SAA-C03 Question 354
Single answerA company has an on-premises file storage system and wants to migrate a large amount of data to Amazon S3 while minimizing operational overhead. The data transfer should happen securely over the internet with the ability to schedule and automate future incremental transfers. Which service should the company use?
- A
AWS DataSync
- B
AWS Storage Gateway (File Gateway)
- C
Amazon S3 Transfer Acceleration
- D
AWS Snowball
Show answer and explanation
Correct answer: A
Explanation
AWS DataSync is the most suitable service for securely transferring a large amount of data over the internet to Amazon S3. It allows you to schedule and automate incremental transfers, reducing operational overhead. Other options like Storage Gateway and Snowball do not meet the requirements for internet-based or automated data migration.
- A. Correct.
AWS DataSync is designed for large-scale data migrations to AWS storage services like S3. It supports secure, automated, and incremental data transfers, making it ideal for this scenario.
- B. Incorrect.
AWS Storage Gateway (File Gateway) is used to provide on-premises applications with low-latency access to cloud storage, acting as a hybrid solution. It is not designed specifically for large-scale data migrations.
- C. Incorrect.
Amazon S3 Transfer Acceleration is used to optimize uploads to S3 over long distances by leveraging AWS edge locations, but it does not support scheduled or automated transfers and is not ideal for large-scale migrations.
- D. Incorrect.
AWS Snowball is a physical device used for offline data transfer when internet bandwidth is a limitation. Since the scenario specifies using the internet for data transfer, Snowball is not appropriate here.
