Two-Tier AWS Architecture using Terraform

Project Description

This project aims to create a robust highily available web application infrastructure using a two-tier architecture on Amazon Web Services (AWS). The architecture comprises a web tier that handles user requests and a database tier for data storage. I leveraged Terraform for Infrastructure as Code (IaC) to provision and manage AWS resources efficiently.

Key Features

• Infrastructure as Code (IaC): Leveraging Terraform for defining and provisioning the entire infrastructure, ensuring consistency and repeatability.
• High Availability: Utilized multiple Availability Zones (AZs), the application is designed for high availability, minimizing downtime in case of failures.
• Security: Implementing security best practices, such as network ACLs, security groups, and encryption, to protect data and resources.
• Database Management: A managed database service Amazon RDS is used to store and manage application data, providing reliability and data durability.
• Load Balancing: Employing Elastic Load Balancers (ELBs) to distribute incoming traffic across multiple web servers, optimizing resource utilization.

Prerequistes

1. Basic knowledge of AWS services and concepts.
   
2. Familiarity with Terraform and infrastructure as code principles.
   
3. An AWS account with appropriate permissions.
   
4. An IDE of your Choice , I would suggest VS Code Editor .
