Getting Started with Terraform on AWS

Infrastructure as Code has transformed the way teams manage cloud resources. Terraform lets you define your entire AWS infrastructure in declarative configuration files that can be versioned, reviewed, and shared just like application code.

Why Terraform?

Terraform stands out for its multi-cloud support, declarative syntax, and massive provider ecosystem. The AWS provider alone covers thousands of resources. Your infrastructure becomes code that lives in Git, gets reviewed in pull requests, and deploys through pipelines.

Your First Configuration

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"
    }
  }
}

provider "aws" {
  region = "us-east-1"
}

resource "aws_s3_bucket" "my_site" {
  bucket_prefix = "my-first-site-"
}

The Workflow

1. terraform init — Download providers and initialize the working directory
2. terraform plan — Preview what Terraform will create, modify, or destroy
3. terraform apply — Execute the plan and provision real resources
4. terraform destroy — Tear everything down when you're done

What's Next?

Once you're comfortable with the basics, explore remote state backends for team collaboration, modules for reusable patterns, and CI/CD pipelines for automated deployments. The Terraform ecosystem is deep — there's always more to learn.
