Azure Load Balancer ARM Template – Ready-to-Deploy Reusable Solution
Azure Load Balancer ARM Template – Ready-to-Deploy Reusable Solution
Overview
This deployment package provides a fully configured Azure Load Balancer using Azure Resource Manager (ARM) templates.
The solution deploys a Standard Load Balancer with a public IP address, a frontend configuration, a backend pool, a health probe, and a load balancing rule.
What This Template Deploys
- Azure Public IP (Standard, Static)
- Azure Load Balancer (Standard SKU)
- Frontend IP Configuration
- Backend Address Pool
- Health probe (TCP Port 80)
- Load balancing rule (Port 80)
Files Included
template.json
ARM template defining the Load Balancer and Public IP
parameters.json
Parameter file used to Customize Deployment Values
deploy.ps1
PowerShell script for validation, What-If, and Deployment
Prerequisites
To use this template, you will need:
- An active Azure subscription
- Access to Azure Portal or Azure Cloud Shell
- Azure PowerShell (optional if using Cloud Shell)
Important Design Note
This template creates the Load Balancer Infrastructure Only.
It does NOT:
- Attach virtual machines
- Configure network interfaces
- Route live traffic
Backend pool is intentionally empty and must be populated separately.
How to Deploy
Step 1: Update Parameters
Open **parameters.json** and update:
- lbName
Name of the Load Balancer
- publicIpName
Name of the Public IP resource
- location
Example: eastus
Step 2: Upload Files (Cloud Shell)
Upload:
- template.json
- parameters.json
- deploy.ps1
Step 3: Run Deployment Script
The script supports three modes:
Validate (recommended first)
```powershell
.\deploy.ps1 -resourceGroupName RG-ARM-TEMPLATES -mode Validate
Deployment Behavior
The script performs:
Resource group validation or creation
Template validation or preview (based on mode)
Optional deployment
After deployment: Expected Result
Public IP is created
The load balancer is provisioned
Frontend, backend pool, probe, and rule are configured
Important Notes
Backend Configuration Required
To make the Load Balancer functional, you must:
Attach virtual machine NICs to the Backend Pool
Ensure NSG Rules allow required Traffic
Standard SKU Behavior
Requires explicit Network Configuration
Does not allow Implicit Inbound Traffic
More secure than Basic SKU
Cost Note
Standard Public IP → Small Cost
Standard Load Balancer → Small Cost
Deploy only when needed.
Summary
This package provides a reusable Azure Load Balancer deployment solution with a clean, production-ready baseline, enabling consistent and secure network Load-Balancing configuration.
