Welcome to Day 1 of our Terraform Zero to Hero series! If you’re here to learn Infrastructure as Code (IaC) with Terraform and gain practical, hands-on experience, you’re in the right place. This first step will set up your Terraform environment, introduce key concepts, and walk you through deploying your first infrastructure components on multiple cloud platforms. Let’s dive in and get Terraform running smoothly across AWS, Google Cloud Platform, and Microsoft Azure!

What is Terraform and Why Use It?
Before we jump into installation, let’s discuss the basics. Terraform is an open-source tool created by HashiCorp that lets you define, provision, and manage infrastructure with a declarative configuration language. Think of it as a way to “code” your infrastructure setups, enabling you to build and tear down resources quickly and consistently.
Why Infrastructure as Code (IaC)? Using IaC tools like Terraform, teams can:
- Automate infrastructure setups and scaling.
- Maintain consistent environments across development, testing, and production.
- Minimize human error by keeping infrastructure defined in versioned, reusable code.
Terraform’s multi-cloud support also makes it easy to work with various providers, allowing you to create resources on AWS, Google Cloud, Azure, and more using a single tool.

Setting Up Terraform: Step-by-Step Guide
Now, let’s get Terraform installed and configured. This setup process will take you through the basics of getting Terraform onto your machine, verifying the installation, and preparing it to connect with cloud providers.
1. Download and Install Terraform
To begin, download the latest Terraform binary from the official Terraform website. Installation steps will vary depending on your operating system:
- On Windows: Unzip the downloaded file and add the folder to your system’s PATH.
- On macOS/Linux: Unzip and move the binary to a directory in your PATH (e.g.,
/usr/local/bin).
After installation, verify the installation by running:
terraform -vIf installed correctly, this command will display the Terraform version.
2. Setting Up Access to Cloud Providers
Next, let’s configure Terraform to interact with the cloud providers: AWS, Google Cloud Platform (GCP), and Microsoft Azure. Each provider requires authentication, so let’s look at setting up credentials for each:
AWS
- Install the AWS CLI if it’s not already installed.
- Configure your access by running
aws configure3. Enter your AWS Access Key ID and Secret Access Key, along with the default region and output format.
Google Cloud Platform (GCP)
- Install the Google Cloud SDK.
- Authenticate by running:
gcloud auth application-default loginMicrosoft Azure
- Install the Azure CLI.
- Sign in by running:
az loginWith these steps completed, Terraform is now able to communicate with each cloud provider using your credentials.
Creating Your First Infrastructure with Terraform
Let’s now create a simple virtual machine (VM) on each of the three cloud providers. This will demonstrate how easy it is to automate infrastructure provisioning with Terraform across multiple platforms.
Step 1: Write Your First Terraform Configuration
Create a new file called main.tf. This file will contain the Terraform configuration to define a VM instance.
# main.tf
# Specify the provider
provider "aws" {
region = "us-west-1"
}
provider "google" {
project = "your-gcp-project-id"
region = "us-central1"
}
provider "azurerm" {
features {}
location = "West US"
}
# Define a simple EC2 instance for AWS
resource "aws_instance" "my_ec2_instance" {
ami = "ami-0c55b159cbfafe1f0" # Amazon Linux 2 AMI (example)
instance_type = "t2.micro"
}
# Define a VM instance for GCP
resource "google_compute_instance" "my_gcp_instance" {
name = "gcp-instance"
machine_type = "f1-micro"
zone = "us-central1-a"
boot_disk {
initialize_params {
image = "debian-cloud/debian-9"
}
}
network_interface {
network = "default"
access_config {}
}
}
# Define a VM instance for Azure
resource "azurerm_virtual_machine" "my_azure_vm" {
name = "azure-vm"
location = azurerm_resource_group.my_rg.location
resource_group_name = azurerm_resource_group.my_rg.name
vm_size = "Standard_B1s"
storage_os_disk {
name = "myosdisk1"
caching = "ReadWrite"
create_option = "FromImage"
managed_disk_type = "Standard_LRS"
}
os_profile {
computer_name = "myvm"
admin_username = "adminuser"
admin_password = "Password1234!"
}
}Step 2: Initialize Terraform
Navigate to the directory where main.tf is located and initialize the configuration:
terraform initStep 3: Apply the Configuration
Run the following command to create the VM instances as defined:
terraform applyTerraform will display a summary of the changes it’s about to make. Type “yes” to confirm, and Terraform will proceed to create the resources.
Wrapping Up Day 1
By the end of this session, you’ve successfully installed Terraform, connected it with major cloud providers, and created your first VM instances. This foundational setup will serve as the base for more complex and modular Terraform configurations that we’ll build throughout this series.
In the next episodes, we’ll go deeper into Terraform’s capabilities, exploring modules, state management, and advanced configuration techniques that will help you automate and scale cloud infrastructure efficiently.
📌 Stay tuned for Day 2 where we dive into working with multiple providers, regions, variables, and conditions!
