My organization has briefly entertained the idea of cloud storage, hosting, applications, etc…but we have determined that keeping our information on the physical premises is the way to go about it. Our outfit is at a size where the cost savings (if any) for cloud implementation would not be enough to justify moving away from what we currently have.
Another main concern is that if a cloud company’s security is breached or compromised, that means our data potentially is too. If a company gets in a law suit, or has a poor employee exposing things, their insecurities make us insecure.
Apprehension about cloud security is a major factor in my organizations decision to stay with the physical implementation we have.
