Infrastructure as Code with Terraform: Automate Your VPS Deployments

Why Infrastructure as Code Matters

Manually provisioning servers creates inconsistency — server A has slightly different configuration than server B because a human set each up by hand. Infrastructure as Code (IaC) treats infrastructure configuration as software: version-controlled, peer-reviewed, and repeatable.

Basic Terraform Workflow

# main.tf
terraform {
  required_providers {
    digitalocean = {
      source  = "digitalocean/digitalocean"
      version = "~> 2.0"
    }
  }
}

resource "digitalocean_droplet" "web" {
  image  = "ubuntu-22-04-x64"
  name   = "web-server"
  region = "blr1"
  size   = "s-2vcpu-4gb"
}

State Management

Terraform maintains a state file tracking real infrastructure. Store state remotely in S3-compatible storage for team environments. Never commit state files containing secrets to version control.
