Difficulty: EasyAWS Cost Explorer and Cost Anomaly Detection

A SysOps administrator needs to configure a system to monitor AWS account spending and send alerts whenever there is a sudden, unexpected spike in cost. The spending patterns are variable and unpredictable, making static thresholds ineffective. The administrator wants a solution that uses machine learning to dynamically detect these cost anomalies. Which AWS feature should the administrator use to achieve this goal?

  1. AWS Cost Anomaly DetectionAnswer
  2. B
    AWS Budgets
  3. C
    Amazon EventBridge rules
  4. D
    AWS Cost Allocation Tags

Answer

AWS Cost Anomaly Detection
AWS Cost Anomaly Detection is the only listed feature that uses machine learning to analyze spending data, identify abnormal spikes, and alert administrators without requiring the manual configuration of static thresholds.

Step-by-Step Solution

1
Analyze the requirements to find a tool that detects sudden cost spikes in variable and unpredictable spend patterns.
Determined that static limits will not work, meaning a machine learning-driven dynamic threshold is needed.
Variable and unpredictable spending patterns make manual thresholds prone to false positives or false negatives.
2
Evaluate the capabilities of the correct service, AWS Cost Anomaly Detection.
AWS Cost Anomaly Detection matches the requirement by dynamically baseline-learning spending patterns using machine learning models.
It detects anomalies and alerts administrators dynamically, satisfying the specific project request.
3
Contrast AWS Cost Anomaly Detection with static budgeting and configuration features.
AWS Budgets requires static limits, EventBridge routes events, and Cost Allocation Tags categorize costs.
This rules out the incorrect options.

Key Concept

AWS Cost Anomaly Detection utilizes machine learning models to establish dynamic baselines and alert on unexpected cost spikes, making it ideal for variable spending patterns where static budgets are ineffective.
