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.
Congrats on finding life outside of AWS. Sucks to hear about all the turmoil going on in the US and at Amazon. I had a great time durning my tenure and almost boomoranged back.
