## What the models said for it

- "If you are 100% on AWS, AWS CDK allows your developers to write IaC in TypeScript, Python, or Go for $0 in tooling costs." (Gemini 3.5 Flash, IaC)
- "only when the company is firmly AWS-only and values native AWS integration over multi-cloud portability" (Perplexity Sonar, IaC)
- "If you are AWS-only, AWS CloudFormation / AWS SAM / AWS CDK are native and have no IaC tool charge" (Muse Glimmer 30B, IaC)
- "Pulumi/AWS CDK | ✅ Modern choice | Real programming languages, better abstractions" (Kimi K2, IaC)

## And against it

- "Only recommend this if your company is 100% committed to the AWS ecosystem ... this risk might be too high" (Qwen 3.7 Flash, IaC)
- "can be strong choices inside one cloud, but they do not port well across providers" (Perplexity Sonar, IaC)
- "Excellent but AWS-only — limiting if you ever want multi-cloud flexibility" (DeepSeek V4 Flash, IaC)
