Amazon EC2 Spot Instances let you run flexible, fault-tolerant, or stateless applications in the AWS Cloud at up to a 90% discount from On-Demand prices. Spot instances are regular EC2 capacity that can be reclaimed by AWS with a 2-minute notification called the Interruption Notification. Applications that are able to gracefully handle this notification and respond by check pointing or draining work can leverage Spot for deeply discounted compute resources! In addition to Interruption Notifications, Rebalance Recommendation Events are sent to spot instances that are at higher risk of being interrupted. Handling Rebalance Recommendations can potentially give your application even more time to gracefully shutdown than the 2 minutes an Interruption Notification would give you. It can be challenging to test your application's handling of Spot Interruption Notifications and Rebalance Recommendations.
