Summary
Over the course of this chapter, we have looked at an overview of different migration strategies you can follow while migrating your on-premises Hadoop workloads to AWS, and how you can migrate data, metadata, and ETL jobs. We then covered a few testing and validation strategies you can follow to check the quality of your data, and also discussed some of the best practices you can follow during the migration process.
That concludes this chapter! Hopefully, this helped you get an idea of how you can plan your migration and some of the aspects you should be considering. In the next chapter, we will examine some of the best practices for EMR, along with how you can optimize costs while integrating your ETL flows.
