AWS Billing and Cost Management

  • AWS Billing and Cost Management is the service that you use to pay AWS bill, monitor your usage, and budget your costs

Analyzing Costs with Graphs

  • AWS provides Cost Explorer tool which allows filter graphs by API operations, Availability Zones, AWS service, custom cost allocation tags, EC2 instance type, purchase options, region, usage type, usage type groups, or, if Consolidated Billing used, by linked account.

Budgets

  • Budgets can be used to track AWS costs to see usage-to-date and current estimated charges from AWS
  • Budgets use the cost visualization provided by Cost Explorer to show the status of the budgets and to provide forecasts of your estimated costs.
  • Budgets can be used to create CloudWatch alarms that notify when you go over your budgeted amounts, or when the estimated costs exceed budgets
  • Notifications can be sent to an SNS topic and to email addresses associated with your budget notification

Cost Allocation Tags

  • Tags can be used to organize AWS resources, and cost allocation tags to track the AWS costs on a detailed level.
  • Upon cost allocation tags activation, AWS uses the cost allocation tags to organize the resource costs on the cost allocation report making it easier to categorize and track your AWS costs.
  • AWS provides two types of cost allocation tags,
    • an AWS-generated tag AWS defines, creates, and applies the AWS-generated tag for you,
    • and user-defined tags that you define, create,
  • Both types of tags must be activated separately before they can appear in Cost Explorer or on a cost allocation report

Alerts on Cost Limits

  • CloudWatch can be used to create billing alerts when the AWS costs exceed specified thresholds
  • When the usage exceeds threshold amounts, AWS sends an email notification

Consolidated Billing

AWS 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).
  • AWS services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
  • AWS exam questions are not updated to keep up the pace with AWS updates, so even if the underlying feature has changed the question might not be updated
  • Open to further feedback, discussion and correction.
