Automated Synthesis of Cloud Emulators

The paper introduces CloudEmu, an automated system that builds cloud emulators by synthesizing code from cloud documentation using a neurosymbolic approach. It combines large language models for understanding documentation with symbolic abstractions to reduce hallucinations and ensure precision, and it employs the real cloud as an oracle for testing and repair. Evaluation shows CloudEmu achieves higher coverage and accuracy than the manually developed LocalStack for AWS and GCP services.
