Description
In this lab, you will learn how EC2 spot instances can be used in AWS. You will see that spot instances can be used in much the same way as regular, on-demand instances except with a different pricing model built around them allowing you to save a substantial amount. You can set a maximum price that you are willing to pay for an instance, and if the spot market price rises to your maximum, your instance is subject to termination. Despite this complication, you will see that there are ways to manage this situation.
