Infrastructure as Code Best Practices

# Infrastructure as Code Best Practices
Treat your infrastructure like software. Version it, test it, and review it.
## Why IaC?
**Reproducibility**
Create identical environments every time. No more "works on my machine."
**Version Control**
Track changes, review them, and roll back when needed.
**Documentation**
Your code IS your documentation. Always up-to-date.
## Tool Choices
**Terraform**
Multi-cloud, declarative, huge ecosystem.
**Pulumi**
Use real programming languages. Great for complex logic.
**CloudFormation**
AWS-native, deeply integrated.
## Best Practices
- Modularize your code
- Use remote state
- Implement CI/CD for infrastructure
- Test with smaller environments first
- Never modify infrastructure manually
Automate everything. Manual changes are technical debt.
