Why cost management matters in Azure - Why It Works

Introduction

Cloud services can quickly become expensive if not monitored. Cost management helps you track and control your spending to avoid surprises and waste.

When you want to avoid unexpected high bills from cloud usage.

When you need to allocate cloud costs fairly across different teams or projects.

When you want to find and stop paying for unused or underused resources.

When you plan to optimize your cloud setup to save money.

When you want to forecast future cloud expenses for budgeting.

Commands

This command queries your Azure cloud usage costs for the current month, showing daily spending to help you understand where your money goes.

Terminal

Expected Output

UsageDate  | Cost

2024-06-01 | 12.34

2024-06-02 | 15.67

2024-06-03 | 14.89

...

→

--type - Specifies the type of cost data to query, here usage costs.

→

--timeframe - Defines the period for the cost data, here from the start of the month to today.

This command creates a monthly cost report export to a storage account, so you can review or share detailed cost data later.

Terminal

az costmanagement export create --name MonthlyCostReport --type Usage --timeframe MonthToDate --storage-account mycoststorage --container costreports

Expected Output

Export 'MonthlyCostReport' created successfully.

→

--name - Names the export report.

→

--storage-account - Specifies where to save the exported report.

This command sets a monthly budget of $500 to help you control spending and get alerts if costs approach this limit.

Terminal

az costmanagement budget create --name ProjectBudget --amount 500 --time-grain Monthly --category Cost

Expected Output

Budget 'ProjectBudget' created successfully.

→

--amount - Sets the spending limit.

→

--time-grain - Defines how often the budget resets, here monthly.

This command shows the details of your budget, so you can check how much you have spent and how much remains.

Terminal

az costmanagement budget show --name ProjectBudget

Expected Output

Name: ProjectBudget

Amount: 500

Time Grain: Monthly

Current Spend: 120

Status: On Track

Key Concept

If you remember nothing else from this pattern, remember: tracking and controlling cloud costs early prevents surprises and saves money.

Common Mistakes

Ignoring cost reports and budgets until bills arrive.

This leads to unexpected high charges and no time to adjust usage.

Regularly check cost reports and set budgets to monitor spending proactively.

Not setting a budget or alerts in Azure Cost Management.

Without budgets, you have no automatic warnings about overspending.

Create budgets with alerts to get notified before costs get too high.

Exporting cost data to an inaccessible or wrong storage account.

You won't be able to review or share cost reports properly.

Verify storage account and container names before exporting cost reports.

Summary

Use Azure CLI commands to query and export your cloud usage costs.

Set budgets to control spending and receive alerts.

Regularly review cost data to avoid surprises and optimize expenses.
