AWS CloudFormation Pros & Cons
- No extra cost beyond the AWS resources it actually provisions, since CloudFormation itself carries no separate service fee
- Deep native integration with every AWS service, often gaining support for new AWS features before third-party tools like Terraform catch up
- Tight integration with other AWS-native tools (IAM, CloudTrail) simplifies permissions and auditing within an AWS-only environment
- Rollback and change set capabilities are deeply integrated with AWS's own infrastructure state tracking
- No separate vendor relationship or tool to manage, since it's a built-in part of the AWS console and ecosystem
- Locked to AWS only, unlike Terraform's multi-cloud support across AWS, Google Cloud, Azure, and other providers
- YAML/JSON templates can become notably verbose for complex infrastructure compared to Terraform's generally more concise HCL syntax
- Less flexible for teams wanting one consistent infrastructure-as-code tool across a multi-cloud or hybrid-cloud environment
- Smaller third-party module ecosystem than Terraform's extensive community-contributed module registry
Pulumi Pros & Cons
- Uses real programming languages, letting teams apply existing language skills directly to infrastructure
- Full IDE support (autocomplete, type checking) works naturally since it's standard code, not a custom DSL
- Existing testing frameworks for the chosen language can test infrastructure code the same way as application code
- Free tier for individual use has no resource limits
- Supports the same range of cloud providers as Terraform through its provider ecosystem
- Smaller community and ecosystem than Terraform's much larger, more established user base
- Requires genuine programming language proficiency, a higher bar than learning a more constrained DSL
- Less standardized configuration patterns across teams compared to Terraform's more uniform HCL syntax
- Smaller library of shared community modules than Terraform's extensive module registry
- Some teams already invested in Terraform face real switching costs to migrate
