AWS Production Infrastructure with Terraform

Designed and deployed a highly available, secure, and scalable AWS production environment using Infrastructure as Code (Terraform).

Problem

Many organizations struggle with manually configured cloud infrastructure, leading to inconsistent environments, security misconfigurations, and lack of scalability. The objective was to build a repeatable, production-ready AWS environment using Infrastructure as Code while ensuring high availability and automation.

Solution

Implemented a modular Terraform architecture to provision a custom VPC with public and private subnets, an Application Load Balancer, Auto Scaling Group of EC2 instances, and a Multi-AZ RDS backend.

Architecture Design

• Custom VPC with multi-AZ public and private subnets
• Application Load Balancer (ALB)
• Auto Scaling Group (EC2)
• RDS MySQL Multi-AZ (highly available)
• NAT Gateway for outbound internet access
• IAM Roles and Security Groups

Infrastructure Code Structure

Monitoring & Security

• CloudWatch metrics and alarms
• IAM least-privilege policies
• Encrypted RDS storage
• Security Groups with minimal exposure
• Terraform state stored remotely with locking
