There are 3 types
Spot instances – Spot Instances allow you to name your own price for Amazon EC2 computing capacity. You simply bid on spare Amazon EC2 instances and run them whenever your bid exceeds the current Spot Price, which varies in real-time based on supply and demand.

Reserved instances – Long Term commitment, this option can save you up to 60% over On-Demand rates.

Spot can be valuable when you want to use/pay only if the price is good for you.
