Load balancing rules in Azure - Mini Project: Build & Apply

Azure Load Balancing Rules Setup

📖 Scenario: You are setting up a simple Azure load balancer to distribute incoming traffic evenly to two virtual machines. This helps keep your website available and responsive even if one server is busy.

🎯 Goal: Create an Azure load balancer with a load balancing rule that forwards HTTP traffic on port 80 to backend virtual machines.

📋 What You'll Learn

Create a frontend IP configuration named frontendIPConfig

Create a backend address pool named backendPool

Create a health probe named healthProbe on port 80

Create a load balancing rule named httpRule that uses the frontend IP, backend pool, and health probe to forward TCP traffic on port 80

💡 Why This Matters

🌍 Real World

Load balancers help websites and apps stay available and fast by spreading user requests across multiple servers.

💼 Career

Understanding load balancing rules is essential for cloud engineers and architects managing scalable and reliable cloud services.

1

Create frontend IP configuration

Create a variable called frontend_ip_config as a dictionary with the keys name set to "frontendIPConfig" and private_ip_address set to "10.0.0.5".

Azure

# Create the frontend IP configuration dictionary
# Your code here

Need a hint?

Think of the frontend IP as the address where users connect to your load balancer.

2

Create backend address pool

Create a variable called backend_address_pool as a dictionary with the key name set to "backendPool".

Azure

frontend_ip_config = {
    "name": "frontendIPConfig",
    "private_ip_address": "10.0.0.5"
}

# Create the backend address pool dictionary
# Your code here

Need a hint?

The backend pool holds the servers that will receive the traffic.

3

Create health probe

Create a variable called health_probe as a dictionary with keys name set to "healthProbe", protocol set to "Tcp", and port set to 80.

Azure

frontend_ip_config = {
    "name": "frontendIPConfig",
    "private_ip_address": "10.0.0.5"
}

backend_address_pool = {
    "name": "backendPool"
}

# Create the health probe dictionary
# Your code here

Need a hint?

The health probe checks if backend servers are healthy by connecting on port 80.

4

Create load balancing rule

Create a variable called load_balancing_rule as a dictionary with keys: name set to "httpRule", frontend_ip_configuration set to frontend_ip_config, backend_address_pool set to backend_address_pool, probe set to health_probe, protocol set to "Tcp", frontend_port set to 80, and backend_port set to 80.

Azure

frontend_ip_config = {
    "name": "frontendIPConfig",
    "private_ip_address": "10.0.0.5"
}

backend_address_pool = {
    "name": "backendPool"
}

health_probe = {
    "name": "healthProbe",
    "protocol": "Tcp",
    "port": 80
}

# Create the load balancing rule dictionary
# Your code here

Need a hint?

The load balancing rule connects the frontend IP, backend pool, and health probe to forward traffic on port 80.
