Application Gateway (Layer 7) in Azure - Mini Project: Build & Apply

Create an Azure Application Gateway (Layer 7)

📖 Scenario: You are setting up a web application in Azure that needs a secure and scalable entry point. To manage traffic and provide features like SSL termination and URL-based routing, you will create an Azure Application Gateway, which works at Layer 7 (the application layer).

🎯 Goal: Build an Azure Application Gateway with a frontend IP configuration, backend pool, HTTP settings, and a basic routing rule to direct traffic to the backend pool.

📋 What You'll Learn

Create a resource group variable named resource_group with the value "MyResourceGroup".

Create an Application Gateway configuration variable named app_gateway_config with the basic settings.

Add a backend pool named backend_pool with one backend IP address "10.0.1.4".

Add a routing rule named routing_rule that connects the frontend IP to the backend pool using HTTP settings.

💡 Why This Matters

🌍 Real World

Application Gateways are used in real-world cloud deployments to manage web traffic securely and efficiently, providing features like load balancing, SSL termination, and web application firewall.

💼 Career

Understanding how to configure Application Gateways is essential for cloud engineers and architects working with Azure to build scalable and secure web applications.

1

Create the resource group variable

Create a variable called resource_group and set it to the string "MyResourceGroup".

Azure

# Your code here

Need a hint?

Use a simple string assignment to create the resource group variable.

2

Define the basic Application Gateway configuration

Create a dictionary called app_gateway_config with keys "name" set to "myAppGateway", "location" set to "eastus", and "sku" set to "Standard_v2".

Azure

resource_group = "MyResourceGroup"
# Your code here

Need a hint?

Use a dictionary with the exact keys and values as specified.

3

Add a backend pool with one backend IP address

Add a key "backend_pools" to app_gateway_config with a list containing one dictionary. This dictionary should have the key "name" set to "backend_pool" and "backend_addresses" set to a list with one dictionary containing "ip_address" set to "10.0.1.4".

Azure

resource_group = "MyResourceGroup"
app_gateway_config = {
    "name": "myAppGateway",
    "location": "eastus",
    "sku": "Standard_v2"
}
# Your code here

Need a hint?

Remember to add the backend_pools key with a list of dictionaries as described.

4

Add a routing rule connecting frontend IP to backend pool

Add keys "frontend_ip_config", "http_settings", and "routing_rule" to app_gateway_config. Set "frontend_ip_config" to a dictionary with "name" as "frontendIP" and "public_ip_address" as "20.30.40.50". Set "http_settings" to a dictionary with "name" as "httpSettings" and "port" as 80. Set "routing_rule" to a dictionary with "name" as "rule1", "frontend_ip_config" as "frontendIP", "backend_pool" as "backend_pool", and "http_settings" as "httpSettings".

Azure

resource_group = "MyResourceGroup"
app_gateway_config = {
    "name": "myAppGateway",
    "location": "eastus",
    "sku": "Standard_v2",
    "backend_pools": [
        {
            "name": "backend_pool",
            "backend_addresses": [
                {"ip_address": "10.0.1.4"}
            ]
        }
    ]
}
# Your code here

Need a hint?

Add the frontend_ip_config, http_settings, and routing_rule keys exactly as described to complete the Application Gateway configuration.
