Amazon was AWS first customer. I sometimes feel if the AI companies promises of their models replacing all SWE, they would be a top 3 product/service in any number of businesses and not selling shovels to miners.
But they do use their models internally quite a bit. Claude code head talks about how he doesn't write any code himself anymore and just uses agents to do everything. So they are using it themselves.
It wasn't. The retail business took years to move to AWS. They could not even be described as early adopters of AWS.
