Difficulty: EasyAWS Budgets and Cost Alerts

A SysOps administrator wants to configure cost alerts for a development sandbox account. The administrator needs to receive an email notification as soon as the monthly spend for the account is projected to exceed $500, before the actual charges are incurred.

Which AWS service or feature should the administrator use to meet this requirement?

  1. An AWS Budgets cost budget with an alert threshold based on forecasted costAnswer
  2. B
    An AWS Cost Anomaly Detection monitor with a threshold of $500
  3. C
    An Amazon CloudWatch billing alarm configured with detailed monitoring enabled
  4. D
    Cost allocation tags activated in the Billing console with billing alerts enabled

Answer

An AWS Budgets cost budget with an alert threshold based on forecasted cost
An AWS Budgets cost budget is the correct solution because it allows administrators to create alerts that trigger based on forecasted costs. This satisfies the requirement of notifying the administrator when the projected monthly spend is predicted to exceed the threshold ($500) before those costs are actually incurred.

Step-by-Step Solution

1
Identify the requirement to trigger an alert based on forecasted monthly spend before the threshold is actually exceeded.
Determined that the solution must support forecasting capabilities.
Traditional billing alarms only trigger on actual accumulated costs, which does not satisfy the requirement to alert before the charges are incurred.
2
Evaluate AWS native services that support forecast-based alerting.
AWS Budgets is identified as the service designed to track costs against a threshold and generate alerts based on actual or forecasted amounts.
AWS Budgets allows setting up alerts when forecasted monthly spend is projected to exceed the budget limit ($500).
