AWS EC2 -- Portfolio Projects
Project 1: HA Web Server with ALB and Auto Scaling
Level: Beginner | Time: 1-2 days | GitHub: aws-ha-webserver
ALB distributing traffic across EC2 in 2 AZs with Auto Scaling at 70% CPU threshold.
hcl
resource "aws_launch_template" "web" {
name_prefix = "web-lt-"
image_id = data.aws_ami.amazon_linux.id
instance_type = "t3.micro"
user_data = base64encode(<<-EOF
#!/bin/bash
yum install -y nginx
systemctl start nginx
echo "<h1>Hello from $(hostname)</h1>" > /usr/share/nginx/html/index.html
EOF
)
}
resource "aws_autoscaling_group" "web" {
min_size = 2
max_size = 10
desired_capacity = 2
vpc_zone_identifier = module.vpc.private_subnets
target_group_arns = [aws_lb_target_group.web.arn]
health_check_type = "ELB"
launch_template {
id = aws_launch_template.web.id
version = "$Latest"
}
}
resource "aws_autoscaling_policy" "cpu" {
name = "cpu-tracking"
autoscaling_group_name = aws_autoscaling_group.web.name
policy_type = "TargetTrackingScaling"
target_tracking_configuration {
predefined_metric_specification {
predefined_metric_type = "ASGAverageCPUUtilization"
}
target_value = 70.0
}
}
Steps: VPC with private subnets, ALB in public, test with stress command, verify auto-scaling
Project 2: Golden AMI Pipeline with EC2 Image Builder
Level: Intermediate | Time: 2 days | GitHub: aws-golden-ami-pipeline
Automated golden AMI with pre-installed packages, hardening, and multi-region distribution.
hcl
resource "aws_imagebuilder_image_recipe" "web" {
name = "web-server-ubuntu22"
version = "1.0.0"
parent_image = "arn:aws:imagebuilder:ap-south-1:aws:image/ubuntu-server-22-lts-x86/x.x.x"
component {
component_arn = aws_imagebuilder_component.hardening.arn
}
}
Steps: Image Builder pipeline, component scripts, weekly schedule, SNS on completion, update ASG
Portfolio Checklist
•[ ] All infrastructure in Terraform (no console clicks)
•[ ] EC2 in private subnets (no direct internet access)
•[ ] Access via Systems Manager Session Manager (no SSH keys)
•[ ] Auto Scaling tested with load test
•[ ] CloudWatch alarms: CPU, disk, unhealthy hosts
