The Terraform configuration files in this project will deploy the following components on AWS:

• VPC with public and private subnets
• Internet Gateway
• Default Route Table
• RDS MySQL Database Instance
• EC2 instance with Ubuntu, Nginx, and MySQL client

Before you begin, ensure you have the following prerequisites:

• Terraform CLI installed (version ~> 1.0)
• AWS account with appropriate credentials
• AWS CLI configured with the desired AWS profile

To deploy the infrastructure stack, follow these steps:

1. Clone the repository:

git clone https://github.com/serajushsalekin/deploy-2-tier-architecture-in-aws-using-terraform.git
cd deploy-2-tier-architecture-in-aws-using-terraform

2. Update the Terraform backend configuration in the provider.tf file. Replace the placeholder values <s3_bucket>, <bucket>, <aws_region>, and <terraform_state_table> with your AWS S3 bucket and DynamoDB table details.

3. Optionally, update the configuration variables in the variables.tf file to customize the deployment according to your requirements.

4. Initialize the Terraform backend and download the required provider plugins:

terraform init

Review and modify the configuration files as needed:

• network.tf: Defines the VPC, subnets, internet gateway, and default route table.
• rds.tf: Specifies the RDS MySQL database instance configuration.
• web-server.tf: Defines the EC2 instance configuration with Ubuntu, Nginx, and MySQL client.

Make sure to update any variables or settings according to your preferences.

To deploy the infrastructure stack, execute the following commands:

terraform plan   # View the execution plan
terraform apply  # Deploy the infrastructure stack

Terraform will show you the changes it intends to make during the "plan" phase. Review the plan carefully before applying it.

After successful execution of terraform apply, Terraform will deploy the infrastructure stack on AWS based on the provided configuration.
