Zorluk: OrtaCreating Billing Budgets, Alerts, and BigQuery Exports

A Cloud Engineer needs to establish automated cost controls by configuring a Cloud Billing budget to publish programmatic threshold notifications to a Cloud Pub/Sub topic. What is the correct sequence of steps to perform this configuration?

  1. 1Create a Cloud Pub/Sub topic in the Google Cloud project assigned to handle billing automation.
  2. 2Grant the Pub/Sub Publisher IAM role (roles/pubsub.publisher) on the topic to the Cloud Billing service account.
  3. 3Navigate to the Cloud Billing console and select Budgets & alerts for the target billing account.
  4. 4Create a new budget, specify the scope and target amount, and define the percentage cost threshold rules.
  5. 5Under Actions in the budget setup, enable programmatic notifications and select the created Pub/Sub topic.

Cevap

The correct sequence of steps is: 1) Create the Cloud Pub/Sub topic, 2) Grant the Pub/Sub Publisher role to the Cloud Billing service account, 3) Open Budgets & alerts in the Cloud Billing console, 4) Configure the budget scope, target amount, and threshold rules, and 5) Enable programmatic notifications and select the Pub/Sub topic under budget Actions.
Configuring programmatic billing notifications requires establishing the messaging infrastructure before linking it to budget rules. First, the Cloud Pub/Sub topic must be created. Next, the Cloud Billing service account must be granted `roles/pubsub.publisher` access so it has permission to publish messages. Once infrastructure authorization is ready, the engineer opens the Budgets & alerts interface in Cloud Billing, defines the budget limits and threshold rules, and finally connects the budget to the target Pub/Sub topic under Actions.

Adım Adım Çözüm

1
Provision the Pub/Sub notification endpoint.
A Cloud Pub/Sub topic is established in the project.
Creating the Pub/Sub topic first ensures that a valid target resource exists before configuring access policies or budget actions.
2
Authorize the Cloud Billing backend service.
The Cloud Billing service account is assigned the Pub/Sub Publisher role on the newly created topic.
Without explicit publisher permissions on the target topic, Cloud Billing cannot deliver automated notification messages when thresholds are reached.
3
Open billing management tools.
The engineer accesses the Budgets & alerts section within Cloud Billing.
This console location provides the controls required to create and manage billing budget alerting rules.
4
Define budget targets and alert triggers.
Budget scope, spending limit, and percentage thresholds (e.g., 50%, 90%, 100%) are set up.
Establishing threshold rules specifies the exact spending conditions under which notification events will fire.
5
Connect the budget to the programmatic Pub/Sub endpoint.
The budget is linked to the Pub/Sub topic under the Actions configuration panel.
This final binding enables programmatic notification messages to be published to the topic upon threshold breaches.
