The risk-based case for cloud storage:
"Pay someone else" to 
redundantly store data.
scale up in response to load.
replace and phase in disks. 
recover from disk failures.
maintain an inventory of replacements.  
versus:
Retain human staff to replace disks. 
Keep your own inventory. 
Make your own backups. 
Create your own data storage policy. 
Etc. 
Why clouds exist: 
The main providers were doing this already!
