Cloud Computing: Just Pie in the Sky or a Practical Tool for Publishers?
From a physical security perspective, providers house their operations in Fortune 100 class data centers with 24/7, 365-days-a-year staffing on-site, state-of-the-art server farms with redundant capability, access control, surveillance, multiple telecom lines and carriers, backup power generation and UPS, smoke detection and fire control, along with network redundancy.
Cloud-based providers will exist solely for the purpose of providing these utility services, much like the electric company. The Googles, Amazons, Salesforce.coms and NetSuites wouldn't be around very long if they couldn't provide these services reliably and affordably on behalf of thousands of customers.
Very few businesses, and I suspect this includes magazine publishers, can afford to continuously keep up with the investment and competence required to advance in the areas of world-class IT security and reliability when it comes to the care and feeding of their systems.
