🟢 Goal
Learn how to deploy and manage a production-ready, database-driven web application on AWS using Terraform Infrastructure as Code (IaC), enabling version-controlled, repeatable, and collaborative infrastructure deployments.

🧱 Session Outline

1️⃣ Architecture Overview
Review Project 2 architecture and introduce Infrastructure as Code with Terraform

2️⃣ Terraform Setup
🔹 Project folder structure and file organization
🔹 Configure AWS provider with region and default tags
🔹 Set up S3 backend with DynamoDB state locking

3️⃣ VPC & Networking
🔹 Create VPC with DNS hostnames enabled
🔹 Create Internet Gateway
🔹 Create public and private subnets across 2 AZs
🔹 Configure route tables and associations

4️⃣ NAT Gateway
🔹 Create Elastic IP and NAT Gateway
🔹 Configure private route table for outbound access

5️⃣ Security Groups
🔹 Create security groups for EICE, ALB, App Servers, Data Migration, and RDS
🔹 Configure proper ingress and egress rules

6️⃣ EC2 Instance Connect Endpoint
🔹 Create EICE for secure SSH access to private instances

7️⃣ Secrets Manager
🔹 Reference existing secret using data source
🔹 Parse secret JSON with jsondecode()

8️⃣ RDS Database
🔹 Create DB subnet group
🔹 Deploy MySQL RDS instance with credentials from Secrets Manager

9️⃣ IAM Role
🔹 Create IAM role with EC2 trust policy
🔹 Attach S3 access policy and create instance profile

🔟 ACM & SSL
🔹 Request ACM certificate with DNS validation
🔹 Create Route 53 validation records

1️⃣1️⃣ Application Load Balancer
🔹 Create ALB with target group
🔹 Configure HTTP to HTTPS redirect
🔹 Set up HTTPS listener with ACM certificate

1️⃣2️⃣ Route 53
🔹 Create A record alias pointing to ALB

1️⃣3️⃣ SNS Notifications
🔹 Create SNS topic and email subscription for scaling alerts

1️⃣4️⃣ Auto Scaling Group
🔹 Create launch template with user data script
🔹 Use templatefile() function for variable injection
🔹 Deploy ASG across private subnets
🔹 Attach to ALB target group

1️⃣5️⃣ Data Migration
🔹 Create EC2 instance for database migration
🔹 Configure migration script with templatefile()

1️⃣6️⃣ Deploy & Validate
🔹 Run terraform plan and terraform apply
🔹 Verify application via custom domain

1️⃣7️⃣ Wrap-Up & Q&A
End-to-end review, Terraform best practices, and live Q&A
