AWS Cost Management Tools - Native Integration of Cost Explorer, Budgets, and Compute Optimizer
AWS natively integrates cost management tools such as Cost Explorer, Budgets, Compute Optimizer, and Trusted Advisor. We analyze the advantages of AWS's cost visibility and optimization compared to Azure Cost Management and GCP's billing management.
Overview of AWS Cost Management Tools
AWS provides multiple native tools for cost management, each serving a different role while functioning as an integrated whole. Cost Explorer is a cost and usage visualization and analysis tool that lets you filter and analyze trends across the past 13 months of data from multiple angles. Budgets handles budget setting and alert notifications, offering budget types for cost, usage, RI utilization and coverage, and Savings Plans utilization and coverage. Compute Optimizer uses machine learning to analyze EC2, EBS, and Lambda resource sizes and provides instance type recommendations. Trusted Advisor runs best practice checks across five categories including cost optimization. These tools work together within the AWS Management Console, so you can carry out cost management without third-party tools.
The Analytical Power of Cost Explorer
Cost Explorer is the core tool for AWS cost analysis. It can break down costs by various dimensions such as service, region, account, and tags, and visualize trends at daily and monthly granularity. One of its main features is RI and Savings Plans recommendations, which automatically show purchase options and estimated savings based on past usage patterns. Cost Anomaly Detection uses machine learning to detect cost anomalies and help you spot unexpected spending increases. Data retrieval via API is also available, which supports integration with internal dashboards and BI tools. Azure Cost Management offers similar analytical capabilities. GCP's billing reports have the strength of flexible analysis through BigQuery export, and AWS builds its analysis features into the console.
Budgets and Automated Actions
AWS Budgets goes beyond simple alert notifications by enabling automated actions when budgets are exceeded. With Budget Actions, you can automatically apply IAM policies, attach SCPs, or stop EC2 and RDS instances when budget thresholds are crossed. With this, actions proceed without waiting for a manual response, although AWS Budgets information is updated up to three times a day and notifications sometimes arrive after a delay from when a charge is incurred. Up to 2 budgets can be created for free, making it easy to start cost management even in small environments. Azure Budgets also provides alert notifications and automation through Action Groups, but forceful actions like directly stopping resources require combining with Azure Policy. GCP's budget alerts typically trigger Cloud Functions via Pub/Sub, and automated actions aren't built into the budget feature itself, requiring custom implementation.
The Synergy of Compute Optimizer and Trusted Advisor
Compute Optimizer analyzes CloudWatch metrics with machine learning and provides resource sizing optimization recommendations for EC2 instances, Auto Scaling groups, EBS volumes, and Lambda functions. It identifies over-provisioned resources and presents specific cost savings from downsizing. It also includes recommendations for migrating to Graviton instances. Trusted Advisor runs checks across five categories - cost optimization, security, fault tolerance, performance, and service limits - detecting unused Elastic IPs, underutilized EC2 instances, unused EBS volumes, and more. Azure Advisor offers similar recommendation features, and on AWS, Compute Optimizer analyzes sizing with machine learning.
Cost Management in Multi-Account Environments
In multi-account environments using AWS Organizations, the integration of cost management tools is useful. Consolidated Billing aggregates usage across the entire organization to make use of RI and Savings Plans discounts. Cost Explorer can break down organization-wide costs by account, visualizing cost allocation for each team or project. With cost allocation tags, you can track costs at the project level across accounts.
Summary
AWS's cost management tool suite combines visualization (Cost Explorer), budget management (Budgets), resource optimization (Compute Optimizer), and best practice checks (Trusted Advisor). Beyond each tool functioning independently, they also support multi-account environments through Organizations integration, and can be used for cost management in large organizations without third-party tools. Azure and GCP individually offer equivalent features, and AWS provides integration between these tools and automated budget actions.
