None. The only difference is where the data resides (so probably the IP addresses and DNS names of the servers are different).
Don't believe the hype. "Cloud" is not magic, it's just remote hosting.

actually I found the question in a review: What is the difference between traditional data warehouse security and its security in the cloud?
