// Terraform on AWS
Infrastructure as Code
AWS infrastructure defined in Terraform: reviewed in pull requests, applied from CI, and reproducible in any environment. Built by a HashiCorp Terraform Associate who has led 6+ production AWS migrations.
No sales layer, no juniors. You meet the engineer before anything begins.
// The case for IaC
Why Infrastructure as Code?
Consistency
Staging and production come from the same code, so a fix that works in one works in the other. No snowflake servers nobody dares to touch.
Speed
A new environment is a plan and an apply, not a two-week ticket. Rebuilding after a mistake takes minutes.
Reliability
Changes get read in a pull request before they reach your account, and drift shows up in CI instead of during an incident.
// Scope
Our IaC Services
Terraform Implementation
Services include
- Versioned, reusable module development
- Remote state in S3 with DynamoDB locking
- AWS account and environment provisioning
- Plan review in CI, so every change is read before it applies
Key features
- Declarative configuration kept in version control
- Plan and apply run in the pipeline, not on a laptop
- Resource dependencies handled by the graph, not by hand
- Drift detection on a schedule
AWS CloudFormation
CloudFormation services
- Template design and development
- Nested stack architecture
- Custom resources where CloudFormation stops short
- Stack drift detection and remediation
AWS integration
- Native coverage of new AWS services
- IAM role-based permissions per stack
- CloudWatch alarms provisioned alongside the resources
- AWS Config rules for compliance checks
Configuration Management
Tools we use
- Ansible playbooks and roles
- Golden AMI builds
- Kubernetes manifests and Helm charts
- Instance bootstrapping through user data and SSM
Capabilities
- Software installation and patching
- Service configuration kept in git, not in someone's shell history
- Security hardening: IAM least privilege, Secrets Manager rotation, WAF
- Repeatable rebuilds instead of manual recovery

Our IaC Implementation Process
Infrastructure Assessment
Go through what is running today, including the parts that were clicked into the console and never written down.
Design and Planning
Decide the module layout, state strategy, and environment structure. Written down and reviewed with you first.
Implementation
Build and test the modules and templates, starting with the resources that change most often.
Migration and Deployment
Import existing resources into state and cut over environment by environment, so nothing is rebuilt blindly.
Handover and Iteration
Your engineers get the walkthrough and the docs. Then we tune for cost and for the changes that come next.
// Next step
Ready to get your infrastructure into code?
The easiest way to start is the AWS Quick Wins Audit, a fixed scope review of your account. It shows what is running, what it costs, and what is worth codifying first. Findings in 2 business days.
