One of the common complaint about using AWS is the egress fees, which can be quite significant if a company wants to transfer lots of data out of the cloud. I happen to chance upon this announcement which I missed last year, that talks about a way for customers to perform data transfer out (DTO) for free.
The caveat is that this offer is only for customers who are migrating away from AWS, and you will need to contact support to make a request – although it says AWS doesn’t require customers to close their accounts. Also, it appears that the “free exit” window is time-limited. Meaning once you get an approval, you should quickly migrate your data before the free DTO window is over.
We believe this choice must include the one to migrate your data to another cloud provider or on-premises. That’s why, starting today, we’re waiving data transfer out to the internet (DTO) charges when you want to move outside of AWS.
