What is Infrastructure as Code?

Infrastructure as Code (IaC) is a method of managing infrastructure resources like servers, databases, and networks using code. It allows developers to create, configure, and manage infrastructure resources programmatically. With IaC, developers can easily define the desired state of their infrastructure resources and automate the process of creating, updating, and destroying them. It is particularly useful in cloud-based environments where infrastructure resources are dynamic and frequently changing.

What is Terraform?

Terraform is an open-source tool for infrastructure as code that enables developers to easily create and manage infrastructure resources across multiple cloud providers like AWS, Google Cloud, and Microsoft Azure. It allows developers to define the desired state of their infrastructure resources using a high-level language and then automates the process of creating, updating, and destroying them. Terraform provides numerous benefits such as faster deployment of infrastructure resources, reduced manual errors, and improved collaboration between teams.

Getting Started with Terraform

If you’re ready to create and manage your infrastructure like a pro, then you’re in the right place. Terraform is an open-source tool that empowers developers to build and manage infrastructure resources across multiple cloud providers with ease. In this section, we’re going to show you how to get started with Terraform, from installation to using basic commands, so you can start building amazing things in no time!

Installing Terraform

Let’s start by getting Terraform up and running on your local machine. Don’t worry, the installation process is as simple as pie! All you have to do is head over to the Terraform website at and download the appropriate package for your operating system (Windows, macOS, or Linux). 

Once you’ve got the package, extract it to a directory of your choice and add the Terraform binary to your PATH environment variable. That’s it! You’re ready to start your Terraform journey.

Setting up a Terraform Project

Let’s start setting up your first Terraform project! Here are the basic steps to get you up and running in no time:

  • First, create a brand-new directory for your project. This will serve as your project’s home base and allow you to organize your files and resources in one place.
  • Next, create a new file and name it main. tf. This file will contain all the necessary configuration codes to define your infrastructure resources. Think of it as your project’s blueprint, outlining everything you need to bring your project to life.
  • Once you’ve added all the necessary configuration code to the, it’s time to initialize your Terraform project. To do this, simply run the terraform init command. This will set up your project and ensure that all the necessary dependencies are installed.

And there you have it – you’ve successfully set up your first Terraform project! Now you’re ready to dive deeper into the world of infrastructure as code and start building amazing things.

Understanding the Terraform Workflow

This workflow is designed to make managing any type of infrastructure a breeze, and it consists of just three easy steps. Plus, it’s fully customisable to suit your exact implementation needs.

Step 1: Write

The first step of the Terraform workflow is where the magic happens. Here, users create configurations that define or modify the underlying resources. Whether you’re provisioning a simple computer instance in a cloud provider or deploying a multi-cloud Kubernetes cluster, the writing part is a breeze. You can use HasiCorp Configuration Language (HCL), which is the default language for defining resources, or you can use the Cloud Development Kit for Terraform (CDKTF) to define resources using any supported common programming languages like Python, C#, Go, and Typescript.

Step 2: Plan

The second step of the workflow is where Terraform really shines. Terraform will look at the configuration files and create an execution plan that shows users the exact changes that will happen to the underlying infrastructure. This includes any new resources that will be created, any resources that will be modified or deleted, and the exact charges that will be incurred.

Step 3: Apply

The final step of the Terraform workflow is where the magic really happens. Once the plan is satisfactory and the user has confirmed the changes, Terraform will carry out the changes to achieve the desired state in a specific order while respecting all the resource dependencies. Whether or not you have defined dependencies in the configuration, Terraform will automatically identify the resource dependencies of the platform and execute the changes without causing any issues.

To keep track of all the changes to the infrastructure and detect config drifts, Terraform uses the state. It creates a state file at the initial execution and subsequently updates the state file with new changes. This state file can be stored locally or in a remote-backed system like an s3 bucket. Terraform always references this state file to identify the resources it manages and keep track of the changes to the infrastructure.

Basic Terraform Commands

Let’s dive into these commands and explore how they can be used to make magic happen!

  • Terraform init

The “terraform init” command is where the Terraform magic begins! It initializes a new or existing Terraform configuration in a directory and downloads the necessary provider plugins required to manage the resources specified in the configuration. It’s like a wizard’s spell that sets up everything to make your infrastructure dreams come true.

  • Terraform Plan

The “terraform plan” command is your crystal ball. It creates an execution plan that helps you foresee what changes will be made to the infrastructure resources when you apply the configuration. This command helps you see into the future and prepare for what’s to come.

  • Terraform Apply

The “terraform apply” command is like a wand that brings your infrastructure resources to life! It applies the changes specified in the configuration to the infrastructure resources, creating, modifying, or deleting resources to reach the desired state.

  • Terraform Destroy

The “terraform destroy” command is like a reset button. It destroys all resources created by the configuration.

Benefits of Infrastructure as Code with Terraform

  • Code your Infrastructure

Terraform allows you to define your infrastructure resources as code, which means that you can easily version-control, test, and review them just like any other code. This gives you the power to make changes to your infrastructure with confidence, knowing that it can be easily audited and reverted if needed.

  • Multiple Clouds, One Tool

Terraform supports multiple cloud providers such as AWS, Azure, Google Cloud Platform, and more. This means you can manage your infrastructure resources across different providers with a consistent workflow, making it easy to switch between cloud providers or even use them together.

  • Build with Modules

Terraform modules are reusable and shareable components that allow you to organize your infrastructure resources in a modular and scalable way. This helps simplify the management of complex infrastructures, promotes consistency across projects, and reduces the risk of errors.

  • Track and Manage State

Terraform manages the state of your infrastructure resources, making it easy to track changes, identify drift, and roll back changes if necessary. This ensures that your infrastructure is always up-to-date and in the desired state.

  • Platform Agnostics

The majority of IaC tools, such as AWS CloudFormation and Azure Resource templates, are restricted to specific platforms. Nevertheless, Terraform offers a solution by enabling users to employ one tool to handle infrastructure across diverse platforms, along with applications using multiple tools, platforms, and multi-cloud architectures.

  • Reusable Configurations

Terraform promotes the development of reusable configurations, allowing users to use the same configuration for provisioning numerous environments. Moreover, Terraform provides the option to generate reusable components within configuration files by utilizing modules.

  • Join the Community

Terraform has a thriving community of users who share modules, best practices, and examples. This community-driven development model ensures that Terraform is always evolving to meet the needs of its users, and provides a wealth of resources and support for those who are just getting started.

Hands On

we’re going to take a stroll through the creation of a single virtual Private Cloud (VPC) in AWS using Terraform.

Step 0: Prerequisites

Before we begin, let’s make sure we have everything we need. We’ll need to install Terraform, a powerful infrastructure as code tool, and a text editor of your choice.

Step 1: Open Configuration File

Let’s start by creating a new file called in a new folder. This will be our configuration file.

Step 2: Initialize the AWS Provider

Now, let’s configure the AWS provider by adding some nifty code:

provider “aws”


access_key = “Your AWS Access Key”

secret_key = “Your AWS Secret Key”



This code snippet will authenticate you using your AWS IAM account credentials and set some important environment variables, such as “region” to tell AWS to build necessary resources in the “us-east-1” region. It’s important to configure the provider before using it to build resources.

Step 3: Define an aws_vpc Resource

Alright, now we’re ready to define our “aws_vpc” resource, which we’ll call “vpc_name”. Inside the resource block, we’ll specify values for parameters such as cidr_block and instance_tenancy. You can find a complete list of parameters available for every resource in its documentation.

resource “aws_vpc” “vpc_name”





Step 4: Execute Terraform Configuration File

Next up, let’s execute our Terraform configuration file by running some commands:

Step 4: Execute Terraform Configuration File

When we run the command “terraform init”, Terraform will spring into action and install any necessary providers that aren’t already installed. It’ll also initialize our new configuration file.

Next, when we run “terraform plan”, Terraform will show us what changes will be applied in the next step. This is where we can review and make sure we’re happy with what’s about to happen.

Finally, when we run “terraform apply”, Terraform will use your existing credentials to authenticate you with AWS as the user and create the VPC resource. How cool is that?

Step 5: Update

But wait, there’s more! Let’s say we want to add another VPC. No problem! We just need to change our configuration file to add a “count” parameter in the resource block:

resource “aws_vpc” “vpc_name”






Then we save the file and apply it again using the “terraform plan” and “terraform apply” commands. And voila! You’ll see one additional VPC with the CIDR block created. How awesome is that? Terraform really is a magical tool.
