Pulumi: The Next Gen IaC

Terraform uses a custom language (HCL). Pulumi allows you to use Real Programming Languages like TypeScript, Python, or Go to define your infrastructure. This is the ultimate "Developer Experience."

1. Why use a real language?

• Loops and Conditionals: Use standard `for` loops and `if` statements instead of complex HCL syntax.
• Strong Typing: Catch infrastructure errors in your IDE with TypeScript before you even run the code.
• Existing Libraries: Use NPM or PyPI packages directly in your infrastructure code.

2. Perfect for Modern Devs

Pulumi feels like writing a standard app. It uses the same backend state model as Terraform but provides a much more powerful and familiar interface for full-stack developers.

4. Interview Mastery

Q: "Does Pulumi replace the Cloud Development Kit (CDK)?"

Architect Answer: "Pulumi is similar to AWS CDK or Azure Bicep, but it is **Cross-Cloud**. AWS CDK only works for AWS. Pulumi can manage AWS, Azure, GCP, and Kubernetes in a single script. For an architect building a **Multi-Cloud** strategy, Pulumi is the far more flexible choice."
