Terraform Project: DevOps Assignment 4

Overview

This Terraform project deploys a simple web application infrastructure on AWS. The architecture includes a VPC with 4 subnets distributed across two Availability Zones. EC2 instances will host a simple web server, with one instance for hosting a web server and the other for deploying a database instance.

Project Structure

The project is organized into multiple files:

• iam.tf: Creates an IAM user and access key.
• outputs.tf: Defines the outputs that display public and private IP addresses of the EC2 instances and IAM user details.
• networking.tf: Defines VPC, subnets, internet gateway, and route table configurations.
• security_groups.tf: Defines the security group configuration.
• keypair.tf: Defines the key pair configuration.
• ec2.tf: Defines the EC2 instances configuration.
