- If you're lucky enough for your business to be around for the long haul, odds are that it'll ultimately be hit with a lawsuit or a breach in some capacity, some way, that will involve a cloud provider. And...
- Your cloud providers won't be prepared to help you out. At least in the foreseeable future.
I can't stress this enough: unless you want to appear foolish, think through the security, legal, and business aspects of cloud computing before you fall for the marketing hype and jump on the bandwagon.
I've written pieces with more insight and prescriptive cloud advice here. Take it slow and good luck.
