AWS Terraform Lab 2 — ASG behind ALB

Overview

Infrastructure built with Terraform in eu-central-1 (Frankfurt):

• VPC + Internet Gateway
• 2 public subnets (multi-AZ)
• Security Groups
• Launch Template (Ubuntu + nginx via user_data)
• Auto Scaling Group (ASG)
• Application Load Balancer (ALB) + Target Group + Listener (HTTP :80)

What I validated

• Opened the ALB DNS and confirmed the custom page: “JovanOps Lab #2 — ASG behind ALB (Terraform)”
• Verified ASG behavior: terminating an instance triggers a replacement (Activity tab shows events).

Run

terraform init
terraform fmt
terraform validate
terraform plan
terraform apply
