Security is unsurprisingly a very hot topic in The Cloud Computing - should you be doing it? debate.
On one side we have the my-hardware-is-my-castle group of people, who find it deeply unnatural to even think of delegating your compute environment to some abstract entity that assures you that you own the capacity of X number of machines at any given time, but which you cannot see or touch. Not to mention the question of your data.
On the other, we find the people who do not really mind the mystical concept of the cloud at all. Their main interest is in having instant access to somewhat unlimited amount of compute resources at a reasonable cost. Unfortunately, they might occasionally concentrate too much on getting a job done quickly, ignoring some valid, healthy concerns that the former group puts forward.
Then there is the middle ground - those of us who recognize the sacrifices one has to accept when moving to the cloud as well as the various solutions...
