terraform modules to build a 2 tier-architecture with route 53

main

THIS SIMPLE PROJECT INVOLVES DEPLOYING A 2-TIER ARCHITECTURE ON AWS USING TERRAFORM MODULES

Architecture Components

The 2-tier architecture consists of:

1. Web App Tier: This tier encompasses the user interface and communication with the application.

2. Database Tier: This tier is responsible for storing and managing information.

Prerequisites

Before getting started, ensure you have the following prerequisites:

• An AWS account
• AWS access key and secret access key
• Terraform version v1.6.4

Setup Instructions

1. Create Root Module Folder

Begin by creating a main.tf file within the root module folder. This file will serve as the main configuration for the root module.

Refer to the configuration file here for a comprehensive example.

2. Define Terraform Variables

In the project directory, create a variables.tf file to define variables that will be utilized throughout the project. Define variables for AWS credentials, VPC CIDR, subnet CIDRs, instance type, AMI ID, and other relevant parameters.

3. Create Terraform Modules

Organize the project by creating separate directories for each Terraform module: vpc, security, alb, database, ec2, and route_53.

Within each module directory, include the following files:

• main.tf for the main configuration
• variables.tf for variable definitions
• output.tf for output configurations

4. Configure Terraform Modules

Reference the child modules in the root module using the module resource. Set the required variables for each child module.

5. Apply Terraform Configuration

Follow these steps to apply the Terraform configuration:

Initialize Terraform:

terraform init

Validate your configuration:

terraform validate

Apply the Terraform configuration:

terraform plan
terraform apply

6. Verify Deployment

Verify the successful deployment of resources on AWS by checking the AWS Management Console.

Now, your 2-tier architecture should be up and running, with the web app tier for the user interface and communication, and the database tier for information storage and management.
