What is a spot instance in AWS? (32 of 285 technotes for 2015)

  1. Spot Instances allow you to name your own price for Amazon EC2 computing capacity. You simply bid on spare Amazon EC2instances and run them whenever your bid exceeds the current Spot Price, which varies in real-time based on supply and demand.

If using spot instances make sure applications in the server 

  1. start automatically, after the server restarts
  2. saves data often so that there is no loss of data
  3. handles termination gracefully.
