There’s been some discussion about the possible “dangers” or problems of Cloud computing. Some of it, though not all, stems from Richard Stallman’s recent comments about the Cloud initiative. The primary concern is that one may lose control of one’s data, or be at the mercy of (or “locked in” to) a single entity.
To be sure, Mr. Stallman and others make valid points in that if you trust your data to the cloud, where is your control? Where are your options in case of failure? If the entity has a catastrophic error, you could be in a world of hurt.
