Code Example: Deploying a Simple Web Application to the Cloud

To provide a practical illustration of working with cloud infrastructure, let’s look at a simple example of deploying a web application to a cloud platform using Infrastructure as Code (IaC). In this example, we’ll use Terraform to provision resources on AWS.

# Configure the AWS provider
provider "aws" {
  region = "us-west-2"
}

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

# Create a public subnet
resource "aws_subnet" "public" {
  vpc_id     = aws_vpc.main.id
  cidr_block = "10.0.1.0/24"
  
  tags = {
    Name = "Public Subnet"
  }
}

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

  ingress {
    description = "HTTP from anywhere"
    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.public.id
  
  vpc_security_group_ids = [aws_security_group.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 does the following:

1. Configures the AWS provider
2. Creates a VPC and a public subnet
3. Sets up a security group to allow inbound HTTP traffic
4. Launches an EC2 instance with a simple web server
5. Outputs the public IP address of the instance

To use this script, you would need to have Terraform installed and configured with your AWS credentials. You can then run terraform init to initialize the working directory, followed by terraform apply to create the resources in your AWS account.

This example demonstrates how cloud infrastructure can be provisioned and managed using code, enabling version control, repeatability, and automation of infrastructure deployment.
