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.
Common questions
Neither is universally better, Terraform is cloud-agnostic and has a larger ecosystem; CloudFormation is AWS-native with no separate state file to manage.
Some teams do, though mixing tools adds complexity, most teams are better served picking one.
Yes, that's one of its main advantages, the same tool and workflow across AWS, Azure, and GCP.
