AWS CLI
AWS CLI provides command-line access to AWS service APIs for automation and diagnosis. GenAI engineers use it to inspect model availability, invoke supported operations, and reproduce deployment or permission failures.
Key points
- Profiles and credential providers avoid hard-coded access keys
- JMESPath queries filter JSON output
- CLI commands call service APIs and are governed by the same IAM controls
When to use it
- Reproduce a Bedrock invocation error with a sanitized payload
- Automate an evaluation artifact upload in a build job
Exam tips
- Use the CLI for scripts and diagnostics; an SDK is usually better inside a long-running application
- Avoid shell history leaks and select the intended Region because model support varies
