What is Billing account in GCP?

• Google Cloud Billing defines billing accounts linked to Google Cloud Projects to determine who pays for a given set of Google Cloud resources.

Cloud Billing Concepts

Resource Hierarchy

• Google Cloud resources are organized hierarchically i.e. Organization -> Folder -> Project -> Resources
• Resource hierarchy allows mapping of organization’s operational structure to Google Cloud, and to manage access control and permissions for groups of related resources.
• Both IAM & Organization policies are inherited through the hierarchy, and the effective policy at each node of the hierarchy is the result of policies directly applied at the node and policies inherited from its ancestors

Cloud Billing Account

• is a cloud-level resource managed in the Cloud Console.
• tracks all of the costs (charges and usage credits) incurred by the Google Cloud usage
  • A Cloud Billing account can be linked to one or more projects.
  • Project usage is charged to the linked Cloud Billing account.
• results in a single invoice per Cloud Billing account
• operates in a single currency
• defines who pays for a given set of resources
• has billing-specific roles and permissions to control accessing and modifying billing-related functions (established by IAM roles)

Cloud Billing IAM Roles

• To move the project to a different billing account, you must be a billing administrator and the project owner.

Budgets and Budgets Alerts

• Cloud Billing budgets can be created to monitor all of the Google Cloud charges in one place.
• Budget enables tracking of actual Google Cloud spend against the planned spend.
• Budget alert threshold rules can be set that are used to trigger email notifications based on the set budget amount.
• Budget alert emails help track the spend against the set budget.
• Budgets can also be used to automate cost control responses.
• Pub/Sub can be used for programmatic notifications for e.g. to forward budget messages to other mediums or to automate cost management tasks
  
  

Cloud Billing Export

• Cloud Billing export to BigQuery enables exporting detailed Google Cloud billing data (such as usage, cost estimates, and pricing data) automatically throughout the day to a specified BigQuery dataset
• Cloud Billing data from BigQuery can be accessed for detailed analysis, or visualized using a tool like Google Data Studio to visualize your data.
• Google Cloud billing data is not added retroactively, so you won’t see Cloud Billing data from before you enable export.
• Google Cloud recommends enabling Cloud Billing data export to BigQuery at the same time that you create a Cloud Billing account.
• Cloud Billing data exporting to a JSON or CSV file is not deprecated

GCP Certification Exam Practice Questions

• Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).
• GCP services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
• GCP exam questions are not updated to keep up the pace with GCP updates, so even if the underlying feature has changed the question might not be updated
• Open to further feedback, discussion and correction.

1. Your company has created a new billing account and needs to move the projects to the billing account. What roles are needed to change the billing account? (Select two)
   1. Project Billing manager
   2. Project Owner
   3. Billing Account Administrator
   4. Billing Account Manager
   5. Project Editor
2. You are the team lead of a group of 10 developers. You provided each developer with an individual Google Cloud Project that they can use as their personal sandbox to experiment with different Google Cloud solutions. You want to be notified if any of the developers are spending above $500 per month on their sandbox environment. What should you do?
   1. Create a single budget for all projects and configure budget alerts on this budget.
   2. Create a separate billing account per sandbox project and enable BigQuery billing exports. Create a Data Studio dashboard to plot the spending per billing account.
   3. Create a budget per project and configure budget alerts on all of these budgets.
   4. Create a single billing account for all sandbox projects and enable BigQuery billing exports. Create a Data Studio dashboard to plot the spending per project.
3. Your finance team wants to view the billing report for your projects. You want to make sure that the finance team does not get additional permissions to the project. What should you do?
   1. Add the group for the finance team to roles/billing.user role.
   2. Add the group for the finance team to roles/billing.admin role.
   3. Add the group for the finance team to roles/billing.viewer role.
   4. Add the group for the finance team to roles/billing.projectManager role.
