Cost monitoring and budgets in Firebase - Mini Project: Build & Apply

Firebase Cost Monitoring and Budget Alerts

📖 Scenario: You are managing a Firebase project for a small app. You want to keep track of your monthly spending to avoid surprises. Setting up a budget alert helps you get notified when costs approach your limit.

🎯 Goal: Build a simple Firebase budget alert setup that monitors your monthly spending and sends an alert when the cost reaches a set threshold.

📋 What You'll Learn

Create a Firebase project cost data structure with exact monthly spending values

Add a budget threshold variable to set the alert limit

Write logic to check if spending exceeds the threshold

Print an alert message if the budget is exceeded

💡 Why This Matters

🌍 Real World

Firebase projects often have usage costs. Monitoring spending helps avoid unexpected charges and keeps projects within budget.

💼 Career

DevOps and cloud engineers use cost monitoring and budget alerts to manage cloud resources efficiently and control expenses.

1

Create Firebase monthly spending data

Create a dictionary called monthly_spending with these exact entries: 'January': 120, 'February': 150, 'March': 90, 'April': 200

Firebase

# Create the monthly_spending dictionary with exact values
# Your code here

Need a hint?

Use curly braces to create a dictionary with the month names as keys and spending amounts as values.

2

Set the budget threshold

Create a variable called budget_limit and set it to 400 to represent the monthly budget limit.

Firebase

monthly_spending = {'January': 120, 'February': 150, 'March': 90, 'April': 200}
# Set the budget_limit variable to 400
# Your code here

Need a hint?

Just assign the number 400 to the variable named budget_limit.

3

Check if spending exceeds the budget

Create a variable called total_spent that sums all values in monthly_spending. Then create a variable called is_over_budget that is true if total_spent is greater than budget_limit, otherwise false.

Firebase

monthly_spending = {'January': 120, 'February': 150, 'March': 90, 'April': 200}
budget_limit = 400
# Calculate total_spent and check if it exceeds budget_limit
# Your code here

Need a hint?

Use the sum() function on the dictionary values to get total_spent. Then compare total_spent with budget_limit to set is_over_budget.

4

Print budget alert message

Write a print statement that outputs exactly "Alert: Budget exceeded! Total spent: 560" if is_over_budget is true. Otherwise, print "Budget is within limit."

Firebase

monthly_spending = {'January': 120, 'February': 150, 'March': 90, 'April': 200}
budget_limit = 400
total_spent = sum(monthly_spending.values())
is_over_budget = total_spent > budget_limit
# Print the alert message based on is_over_budget
# Your code here

Need a hint?

Use an if statement to check is_over_budget and print the exact alert message using an f-string.
