Distributed Denial of Service (DDOS) Protection
Security is still cited as a main reason by your large, stodgy corporations for staying clear of cloud computing. And while the cloud does have its security challenges, there is one key security benefit that cloud computing offers — Distributed Denial of Service (DDOS) protection.
After all, you can try to block, engineer and reroute traffic (difficult) or you can just throw more infrastructure at your attackers (easy) until they get tired of pumping traffic at your web servers. Amazon themselves exemplified this benefit by scaling up infrastructure to disrupt a recent DDOS attack by the group Anonymous.
In a few years I expect large organizations to use the cloud as part of their DDOS strategy, especially as prevalence of this type of attack goes up and the costs of running cloud infrastructure goes down.
