Concepts

Amazon Web Services (AWS) provides a rich set of tools for managing costs associated with cloud services, giving customers detailed insights into their usage patterns and the ability to control and optimize their spending. To help Solutions Architects and anyone preparing for the AWS Certified Solutions Architect – Associate (SAA-C03) exam understand these tools, we’ll delve into AWS Cost Explorer, AWS Budgets, and the AWS Cost and Usage Report, detailing their functionality and use cases.

AWS Cost Explorer

AWS Cost Explorer is a tool that enables users to visualize their AWS spending and usage patterns over time. With an intuitive interface, Cost Explorer allows users to analyze costs and usage with filtering and grouping capabilities.

Use Cases:

  • Identifying Trends: By analyzing the data from the past 13 months, a Solutions Architect can spot cost trends and use this information to forecast future costs.
  • Cost Breakdown: Allows for a detailed breakdown of costs by service, linked account, or usage type which can be particularly useful in a multi-department organization.
  • Reserved Instance Planning: By tracking RIs utilization and coverage, Cost Explorer helps in deciding whether to purchase additional RIs.

AWS Budgets

AWS Budgets assists users in setting budget thresholds and receiving alerts when costs or usage exceed preset budget amounts.

Use Cases:

  • Cost Control: A company can set a budget for their expected monthly AWS costs and be alerted if the cost is likely to exceed this budget.
  • Resource Usage: AWS Budgets can monitor the usage of specific AWS resources, which is useful for ensuring that resource utilization stays within an expected range.
  • Cost Allocation: Helps in tracking how costs are distributed across different projects or teams, ensuring that each is staying on budget.

AWS Cost and Usage Report

The AWS Cost and Usage Report (CUR) provides detailed information about the cost and usage associated with AWS services, delivering comprehensive data to the user’s Amazon S3 bucket.

Use Cases:

  • Detailed Cost Analysis: It provides line-item details on each service, enabling a deep dive into the exact costs.
  • Data Transfer Analysis: Organizations can analyze the data transfer costs which often have significant impact on the total bill.
  • Third-Party Integration: Data can be ingested by third-party tools for custom analysis, budgeting, and reporting.

Comparing the Tools

Feature Cost Explorer AWS Budgets Cost and Usage Report
Data Access Visual interface Alerts and budget thresholds Delivered to S3 bucket
Analysis Scope Up to 13 months of historical data Real-time monitoring Most detailed and historical data
Customization Limited to GUI options Can set custom alerts Highly customizable data sets
Data Delivery Immediate within the console Via email or SNS notifications Requires processing after delivery to S3
Suitable For Quick insights and trends Budget management and alerts Complex financial analysis or third-party use

Each of these tools serves distinct but complementary functions in managing AWS costs effectively. For example, a company could use AWS Budgets to set a spending cap on a monthly basis for their various projects. Then, they might use AWS Cost Explorer to drill down into individual services or departments to understand where and why they near or exceed those budgets. Afterwards, they could generate an AWS Cost and Usage Report to conduct a granular audit of every single resource and its associated costs over time, identifying optimization opportunities.

To further illustrate the use of these tools, let’s consider a hypothetical scenario. A Solutions Architect is tasked with managing the AWS costs for a multi-tier web application composed of Amazon EC2 instances, Amazon RDS databases, and various AWS Lambda functions.

  1. Using AWS Cost Explorer:

    They begin by using AWS Cost Explorer to visualize the costs associated with each tier of the application over the previous year. This helps them discover that the majority of the costs are coming from the EC2 instances, which could indicate suboptimal instance sizing or underutilization.

  2. Implementing AWS Budgets:

    Next, they configure AWS Budgets to receive alerts when the costs associated with the EC2 instances exceed a certain threshold, preventing unexpected spikes in spending.

  3. Deep Diving with AWS Cost and Usage Report:

    Finally, they download a detailed AWS Cost and Usage Report to analyze every aspect of the EC2 costs, discovering specific instances that generate disproportionate costs due to data transfer.

By using these tools in tandem, AWS customers have a multi-faceted approach to cost management that can lead to significant savings and more predictable cloud spending.

Answer the Questions in Comment Section

True or False: AWS Cost Explorer can only show past cost data and is not suitable for forecasting future costs.

  • (A) True
  • (B) False

Answer: B

Explanation: AWS Cost Explorer provides both historical and predictive features, allowing users to analyze and forecast costs for up to 12 months based on previous usage patterns.

True or False: AWS Budgets can be used to set custom budget alerts when your costs or usage exceed your predefined thresholds.

  • (A) True
  • (B) False

Answer: A

Explanation: AWS Budgets allows customers to set customized budget alerts that notify them via email or SNS when they exceed or are forecasted to exceed their budget thresholds.

Which AWS tool helps you to dive deeper into your cost and usage data at a granular level with the ability to access comprehensive billing information?

  • (A) AWS Cost Explorer
  • (B) AWS Budgets
  • (C) AWS Cost and Usage Report
  • (D) AWS Price List API

Answer: C

Explanation: AWS Cost and Usage Report contains the most comprehensive set of cost and usage data available, offering detailed insights for customers to understand their AWS spend.

True or False: AWS Budgets can be used to automatically adjust your service limits when the budget is reached.

  • (A) True
  • (B) False

Answer: B

Explanation: AWS Budgets can send alerts when you approach your budget limits, but it does not have the capability to automatically adjust service limits.

Which service or feature allows you to track your reserved instance (RI) and Savings Plans utilization and coverage?

  • (A) AWS Budgets
  • (B) AWS Cost Explorer RI Reports
  • (C) AWS Trusted Advisor
