Azure Cost Analysis tool - Mini Project: Build & Apply

Azure Cost Analysis Tool

📖 Scenario: You are managing cloud expenses for a small company using Microsoft Azure. To keep track of costs, you want to build a simple Azure Cost Analysis tool that helps you see the spending per service.

🎯 Goal: Create a basic Azure Cost Analysis tool that stores cost data for different Azure services, sets a budget threshold, calculates total costs, and identifies services exceeding the budget.

📋 What You'll Learn

Create a dictionary with exact Azure services and their monthly costs

Add a budget threshold variable

Calculate the total monthly cost using a loop

Identify and list services that exceed the budget threshold

💡 Why This Matters

🌍 Real World

Cloud cost management is essential for businesses to avoid overspending and optimize resource usage. This project simulates a simple cost analysis tool to help monitor Azure expenses.

💼 Career

Understanding how to analyze and manage cloud costs is a key skill for cloud administrators, DevOps engineers, and cloud architects.

1

Create Azure services cost data

Create a dictionary called azure_costs with these exact entries: 'Virtual Machines': 120, 'Storage': 80, 'App Services': 50, 'SQL Database': 100, 'Networking': 40

Azure

# Create the dictionary azure_costs with the exact service names and costs
# Your code here

Hint

Use a Python dictionary with service names as keys and costs as values.

2

Set budget threshold

Create a variable called budget_threshold and set it to 90

Azure

azure_costs = {
    'Virtual Machines': 120,
    'Storage': 80,
    'App Services': 50,
    'SQL Database': 100,
    'Networking': 40
}
# Create the budget_threshold variable and set it to 90
# Your code here

Hint

Use a simple variable assignment for the budget threshold.

3

Calculate total monthly cost

Create a variable called total_cost and set it to 0. Then use a for loop with variables service and cost to iterate over azure_costs.items() and add each cost to total_cost

Azure

azure_costs = {
    'Virtual Machines': 120,
    'Storage': 80,
    'App Services': 50,
    'SQL Database': 100,
    'Networking': 40
}
budget_threshold = 90
# Calculate total_cost by summing all costs in azure_costs
# Your code here

Hint

Initialize total_cost to zero before the loop. Use the loop to add each cost.

4

Identify services exceeding budget

Create a list called over_budget_services and set it to an empty list. Then use a for loop with variables service and cost to iterate over azure_costs.items(). Inside the loop, if cost is greater than budget_threshold, append service to over_budget_services

Azure

azure_costs = {
    'Virtual Machines': 120,
    'Storage': 80,
    'App Services': 50,
    'SQL Database': 100,
    'Networking': 40
}
budget_threshold = 90
total_cost = 0
for service, cost in azure_costs.items():
    total_cost += cost
# Create over_budget_services list and add services with cost > budget_threshold
# Your code here

Hint

Use a second loop to check costs against the budget and add the service names to the list.

Practice

1. What is the main purpose of the Azure Cost Analysis tool?

easy

A. To monitor network traffic

B. To create virtual machines

C. To track and understand your cloud spending

D. To manage user access permissions

Solution

1. Step 1: Understand the tool's function

   The Azure Cost Analysis tool is designed to help users see how much they spend on cloud services.

2. Step 2: Compare options with tool purpose

   The remaining options relate to other Azure services like VM creation, network monitoring, or access management, not cost tracking.

3. Final Answer:

   To track and understand your cloud spending -> Option C

4. Quick Check:

   Cost Analysis = Spending tracking [OK]

Hint: Cost Analysis = Understand cloud spending fast [OK]

Common Mistakes:

• Confusing cost analysis with resource creation
• Mixing cost tracking with security management
• Thinking it monitors network or performance

2. Which of the following is the correct way to filter costs by resource group in Azure Cost Analysis?

easy

A. Create a new virtual machine in the resource group

B. Select the 'Resource Group' filter and choose the desired group

C. Use the Azure CLI to list resource groups

D. Enable diagnostic logs on the resource group

Solution

1. Step 1: Identify filtering method in Cost Analysis

   Azure Cost Analysis allows filtering by selecting filters like 'Resource Group' from the interface.

2. Step 2: Eliminate unrelated options

   Creating VMs, using CLI to list groups, or enabling logs relate to resource management, not filtering costs in the UI.

3. Final Answer:

   Select the 'Resource Group' filter and choose the desired group -> Option B

4. Quick Check:

   Filter by resource group = Select filter [OK]

Hint: Use built-in filters to narrow cost views [OK]

Common Mistakes:

• Confusing filtering with resource creation
• Using CLI commands instead of UI filters
• Thinking logs filter costs

3. You apply a filter for the last 7 days in Azure Cost Analysis and see a chart showing daily costs. What does the chart represent?

medium

A. The total cost for each day in the last 7 days

B. The number of virtual machines created each day

C. The network traffic volume per day

D. The number of users logged in each day

Solution

1. Step 1: Understand the filter effect

   Filtering by last 7 days in Cost Analysis shows cost data for each day in that period.

2. Step 2: Interpret the chart meaning

   The chart displays daily spending totals, not resource counts or traffic.

3. Final Answer:

   The total cost for each day in the last 7 days -> Option A

4. Quick Check:

   Filter by date = daily cost chart [OK]

Hint: Date filter shows daily cost totals [OK]

Common Mistakes:

• Confusing cost with resource counts
• Assuming charts show network or user data
• Ignoring the filter's time range effect

4. You tried to filter costs by a tag in Azure Cost Analysis but see no results. What is the most likely reason?

medium

A. You need to restart the Azure portal

B. The Azure subscription is expired

C. The Cost Analysis tool is offline

D. The resources do not have the specified tag applied

Solution

1. Step 1: Check tag usage

   Filtering by tag shows results only if resources have that tag assigned.

2. Step 2: Rule out unrelated causes

   Subscription expiry, tool offline, or portal restart do not cause empty tag filter results.

3. Final Answer:

   The resources do not have the specified tag applied -> Option D

4. Quick Check:

   No tag results = missing tag on resources [OK]

Hint: No results? Check if tag exists on resources [OK]

Common Mistakes:

• Assuming tool or portal is broken
• Blaming subscription status incorrectly
• Not verifying tag presence on resources

5. Your company wants to reduce unexpected cloud costs. How can you use Azure Cost Analysis to help achieve this?

hard

A. Set up regular cost reviews with filters for departments and resource types

B. Delete all virtual machines immediately

C. Disable all Azure services to stop billing

D. Ignore cost reports and focus on performance

Solution

1. Step 1: Identify cost management strategy

   Regular reviews with filters help spot high spending areas and control budgets.

2. Step 2: Evaluate options for cost control

   Deleting all VMs or disabling services is impractical; ignoring reports misses cost issues.

3. Final Answer:

   Set up regular cost reviews with filters for departments and resource types -> Option A

4. Quick Check:

   Regular filtered reviews = cost control [OK]

Hint: Review costs regularly by department and resource [OK]

Common Mistakes:

• Thinking deleting all resources is a solution
• Ignoring cost data leads to surprises
• Disabling services stops usage but is not practical
