Process Flow - Setting up billing alerts

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

Look at the execution_table, at which step does the CloudWatch alarm change state to ALARM?

A Step 5

B Step 7

C Step 6

D Step 4

💡 Hint

Check the 'CloudWatch Alarm State' column in execution_table row for step 6

According to variable_tracker, what is the email subscription status after step 3?

A Pending

B Confirmed

C None

D Failed

💡 Hint

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

If the user never confirms the email subscription, what will happen to notifications?

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.
