You are consulting for a state agency focused on the state lottery. You have been given a task to have 2 million bar codes created as quickly as possible. This will require EC2 instances and an average CPU utilization of 70% for each of them. So you plan to spin up 10 EC2 instances to create the bar codes. You estimate the instances will complete the job from around 11 p.m. to 1 a.m. You don’t want the instances sitting idle for up to 9 hours until the next morning. What can you do to terminate these instances when they are done?
