Pulumi vs Terraform: Decision

Two IaC tools. Pulumi uses real programming languages.

Pulumi

Python/TypeScript/Go for IaC. Loops, abstractions, type safety.

Best for teams with strong programming chops.

HCL DSL. Larger ecosystem; more examples.

Best for traditional ops teams.

Greenfield: Pulumi if team is engineering-heavy. Terraform if team is ops-heavy.

Existing TF: stay; migration is rarely worth it.
