Comparison

Terraform vs CloudFormation: Which IaC Tool Should You Choose?

Both manage infrastructure as code, the real difference is in portability, state management, and how each fits into a multi-cloud or AWS-only strategy.

Portability

Terraform works across AWS, Azure, GCP, and many other providers with the same workflow. CloudFormation is AWS-only by design.

State management

Terraform maintains a separate state file that has to be stored and managed (typically remotely, with locking). CloudFormation manages state internally as part of the AWS service itself.

Ecosystem and modules

Terraform has a large public registry of community and provider modules. CloudFormation has its own set of AWS-maintained templates and increasingly, higher-level abstractions like the AWS CDK.

Governance

Both ecosystems have policy-as-code and governance tooling that has evolved significantly over time, verify current capabilities directly against each tool’s documentation rather than relying on older comparisons.

Our take

If you’re AWS-only and want tight native integration, CloudFormation is a reasonable default. If you’re multi-cloud, or want the larger ecosystem, Terraform is usually the better fit. See our Terraform Consulting Services page for how we approach implementation either way.
