✅メリット
- •Industry standard for IaC
- •Massive provider ecosystem
- •Declarative HCL is purpose-built for infrastructure
- •Excellent state management
- •Huge community and documentation
- •Terraform Cloud for team collaboration
❌デメリット
- •HCL has a learning curve
- •Limited programming constructs in HCL
- •State file management can be tricky
- •BSL license change from HashiCorp
- •Complex modules can be hard to debug
- •Testing infrastructure code is limited
Pulumiとは？
Pulumi is a modern Infrastructure as Code platform that lets you define infrastructure using general-purpose programming languages like TypeScript, Python, Go, and C#.
✅メリット
- •Use real programming languages (TypeScript, Python, Go)
- •Full IDE support with autocomplete and type checking
- •Reuse existing programming skills
- •Better testing with standard testing frameworks
- •Conditional logic and loops are natural
- •Can import Terraform providers
❌デメリット
- •Smaller community than Terraform
- •Fewer examples and documentation
- •Requires programming knowledge
- •Pulumi Cloud for state management (or self-manage)
- •Can over-engineer infrastructure code
- •Less mature ecosystem
