Terraform / Pulumi
Version-controlled infrastructure instead of hand-built servers
What it is
About Terraform / Pulumi
Terraform and Pulumi let teams describe cloud resources — servers, networks, databases, permissions — as code, then apply that code repeatedly and predictably across environments. Terraform uses its own declarative language (HCL), whilst Pulumi lets engineers write infrastructure definitions in general-purpose languages like TypeScript, Python or Go. Both are central to modern DevOps practice, enabling version control, peer review and repeatable deployments instead of manual, error-prone console changes.
What you can do with it
Capabilities
Define cloud infrastructure (compute, networking, storage, IAM) as version-controlled code
Provision identical environments for dev, staging and production
Plan and preview infrastructure changes before applying them
Manage multi-cloud deployments across AWS, Azure and GCP with one workflow
Integrate infrastructure changes into CI/CD pipelines
How to learn it
Learning Resources
Follow HashiCorp Learn / Terraform official tutorials
Work through Pulumi's official Get Started guides and templates
Complete freeCodeCamp and Udemy courses on Terraform for AWS or Azure
Build a small personal project provisioning a VM or S3 bucket end-to-end
Pro Tip
Keep state files remote and locked (Terraform Cloud, S3+DynamoDB, or Pulumi's managed backend) from day one — local state files are the single biggest cause of team-breaking IaC disasters.
