Security's on Cloud 9... or is it Cloud 85?

I was writing a story on Iveda teaming with mobiDEOS the other day, and I noticed in my interviewing the terms "cloud computing" and "in the cloud" and "cloud technology" were being dropped a lot. I had to be honest with myself and admit, while I kind of got the basic idea of cloud computing, I wasn't exactly sure what it meant, how it worked, and what kind of effect its advent would have on the security industry. The cloud, and cloud computing has been mentioned in a couple of SSN stories recently, and I felt it was time I educated myself. I found a well done article on the emerging phenomenon at Datamation. It gets into just what cloud computing is, how the emerging cloud is being shaped, and what ramifications it will have on numerous industries, including security. There's also a list of 85 cloud computing vendors battling it out for market share right now. Interesting stuff, and useful info with implications for both the physical and data security industries. Enjoy.
