Infrastructure as Code
Version-controlled, reproducible infrastructure
Infrastructure as Code (IaC) defines your entire infrastructure in code files, making it reproducible, version-controlled, and auditable.
Infrastructure as Code is included in S and M plans only.
Supported tools#
| Tool | Use Case |
|---|---|
| Terraform | Multi-cloud infrastructure provisioning |
| Pulumi | Infrastructure in your preferred programming language |
| Ansible | Configuration management and automation |
| Helm | Kubernetes application packaging |
Benefits#
Reproducibility#
- Recreate entire environments from code
- Consistent dev/staging/production environments
- Disaster recovery from source control
Version control#
- Track all infrastructure changes
- Review changes before applying
- Rollback to previous states
- Audit trail of modifications
Automation#
- Automated provisioning
- Self-service infrastructure
- CI/CD integration
- Drift detection
What we implement#
Infrastructure provisioning#
- Cloud resources (compute, storage, networking)
- Kubernetes clusters
- Databases and caches
- Load balancers and CDNs
- DNS and certificates
Configuration management#
- Server configuration
- Application configuration
- Secret management integration
- Environment variables
IaC practices#
| Practice | Description |
|---|---|
| Modular design | Reusable infrastructure modules |
| Environment parity | Identical configs across environments |
| State management | Secure remote state storage |
| Drift detection | Alert on manual changes |
| Change validation | Plan review before apply |
| Automated testing | Infrastructure test suites |
Workflow#
- Define — Write infrastructure as code
- Plan — Preview changes before applying
- Review — Code review for infrastructure changes
- Apply — Automated deployment via CI/CD
- Monitor — Detect and alert on drift
