resource "aws_vpc" "main" {
  cidr_block = "10.0.0.0/16"
  
  tags = {
    Name = "Main VPC"
  }
}

# Create a subnet
resource "aws_subnet" "main" {
  vpc_id     = aws_vpc.main.id
  cidr_block = "10.0.1.0/24"

  tags = {
    Name = "Main Subnet"
  }
}

# Create a security group
resource "aws_security_group" "allow_web" {
  name        = "allow_web_traffic"
  description = "Allow inbound web traffic"
  vpc_id      = aws_vpc.main.id

  ingress {
    description = "HTTP from VPC"
    from_port   = 80
    to_port     = 80
    protocol    = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }

  egress {
    from_port   = 0
    to_port     = 0
    protocol    = "-1"
    cidr_blocks = ["0.0.0.0/0"]
  }

  tags = {
    Name = "allow_web"
  }
}

# Launch an EC2 instance
resource "aws_instance" "web_server" {
  ami           = "ami-0c55b159cbfafe1f0"  # Amazon Linux 2 AMI
  instance_type = "t2.micro"
  subnet_id     = aws_subnet.main.id
  
  vpc_security_group_ids = [aws_security_group.allow_web.id]

  user_data = <<-EOF
              #!/bin/bash
              yum update -y
              yum install -y httpd
              systemctl start httpd
              systemctl enable httpd
              echo "Hello from the cloud!" > /var/www/html/index.html
              EOF

  tags = {
    Name = "Web Server"
  }
}

# Output the public IP of the instance
output "web_server_public_ip" {
  value = aws_instance.web_server.public_ip
}

This Terraform script sets up a basic cloud infrastructure on AWS, including a VPC, subnet, security group, and an EC2 instance running a simple web server. It demonstrates how Infrastructure as Code can be used to define and deploy cloud resources quickly and consistently.
