This flow shows how AWS billing alerts are set up: enable alerts, create notification topic, subscribe email, create alarm, and send alert when cost exceeds threshold.

Execution Sample

AWS

1. Enable billing alerts in AWS
2. Create SNS topic 'BillingAlerts'
3. Subscribe [e-mail] to SNS
4. Create CloudWatch alarm for billing > $100
5. Alarm triggers and sends notification

This sequence sets up an alert to notify the user by email when AWS billing exceeds $100.

Process Table

Step	Action	AWS Service	Result	Notes
1	Enable billing alerts	AWS Billing	Billing data available in CloudWatch	Required to monitor costs
2	Create SNS topic 'BillingAlerts'	SNS	SNS topic created	Topic will send notifications
3	Subscribe email [e-mail]	SNS	Subscription pending confirmation	User must confirm subscription via email
4	Confirm subscription	SNS	Subscription confirmed	User ready to receive alerts
5	Create CloudWatch alarm for billing > $100	CloudWatch	Alarm created and enabled	Monitors estimated charges
6	Billing exceeds $100	CloudWatch	Alarm state changes to ALARM	Triggers notification
7	Send notification to SNS topic	SNS	Notification sent to subscribers	User receives alert email
8	User receives email alert	Email	User notified of billing threshold breach	Alert successful
9	Billing below threshold	CloudWatch	Alarm state OK	No notification sent
10	End	-	-	Process complete

💡 Process stops after alert sent or billing remains below threshold

Key Moments - 3 Insights

Why do I need to confirm the email subscription before receiving alerts?

The email subscription status changes from 'Pending' to 'Confirmed' only after the user clicks the confirmation link in the email (see execution_table step 4). Without confirmation, notifications won't be delivered.

What happens if billing never exceeds the threshold?

The CloudWatch alarm state remains 'OK' (execution_table step 9), so no notification is sent and the process waits for billing changes.

Can I receive alerts without enabling billing alerts in AWS?

No, enabling billing alerts (step 1) is required to make billing data available in CloudWatch for monitoring and alerting.

Visual Quiz - 3 Questions

💡 Hint

Look at 'Email Subscription Status' variable after step 2 and step 4 in variable_tracker

A Notifications will be sent anyway

B Notifications will not be sent

C Notifications will be delayed

D Notifications will be sent to a default email

💡 Hint

Refer to key_moments about email subscription confirmation and execution_table step 4

Concept Snapshot

Setting up AWS billing alerts:
1. Enable billing alerts in your AWS account.
2. Create an SNS topic for notifications.
3. Subscribe your email and confirm it.
4. Create a CloudWatch alarm on billing threshold.
5. When billing exceeds threshold, alarm triggers SNS to send email alert.
6. Alerts help you monitor and control AWS costs.

Full Transcript

To set up billing alerts in AWS, first enable billing alerts in your account so billing data is available in CloudWatch. Next, create an SNS topic to send notifications. Subscribe your email to this topic and confirm the subscription by clicking the link sent to your email. Then create a CloudWatch alarm that monitors your billing costs and triggers when costs exceed your set threshold, for example $100. When the alarm triggers, it sends a notification to the SNS topic, which then emails you the alert. If billing stays below the threshold, no alert is sent. This process helps you stay informed about your AWS spending and avoid surprises.

Practice

1. What is the primary purpose of setting up billing alerts in AWS?

easy

A. To disable services when spending is high

B. To automatically increase your cloud budget

C. To get notified when your cloud spending reaches a certain limit

D. To get detailed logs of all service usage

Solution

1. Step 1: Understand billing alerts purpose

   Billing alerts notify you when your spending reaches a set threshold to help control costs.

2. Step 2: Compare options

   Only To get notified when your cloud spending reaches a certain limit describes notification on spending limits; others describe unrelated actions.

3. Final Answer:

   To get notified when your cloud spending reaches a certain limit -> Option C

4. Quick Check:

   Billing alerts = notifications on spending [OK]

Hint: Billing alerts notify you about spending limits reached [OK]

Common Mistakes:

• Thinking alerts automatically change budgets
• Confusing alerts with service shutdown
• Assuming alerts provide detailed usage logs

2. Which AWS service is used to create billing alerts easily?

easy

A. Amazon S3

B. AWS CloudTrail

C. AWS Lambda

D. AWS Budgets

Solution

1. Step 1: Identify service for billing alerts

   AWS Budgets is designed to create budgets and alerts for billing thresholds.

2. Step 2: Eliminate unrelated services

   CloudTrail tracks API calls, Lambda runs code, S3 stores data; none create billing alerts.

3. Final Answer:

   AWS Budgets -> Option D

4. Quick Check:

   AWS Budgets = billing alerts service [OK]

Hint: Use AWS Budgets to set billing alerts quickly [OK]

Common Mistakes:

• Choosing CloudTrail for billing alerts
• Confusing Lambda with alert setup
• Selecting S3 as billing alert tool

3. Given this AWS Budgets alert setup:
Threshold: 80% of $1000 budget
Notification: Email to [e-mail]
What triggers the alert?

medium

A. When spending reaches $800

B. When spending reaches $1000

C. When spending reaches $200

D. When spending reaches $1200

Solution

1. Step 1: Calculate 80% of $1000 budget

   80% of $1000 = 0.8 x 1000 = $800.

2. Step 2: Understand alert trigger

   The alert triggers when spending reaches $800, the threshold set.

3. Final Answer:

   When spending reaches $800 -> Option A

4. Quick Check:

   80% x 1000 = 800 [OK]

Hint: Multiply budget by threshold percent to find alert trigger [OK]

Common Mistakes:

• Using full budget amount instead of threshold
• Confusing 80% with 20%
• Choosing amounts above budget

4. You set a billing alert but never receive notifications. What is a likely cause?

medium

A. Your AWS account has no budget set

B. You did not verify the email address for notifications

C. Billing alerts only work with SMS, not email

D. Alerts only trigger after spending exceeds twice the budget

Solution

1. Step 1: Check notification setup requirements

   AWS requires email addresses to be verified before sending alerts.

2. Step 2: Evaluate other options

   A budget is required to create alerts; alerts support email notifications; alerts trigger when spending reaches the threshold, not after twice the budget.

3. Final Answer:

   You did not verify the email address for notifications -> Option B

4. Quick Check:

   Email verification needed for alerts [OK]

Hint: Verify email to receive AWS billing alerts [OK]

Common Mistakes:

• Assuming alerts work without email verification
• Thinking alerts only support SMS
• Believing alerts trigger only after double spending

5. You want to set a billing alert that notifies you by email when your AWS spending exceeds $500 and again at $750. How can you configure this using AWS Budgets?

hard

A. Create one budget with two notification thresholds: 50% and 75% of $1000 budget

B. Create two separate budgets each with one notification at $500 and $750

C. Create one budget with a single notification at $625 (average of $500 and $750)

D. Create one budget with a notification only at $750 and manually check for $500

Solution

1. Step 1: Understand AWS Budgets notification capabilities

   AWS Budgets allows multiple notification thresholds per budget.

2. Step 2: Apply thresholds to a single budget

   Set budget at $1000 with notifications at 50% ($500) and 75% ($750) to get alerts at both amounts.

3. Step 3: Evaluate other options

   Creating two budgets is unnecessary; a single notification at the average misses the exact alert points; manual checking is inefficient.

4. Final Answer:

   Create one budget with two notification thresholds: 50% and 75% of $1000 budget -> Option A

5. Quick Check:

   Multiple notifications per budget = correct setup [OK]

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

Common Mistakes:

• Creating multiple budgets instead of multiple notifications
• Using average threshold instead of exact values
• Relying on manual checks instead of alerts
