When I was at AWS, retail was not yet running on AWS. Has that changed?

Prime video does use some AWS services, but live and on-demand are two entirely different beasts.

Really? I thought retail was. It's been almost a decade since I worked at prime video but I think everything was running on AWS. (Some things didn't use brazil etc, but I think all the servers etc. were on AWS)

It's a distinction without a difference. All new development is nAWS (native AWS) legacy is mAWS (not sure about the acronym) which is still AWS under the hood and is mostly just a pool of EC2 instances with preconfigured networks. Nothing made in the last five or six years is on maws, and amazon is a micro service shop so things are always being built new. If you joined today there's a good chance you'd join a team without any maws infra

MAWS is “Move to AWS”, the name of the internal campaign to get legacy services into a somewhat-retrofitted AWS environment. It was a single VPC at one point.

I just finished a nearly five year stint at amazon and didn't realize there was pre-maws stuff still around. Never encountered any of it. I was like two months from my yellow badge but, uh, life is really better outside amazon.

many parts of AWS are not on AWS, and there's reasons to have bare metal but it's not as common and aws gives you good access in most cases.
