Infrastructure as Code
Infrastructure as code means your cloud environment is defined in text files, version-controlled in Git, reviewed like application code, and applied automatically. The alternative — infrastructure that exists only in a web console — cannot be reproduced reliably, cannot be audited, and cannot be recovered after an incident without guesswork.
IaC tools we work with
Infrastructure as Code
Terraform
HCL-based infrastructure definitions for AWS, multi-cloud, and SaaS providers. Modules, remote state, and workspace management.
View service →Infrastructure as Code
Pulumi
Infrastructure defined in TypeScript, Python, or Go. Real programming languages for infrastructure with loops, conditionals, and abstractions.
View service →The console is not documentation
When infrastructure is created through a web console, the intent behind every configuration choice disappears the moment the person who made it leaves the team. Infrastructure as code makes the configuration explicit, reviewable, and understandable to the next person who has to change or debug it.
Plan before apply
Both Terraform and Pulumi support a plan or preview step that shows exactly what changes will be made before they are applied. We enforce this as a required step in the pipeline so that no infrastructure change happens without a human reviewing the diff first.
Modules and reuse
A Terraform module or a Pulumi component is the IaC equivalent of a function — a reusable unit that encapsulates a common pattern. We write modules for recurring infrastructure patterns so that the same configuration is not duplicated across multiple environments or services.
State is a first-class concern
Terraform and Pulumi both maintain a state file that maps declared resources to real cloud resources. This state file must be stored remotely, locked during operations, and never edited manually. We set up remote state with S3 and DynamoDB locking (or the equivalent) before writing the first resource definition.
Common questions
Ready to manage infrastructure as code?
If your infrastructure is managed manually or you want to migrate existing cloud resources into Terraform or Pulumi, reach out and we will assess the scope.
