CloudFormation
Infrastructure as Code for AWS resource automation and management
What it does well
- Native AWS integration with support for 500+ resource types
- Change sets allow safe preview of infrastructure changes before applying
- Stack policies, drift detection, and change tracking for governance
- Cost-free service with pay-only-for-resources model
- Multi-region and cross-account deployment capabilities
Where it falls short
- Steep learning curve with complex, verbose template syntax
- Slower deployment times compared to some alternatives
- Limited error messages and debugging capabilities
- Lock-in to AWS ecosystem with limited multi-cloud support
