Congratulations! you have reached the end of the workshop. In this workshop, you learned about the need to be flexible with EC2 instance types when using Spot Instances, and how to size your Spark executors to allow for this flexibility. You ran a Spark application solely on Spot Instances using EMR Instance Fleets, you verified the results of the application, and saw the cost savings that you achieved by running the application on Spot Instances.
We hope you found this workshop educational, and that it will help you adopt Spot Instances into your Spark applications running on Amazon EMR, in order to optimize your costs.
If you have any feedback or questions, click the “Feedback / Questions?” link in the left pane to reach out to the authors of the workshop.
