Migrating on-premises HDFS data using AWS DataSync
Migrating large datasets from an on-premises HDFS environment to Amazon S3 can be complex, but AWS DataSync simplifies and accelerates this process. In this recipe, you’ll learn how to use AWS DataSync to seamlessly transfer data from Hadoop HDFS to Amazon S3, ensuring a secure and cost-effective migration.
AWS DataSync automates the tasks involved in data transfers, such as managing encryption, handling scripts, optimizing networks, and ensuring data integrity. It supports one-time migrations, ongoing workflows, and automatic replication for disaster recovery, offering transfer speeds up to 10 times faster than open source tools.
AWS DataSync supports the following for HDFS:
- Copying files and folders between Hadoop clusters and AWS storage
- DataSync agents running external to the cluster
- Transferring over internet, Direct Connect, or VPN
- End-to-end data validation
- Incremental transfers, filtering...
