be tomorrow if a new administration and new terrorist attack makes people forget Snowden and rush headlong into more corporate cooperation with the US government?
