Difficulty: MediumAWS Cost Monitoring, Budgeting, and Optimization Tool Analysis

A company is experiencing unexpected cost increases across several AWS accounts. The finance team wants to implement a cost-governance strategy to receive alerts when monthly spending is projected to exceed their defined budget. Additionally, they want to automatically detect and receive notifications about sudden, unexpected cost spikes as close to real-time as possible. Which of the following actions should the Solutions Architect recommend to meet these requirements? (Select TWO)

  1. Create a custom budget in AWS Budgets, and configure an alert threshold based on forecasted costs to notify the team when projected spending exceeds the budget.Answer
  2. B
    Set up a daily scheduled report in AWS Cost Explorer to run every morning and trigger an Amazon SNS notification if the report indicates that the monthly budget has been exceeded.
  3. Configure AWS Cost Anomaly Detection with a cost monitor and subscribe to alerts using Amazon SNS to receive notifications when sudden, unexpected cost spikes occur.Answer
  4. D
    Enable AWS Billing Conductor to monitor real-time cost spikes at the account level and trigger automated Service Control Policies (SCPs) to terminate resources when costs exceed a threshold.
  5. E
    Create a CloudWatch billing alarm monitoring the EstimatedCharges metric with a 5-minute resolution to receive near real-time alerts on cost anomalies.

Answer

Creating a custom budget in AWS Budgets based on forecasted costs, and configuring AWS Cost Anomaly Detection with a cost monitor and alert subscription.
The correct combination involves configuring AWS Budgets to alert on forecasted cost overruns, which provides a proactive warning before the budget is exceeded, and setting up AWS Cost Anomaly Detection with a monitor and subscription to receive notifications of sudden cost spikes. These tools are built specifically for proactive, automated cost control and anomaly notification.

Step-by-Step Solution

1
Analyze the requirements for proactive cost monitoring and cost anomaly detection.
Identify that the system needs to alert on future budget overruns (forecasting) and sudden cost spikes (anomalies).
This establishes the functional requirements for selecting the appropriate AWS cost management tools.
2
Evaluate AWS Budgets for forecast-based alerting.
AWS Budgets can monitor costs against a threshold and send alerts based on forecasted spending, which meets the requirement of preventing budget overruns proactively.
Forecasted alerts allow organizations to take corrective action before a budget limit is actually breached.
3
Evaluate AWS Cost Anomaly Detection for sudden cost spikes.
AWS Cost Anomaly Detection uses machine learning to identify unexpected cost spikes and sends alerts via SNS, meeting the requirement for detecting anomalies.
Cost Explorer is retrospective and not designed for automated, near real-time anomaly alerting.

Key Concept

AWS Budgets and AWS Cost Anomaly Detection are designed for proactive cost alerting, whereas AWS Cost Explorer is intended for retrospective cost analysis and visualization.
