Does AWS limit bandwidth?

You can limit (or throttle) the upload throughput from the gateway to AWS or the download throughput from your AWS to your gateway. Using bandwidth throttling helps you to control the amount of network bandwidth used by your gateway. By default, an activated gateway has no rate limits on upload or download.

How fast is AWS bandwidth?

Traffic between Amazon EC2 and Amazon S3 can leverage up to 100 Gbps of bandwidth to VPC endpoints and public IPs in the same Region.
