Infrastructure as Code Best Practices
Versioned, reviewed, and tested infrastructure with repeatable deployment patterns.
Why Infrastructure as Code
Click-ops is the enemy of reliability. If your infrastructure is configured through a web console, it's undocumented, unreproducible, and one misclick away from an outage.
Infrastructure as Code (IaC) means every resource is defined in version-controlled files, reviewed like application code, and deployed through the same pipeline with the same quality gates.
IaC Patterns We Apply
Module Architecture
Reusable, composable modules for common patterns: VPCs, databases, compute clusters. Versioned and tested independently. Teams compose infrastructure from proven building blocks.
PR-Based Reviews
Every infrastructure change goes through a pull request. Plan output reviewed before apply. Blast radius visible before execution. No surprises.
Drift Detection
Scheduled scans compare actual infrastructure state against defined code. Any drift, manual changes, failed applies, external modifications, is flagged and remediated.
State Management
Remote state with locking, encryption, and access controls. State file is treated as sensitive data. Backup and recovery procedures for state loss scenarios.
Terraform vs. Pulumi
We work with both. The choice depends on your team and use case:
- Declarative HCL, purpose-built for infrastructure
- Massive provider ecosystem
- Well-understood state model
- Better for ops-focused teams
- Industry standard, more hiring pool
- Real programming languages (TypeScript, Python, Go)
- Better for complex logic and abstractions
- Native testing with standard test frameworks
- Better for dev-focused teams
- Stronger typing and IDE support
