Yes all All of the above are is good, until, reality bites back. In come the litigators, the legal authorities, the public cloud provider “Terms of Use” statements. Paid any attention to what has been going on with the “take downs”, cloud service providers going out of business, the organization merges/buyouts? Oh yes very scary stuff. Now the “owners” who thought it was there data have found it's no longer theirs or access has been cut-off. Ouch!

Take control of your own data. Bring it home where it belongs. Use a “private cloud”. Eliminate/minimize the need for a public cloud. If some public cloud access is required then the private cloud becomes a “hybrid cloud” (combination of the two).
