AWS DataSync for Storage Migration
Short answer
A AWS DataSync can migrate data between AWS storage services.
Question
Key Takeaways
The question tests knowledge of AWS migration tools, specifically identifying DataSync as the correct solution for moving data between AWS storage services, distinct from Direct Connect or S3.
AWS DataSync is the service designed to migrate data between AWS storage services and on-premises locations. This page establishes that DataSync automates and accelerates data transfer tasks across these environments.
Common mistake: Learners often confuse AWS DataSync with Amazon S3, which is a storage service itself rather than a migration tool. Others may mistakenly select AWS Direct Connect, which provides network connectivity but does not handle the data movement logic.
Expert Analysis
Why the Answer Is Correct
AWS DataSync is explicitly designed to automate data transfer between on-premises storage and AWS storage services (such as Amazon S3, Amazon EFS, and Amazon FSx). It handles the complexities of data movement, including optimization, scheduling, and security, making it the correct choice for migrating data between AWS storage services.
Why the Other Options Are Wrong
Amazon S3 (Option D) is an object storage service, not a tool for migrating data. AWS Direct Connect (Option B) provides dedicated network connections but does not perform the actual data migration. AWS Lake Formation (Option C) is used for setting up secure data lakes, not for general data migration between storage services.
Community Comment Notes
Community comments confirm that AWS DataSync supports transferring data between AWS storage services. One user noted that DataSync works in three cases, including transferring data between AWS storage services, aligning with the official documentation.
