Cloud Infrastructure Setup For Web

Sure, let's start designing the infrastructure for the e-commerce platform on AWS. We'll use Terraform to provision the necessary resources. ### Phase 1: Networking and Load Balancing ```hcl # main.tf provider "aws" { region = "us-east-1" # Change this to your desired region } # Create a VPC resource "aws_vpc" "ecommerce_vpc" { cidr_block = "10.0.0.0/16" enable_dns_support = true enable_dns_hostnames = true tags = { Name = "ecommerce-vpc" } } # Create a public subnet resource "aws_subnet" "public_subnet" { vpc_id = aws_vpc.ecommerce_vpc.id cidr_block = "10.0.1.0/24" availability_zone = "us-east-1a" # Change this to an available zone in your region map_public_ip_on_launch = true tags = { Name = "public-subnet" } } # Create an Application Load Balancer resource "aws_lb" "ecommerce_lb" { name = "ecommerce-lb" internal = false load_balancer_type = "application" security_groups = [aws_security_group.lb_sg.id] subnets = [aws_subnet.public_subnet.id] } # Create a security group for the load balancer resource "aws_security_group" "lb_sg" { vpc_id = aws_vpc.ecommerce_vpc.id // Define your security group rules as needed } # Output the DNS name of the Load Balancer output "lb_dns_name" { value = aws_lb.ecommerce_lb.dns_name } ``` Run `terraform init` and `terraform apply` to create the networking and load balancing resources. After this step, prompt me with 'Continue' to proceed to the next phase. ### Phase 2: Database Setup (Amazon RDS) ```hcl # database.tf # Create an RDS instance for the database resource "aws_db_instance" "ecommerce_db" { identifier = "ecommerce-db" allocated_storage = 20 storage_type = "gp2" engine = "mysql" engine_version = "5.7" instance_class = "db.t2.micro" name = "ecommerce_db" username = "admin" # Change this to your preferred username password = "password" # Change this to your preferred password publicly_accessible = false multi_az = true vpc_security_group_ids = [aws_security_group.db_sg.id] } # Create a security group for the database resource "aws_security_group" "db_sg" { vpc_id = aws_vpc.ecommerce_vpc.id // Define your security group rules as needed for the database } # Output the endpoint of the RDS instance output "db_endpoint" { value = aws_db_instance.ecommerce_db.endpoint } ``` Run `terraform apply` again to create the RDS instance for the database. After this step, prompt me with 'Continue' to proceed to the final phase. ### Phase 3: Auto Scaling Group for Application Servers ```hcl # autoscaling.tf # Create an IAM role for EC2 instances in the Auto Scaling Group resource "aws_iam_role" "ec2_role" { name = "ec2_role" assume_role_policy = <<EOF { "Version": "2012-10-17", "Statement": [ { "Action": "sts:AssumeRole", "Effect": "allow", "Principal": { "Service": "ec2.amazonaws.com" } } ] } EOF } # Attach an IAM policy to the role (you may need to customize this policy) resource "aws_iam_instance_profile" "ec2_instance_profile" { name = "ec2_instance_profile" role = aws_iam_role.ec2_role.name } # Launch Configuration for the Auto Scaling Group resource "aws_launch_configuration" "ecommerce_launch_config" { name = "ecommerce-launch-config" image_id = "ami-xxxxxxxxxxxxxxxx" # Replace with a valid AMI for your application instance_type = "t2.micro" security_groups = [aws_security_group.app_sg.id] key_name = "your-key-pair" # Replace with your key pair iam_instance_profile = aws_iam_instance_profile.ec2_instance_profile.name lifecycle { create_before_destroy = true } } # Auto Scaling Group resource "aws_autoscaling_group" "ecommerce_autoscaling_group" { desired_capacity = 2 max_size = 5 min_size = 2 vpc_zone_identifier = [aws_subnet.public_subnet.id] launch_configuration = aws_launch_configuration.ecommerce_launch_config.id health_check_type = "EC2" health_check_grace_period = 300 # Adjust as needed tag { key = "Name" value = "ecommerce-instance" propagate_at_launch = true } } # Output the Auto Scaling Group name output "asg_name" { value = aws_autoscaling_group.ecommerce_autoscaling_group.name } ``` Run `terraform apply` once more to create the Auto Scaling Group for your application servers. This will launch EC2 instances that automatically adjust based on demand. After this step, you'll have a scalable and dynamic infrastructure for your e-commerce platform on AWS. Remember to replace placeholder values in the code (such as AMI ID, key pair, etc.) with your actual configurations. Feel free to ask if you have any questions or if there's anything else you'd like to add!
