A company wants to migrate hundreds of terabytes of on-premises data to AWS, but its network line is thin and online transfer would take months. Which service can migrate the data by loading it onto physical devices and shipping them to AWS?
Selecting a service that migrates large data using physical devices.
AWS DataSync
AWS DataSync is a service that accelerates and automates data transfer over the network between on-premises and AWS.
It is still online transfer, so it does not solve the situation where the line is thin and it would take months, and Snow Family, which ships physical devices, fits, making this incorrect.
AWS Storage Gateway
AWS Storage Gateway is a service for hybrid integration that keeps using cloud storage over standard protocols from on-premises.
Its purpose is day-to-day integration, so the requirement to migrate hundreds of terabytes all at once is met by the physical transfer of Snow Family, and this is incorrect.
AWS Transfer Family
AWS Transfer Family is a service that lets you send and receive files to S3 or EFS over protocols such as SFTP/FTPS.
It is meant to reuse existing file transfer procedures, and the transfer itself is over the network, so it cannot meet the requirement to move hundreds of terabytes over a thin line, making it incorrect.
AWS Snow Family (such as Snowball)
Correct. AWS Snow Family (such as Snowball) is an offline data migration service that writes data onto physical devices, ships them to AWS, and ingests the data. It is effective when the line is thin and online transfer of large data is not practical.
'Large data', 'thin line', and 'ship physical devices' point to AWS Snow Family (Snowball). Online transfer when the line has room is DataSync, and ongoing hybrid integration is Storage Gateway, so use them by line conditions and purpose.
