Billing accounts and budgets in GCP - Mini Project: Build & Apply

Billing Accounts and Budgets Setup in GCP

📖 Scenario: You are managing cloud costs for a small company using Google Cloud Platform (GCP). To keep track of spending and avoid surprises, you need to set up a billing account and create a budget with alerts.

🎯 Goal: Build a simple billing account configuration and a budget alert in GCP using Infrastructure as Code style. This will help monitor and control cloud expenses effectively.

📋 What You'll Learn

Create a billing account dictionary with exact fields

Add a budget threshold percentage variable

Create a budget configuration using the billing account and threshold

Complete the budget alert configuration with notification channels

💡 Why This Matters

🌍 Real World

Companies use billing accounts and budgets in GCP to monitor cloud spending and avoid unexpected charges.

💼 Career

Cloud engineers and financial operations teams set up budgets and alerts to manage costs and optimize cloud resource usage.

1

Create the billing account data structure

Create a dictionary called billing_account with these exact entries: 'account_id': '1234-5678-9012', 'display_name': 'Company Billing Account', and 'open': true.

GCP

# Create the billing_account dictionary with specified keys and values
# Your code here

Hint

Use curly braces to create a dictionary and include the keys and values exactly as shown.

2

Add a budget threshold percentage variable

Create a variable called budget_threshold_percent and set it to 0.8 to represent 80% of the budget.

GCP

billing_account = {
    'account_id': '1234-5678-9012',
    'display_name': 'Company Billing Account',
    'open': True
}
# Create budget_threshold_percent variable and set to 0.8
# Your code here

Hint

Use a simple assignment to create the variable with the exact name and value.

3

Create the budget configuration dictionary

Create a dictionary called budget with these exact entries: 'billing_account_id' set to billing_account['account_id'], 'amount' set to 1000, and 'threshold_rules' as a list containing a dictionary with 'threshold_percent' set to budget_threshold_percent.

GCP

billing_account = {
    'account_id': '1234-5678-9012',
    'display_name': 'Company Billing Account',
    'open': True
}
budget_threshold_percent = 0.8
# Create budget dictionary with billing_account_id, amount, and threshold_rules
# Your code here

Hint

Use the billing_account dictionary to get the account_id and create a list with one dictionary for threshold_rules.

4

Complete the budget alert configuration

Add a key 'notifications' to the budget dictionary. Set it to a list containing a dictionary with 'pubsub_topic' set to 'projects/my-project/topics/budget-alerts' and 'schema_version' set to '1.0'.

GCP

billing_account = {
    'account_id': '1234-5678-9012',
    'display_name': 'Company Billing Account',
    'open': True
}
budget_threshold_percent = 0.8
budget = {
    'billing_account_id': billing_account['account_id'],
    'amount': 1000,
    'threshold_rules': [
        {'threshold_percent': budget_threshold_percent}
    ]
}
# Add notifications key to budget with pubsub_topic and schema_version
# Your code here

Hint

Add the notifications key with a list containing a dictionary for the alert settings.

Practice

1. What is the main purpose of a billing account in Google Cloud Platform?

easy

A. To manage how you pay for cloud services

B. To create virtual machines

C. To store data securely

D. To monitor network traffic

Solution

1. Step 1: Understand billing account role

   A billing account is used to handle payments for cloud resources you use.

2. Step 2: Compare options with billing account function

   Creating VMs, storing data, and monitoring traffic are not billing functions.

3. Final Answer:

   To manage how you pay for cloud services -> Option A

4. Quick Check:

   Billing account = payment management [OK]

Hint: Billing accounts handle payments, not resource creation [OK]

Common Mistakes:

• Confusing billing account with resource management
• Thinking billing accounts store data
• Assuming billing accounts monitor traffic

2. Which of the following is the correct way to set a budget alert threshold in Google Cloud Console?

easy

A. Set a threshold based on number of users

B. Set a threshold percentage like 50% or 90% of the budget

C. Set a fixed number of API calls

D. Set a threshold using VM instance count

Solution

1. Step 1: Identify budget alert settings

   Budget alerts are set by percentage thresholds of the total budget amount.

2. Step 2: Eliminate unrelated options

   API calls, user count, and VM instances are not used for budget alert thresholds.

3. Final Answer:

   Set a threshold percentage like 50% or 90% of the budget -> Option B

4. Quick Check:

   Budget alerts use percentage thresholds [OK]

Hint: Budget alerts use percentage, not counts [OK]

Common Mistakes:

• Confusing budget thresholds with usage metrics
• Trying to set alerts by API calls or users
• Using resource counts for budget alerts

3. Consider this budget alert configuration:
Budget amount: $1000
Alert threshold: 80%
What happens when your spending reaches $800?

medium

A. You receive an alert notification

B. Your services are automatically stopped

C. Your budget resets to $0

D. Nothing happens until you reach $1000

Solution

1. Step 1: Calculate alert trigger amount

   80% of $1000 is $800, so alert triggers at $800 spending.

2. Step 2: Understand budget alert behavior

   Alerts notify you but do not stop services or reset budgets automatically.

3. Final Answer:

   You receive an alert notification -> Option A

4. Quick Check:

   Alert triggers at threshold spending [OK]

Hint: Alerts notify at threshold, no automatic stops [OK]

Common Mistakes:

• Thinking services stop automatically on alert
• Believing budget resets after alert
• Ignoring alert until full budget spent

4. You created a budget but never received any alert emails even after spending exceeded the threshold. What is the most likely cause?

medium

A. Budget amount was set to zero

B. Billing account was closed

C. Notification channels were not configured properly

D. Budget thresholds were set above 100%

Solution

1. Step 1: Check notification setup

   Alerts require notification channels like email to be configured to send alerts.

2. Step 2: Evaluate other options

   Budget zero or closed account would cause other errors; thresholds above 100% mean alerts never trigger.

3. Final Answer:

   Notification channels were not configured properly -> Option C

4. Quick Check:

   Alerts need notification channels [OK]

Hint: Check notification setup if no alerts received [OK]

Common Mistakes:

• Ignoring notification channel setup
• Assuming budget zero triggers alerts
• Setting thresholds above 100%

5. You want to create a budget that alerts you at 50%, 75%, and 90% of your spending limit. Which approach correctly sets this up in Google Cloud?

hard

A. Use billing export to BigQuery and write custom queries for alerts

B. Create three separate budgets each with one alert threshold

C. Set a single alert threshold at 90% and manually check earlier spending

D. Create one budget with multiple alert thresholds at 50%, 75%, and 90%

Solution

1. Step 1: Understand budget alert capabilities

   Google Cloud budgets support multiple alert thresholds in one budget.

2. Step 2: Compare options for efficiency

   One budget with multiple thresholds is simpler and recommended over multiple budgets or manual checks.

3. Step 3: Consider advanced options

   Billing export is for custom analysis, not needed for standard alerts.

4. Final Answer:

   Create one budget with multiple alert thresholds at 50%, 75%, and 90% -> Option D

5. Quick Check:

   Multiple thresholds in one budget [OK]

Hint: Use one budget with multiple thresholds for alerts [OK]

Common Mistakes:

• Creating multiple budgets unnecessarily
• Relying on manual checks instead of alerts
• Using billing export for simple alerts
