AWS Emulator and the engineer's job when agents write the code

AWS has launched AWS Emulator, a local testing environment that allows coding agents to test against AWS services, marking a shift in how engineers work as AI agents increasingly write code. The emulator builds on decades of Amazon's distributed systems work, including foundational technologies like Paxos-based consensus protocols and services like DynamoDB and S3, designed to help agents reliably test complex distributed systems before deployment.
