I read the documentation from the official website. but it does not give me a clear picture. Why would need to use AWS Transfer Family since AWS DataSync can also achieve the same result? I notice ...

I want to use Datasync to copy data from a single S3 bucket in one account to a single S3 bucket in another account. I'm following this official AWS Datasync blog: https://aws.amazon.com/blogs/stor...

What is the real world use case difference between AWS data sync and storage gateway, since both allow data transfer from/to on premise data centre and AWS.
