Summary

Over the course of this chapter, we have learned about recommendations around choosing between transient and persistent clusters, how you can right-size your cluster with different EC2 instance types, and EC2 pricing models. We have also provided best practices around EMR cluster configurations that included cluster scaling, high availability, monitoring, tagging, catalog management, persistent storage, and security best practices.

Then, later in the chapter, we covered cost-optimization techniques that included recommendations around compute and storage, and also covered different tools AWS offers, such as AWS Cost Explorer, AWS Trusted Advisor, and cost allocation tags to monitor and control your costs with alarm notifications with AWS Budgets.

That concludes this chapter and, with it, we have reached the end of the book! Hopefully, this book has helped you to get deep knowledge of EMR's features, usage, integration with other AWS services, on-premise migration...
