AWS distills its cloud into a local emulator that runs on your PC
Hyperscale meets micro-computing by offering APIs to test your apps
Amazon Web Services (AWS) has introduced an emulator that simulates its cloud environment on a personal computer. This tool, called AWS Emulator, is available on GitHub and functions as a local program that offers AWS API endpoints. It allows users to test their software without connecting to the AWS cloud, enabling development on local machines, development servers, or continuous integration systems.
AWS wrote the emulator in Rust to ensure efficient use of CPU and memory on laptops. The emulator supports AWS service APIs, with over 1,300 APIs currently represented, but it does not replicate all AWS features, such as IAM policies and cross-account or cross-Region behavior. AWS assigns "fidelity scores" to each service, indicating how closely the emulator mirrors AWS behavior.
Developers can use coding agents to evaluate compatibility with the emulator, which identifies AWS operations and resources that the project relies on and assesses their expected behavior. The AWS Emulator is distributed as an RPM or Debian package for Mac and PC users, requiring Docker to run. Once installed, users can point their tools to the local endpoint, allowing existing tests and scripts to function as usual without any changes.
