A very good question, here's all that you need to know:
1. Scaling is basically removal of external deposits of tartar or stains on teeth. whitening is basically just that - whitening.
2. Scaling preserves natural tooth shade, it only cleans teeth, in this process due to teeth getting clean, some amount of brightening may occur. Whitening is purely bleaching teeth to enhance natural tooth color and lighten it.
3. Purpose of scaling is preservation of teeth and gums and keeping them healthy, purpose of whitening is cosmetic enhancement.
4. Scaling should be done every year atleast,in all cases, whereas repetetive whitening is not recommended routinely in all cases.
5. Scaling is done by using an ultrasonic instument on all teeth and gums in the mouth, Whitening is done by use of certain chemical agents which bleach tooth on coming in contact with it.
6. Scaling is not harmful, Whitening may cause a slight wear of tooth enamel.
Bottom line : Unless you have completely stained teeth, whitening should be avoided , whereas scaling should be done every year.
Hope it helps
