🚀 Overview:
The building of the infrastructure and deploy of a web page on AWS using Terraform aims to create a scalable and resilient infrastructure that leverages the power of Amazon Web Services (AWS) cloud platform. This project utilizes Terraform, an Infrastructure as Code (IaC) tool, to provision and manage the infrastructure components, enabling automation, repeatability, and scalability. This project demonstrates how to provision, deploy and destroy infrastructure on AWS using Terraform and automate the deployment with bash Scripting. A deployment script (deploy.sh) and a destroy script (destroy.sh) are use for the automation process. It’s a hands-on DevOps project showing Infrastructure as Code (IaC) and automation.
🔧 Problem Statement
Terraform is an IaC software tool that provides a consistent command line interface (CLI) workflow to manage hundreds of cloud services. Terraform codifies cloud APIs into declarative configuration files. In this specific case you need to create foundation Networking(VPC, Subnets, route table, IGW, NAT Gateway...), Terraform will automatically use the configuration files to provide the infrastructure resources where we can run application needed. Terraform will use his deployment to provide all AWS needed elements avoiding us to use the console and it will automate the setup, ensuring consistency and reducing human error. The bash scripting and the other hands will facilitate the deploy by simply automating the process.
💽 Techonology Stack
The architecture consists of the following three tiers:
AWS VPC: AWS VPC
Subnets: AWS Subnets
Route table: AWS route table
NACL: AWS NACL
Internet Gateway: AWS IGW
Elastic Load Balancer: AWS ELB

🌟 Project Requirements
Before you get started, make sure you have the following prerequisites in place:
Terraform installed on your local machine.
AWS IAM credentials configured in your text editor. In this case we will use VSCODE.
Git installed on your local machine and Github account set up Github
Git for cloning the repository.
You must also know Terraform workflow
📋 Table of Contents
I - Terraform Configuration files
Step 1: Provider Configuration
Step 2: Variables Configuration
Step 3: Main Configuration
Step 4: Output Configuration
Step 5: User-data
II - Scripting files
Step 6: Deploy file
Step 7: Destroy file
III - Instructions of Deployment
Step 8: Clone Repository
Step 9: Run Deployment
Step 10: Destroy Infrastructure
You need to write different files generating resources
Step 1: Provider Configuration
Here we declare our cloud provider and we specify the region where we will be launching resources
Step 2: Variables Configuration
This is where we declare all variables and their value. It includes
We have
Step 3: Main Configuration
This is where you create the basement, foundation and networking where all the resources will be launch. It includes VPC, Subnets, IGW, Route tables, Security groups, EC2 instances, Targets group and Elastic load balancer
Step 4: Output Configuration
Know as Output Value : it is a convenient way to get useful information about your infrastructure printed on the CLI. It is showing the DNS name of the load balancer and public IP of the instances.
Step 5: User-data
user data is a script or custom data that you provide to an EC2 instance to be executed automatically on its first launch. It's used to automate the initial setup of an instance, such as installing software, configuring settings, or running commands needed to make the instance ready for use. In our case the user data will update the server, install Nginx and copy the index.html file to the correspondant folder.
✨Bash Scripting files
You need to write different bash script files generating and destroying resources. The file will contains all step by step meaning all terraform command for the execution of the process.
Step 6: Deploy file
Here we declare the initialization of the folder, the validation of the configuration, the plan of resources to be create and apply of the execution where we will be launching resources.
Step 7: Destroy file
This is where we declare the terraform command to destroy all the resources created.
💼 Instructions of Deployment
Follow these steps to deploy the architecture:
Step 8: Clone Repository:
Clone the repository in your local machine using the command "git clone" then enter the folder
git clone https://github.com/Joebaho/Flipkart-Deploy.git
cd Flipkart-Deploy
Step 9: Run Deployment
Initialize the folder containing configuration files that were clone to Terraform and apply the configuration by typing the following command
chmod +x deploy.sh
./deploy.sh
The process will execute all terraform command and display the following steps. You must see this image
Terraform init: Initialize the folder
Terraform fmt & validate: Check for any syntax error and valid the status of the configuration files
Terraform plan: confirm the numbers of resources that will be create
Terraform apply: confirm all resources created
Terraform output: show all the output information to be use by user.
After copy the ELB dns name in the output section you can go paste that in a new window on the browser and the web page will display.
Step 10: Destroy infrastructure
After you are done with the infrastructure and you are ready to destroy you can run the command. First you make the file executable then you apply execution.
chmod +x destroy.sh
./destroy.sh
After typing or pasting the command you will get images
You will need to confirm the destruction of the deployment. Then all the 16 resources created before will be destroyed.
📌 Learning Outcomes
