AWS Website Infrastructure with VPC ec2 ACM Certificate route53 and ALB

Overview

This Terraform configuration sets up a basic infrastructure on AWS, including an ACM (Amazon Certificate Manager) certificate and an internal Application Load Balancer (ALB). The goal is to serve a website with a fully qualified domain name (FQDN) over HTTPS, backed by two private EC2 instances for redundancy.

End results

Terraform Configuration

Prerequisites

1. Terraform: Ensure you have Terraform installed on your local machine. You can download it from Terraform Downloads.

2. AWS Credentials: Configure your AWS credentials using the AWS CLI or by setting the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables.

3. Setting Up Terraform Backend with S3 in the root directory there is a bash script to create s3 bucket and DynamoDb to store the terraform state remoetly

Execution Steps

1. Clone the Repository:

   git clone https://github.com/Iyad87/tech-assignment.git
   cd tech-assignment

Initialize Terraform:

1. change dir to root folder

 cd root
 terraform init

2. Apply the Terraform Configuration:

terraform apply

During the terraform apply step, Terraform will prompt you to confirm the changes. If you're sure, type yes and press Enter. Access the Website: After Terraform applies the configuration, the ALB DNS name will be output as website_url. Visit this URL in your browser to see the website. Clean Up (Optional): To destroy the infrastructure and associated resources:

terraform destroy

Type yes when prompted to confirm. Customization Domain Name: Sub_Domain: Update the domain_name in main.tf to your desired domain. Region and Availability Zones: Adjust the region and azs variables in main.tf based on your preferred AWS region and availability zones.

ACM Certificate:

If you have a specific ACM certificate ARN, replace the default value in terraform.tfvars. Output The ALB DNS name will be output as website_url. Visit this URL to access the website. Important Notes

AWS Credentials:

Ensure your AWS credentials have sufficient permissions to create and manage the required resources. ACM Certificate Validation: ACM certificates may require DNS validation. Ensure you have control over the DNS records for the specified domain.

Security Considerations:

This configuration sets up an internal ALB for enhanced security. Review and adjust security settings based on your requirements.
