With the advent of cloud computing, data storage and scaling has become extremely cheap when compared to the strictly physical server alternative (which require a dedicated facility and substantial fixed/variable costs). Implicitly, we could view cloud computing as having comparatively big ecological advantages over dedicated servers. From this perspective, companies with server/data center needs will have huge incentives to choose cloud computing.
My question is, is the verdict really this simple? Wouldn't some companies be reluctant to use cloud computing for security / conflict of interest reasons? Instead, might they prefer to be the sole custodians of their data? For example, investment banks, hedge funds, ect?
Are there any other compelling reasons that might hold the server / data center industry away from adopting the cloud?
