We just shipped AWS Emulator, which gives coding agents a local copy of AWS to test against.
Early in my career, we built test environments like this by hand, one system at a time. Now, agents are writing code far faster than any team can check it in production. Matt Goldberg, a Senior Principal Engineer on our Developer Tools team, wanted to know whether agents could build and test those environments themselves. He gave @kirodotdev a single prompt, and about 15 minutes later it came back with a first version of an SQS emulator. Turing that into a robust solution took much more work
Here’s what I think this means for engineers today: https://t.co/Nsk9LHS9Mu
In 2004, I picked @SwamiSivasubram as my intern. It was probably one of the best decisions I have made as Amazon's CTO. He learned early that you can only test a system properly in a high-fidelity copy of the environment it will actually run in. AWS Emulator, launched today and written and tested entirely by agents, gives you that kind of environment for more than 200 AWS services.
