## What the models said for it

- "if your organization is deeply invested in a single cloud provider and values deep native integration, the respective native tool (CloudFormation, etc.) is compelling" (MiniMax M2.5, IaC)
- "Choose CloudFormation/CDK, Bicep, or Google Cloud Infrastructure Manager when operating primarily within one cloud." (Perplexity Sonar, IaC)
- "If you are strictly AWS-only with an AWS-native team, CloudFormation/CDK is a reasonable first-party alternative." (Muse Glimmer 30B, IaC)
- "Use CloudFormation if you want zero-installation, native AWS integration, and minimal abstraction overhead." (Qwen 3.7 Flash, IaC)

## And against it

- "Avoid: ... CloudFormation without strict template security" (GLM 4.7 FlashX, IaC)
- "Be cautious when using cloud-specific tools like AWS CloudFormation or Azure ARM templates, as they may limit your ability to migrate or use multi-cloud environments." (Llama 4 Maverick, IaC)
- "Not "avoid," but caution is advised due to verbosity, limited cross-cloud support, and slower feature adoption compared to Terraform." (MiniMax M2.5, IaC)
- "AWS CloudFormation or Azure Bicep are often more performant and up-to-date, but lock you into that provider." (Qwen 3.7 Flash, IaC)
