## Summary

Amazon launches AWS Emulator, which provides a high-fidelity copy of the environment for more than 200 AWS services for testing systems. Werner Vogels says the emulator was written and tested entirely by agents. He links a guest post by Swami Sivasubramanian on what engineers' jobs become when agents write the code.

## Post

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.
