AWS Cost Report

Use the AWS Cost report to analyze cost data found in your AWS Cost & Usage Report across all of your consolidated or linked AWS accounts. This report provides a breakdown of your costs for EC2, RDS, and S3 resources. The AWS Cost report is generated daily after initial setup.

This report is an ideal place to start your right sizing planning because it allows you to quickly understand your infrastructure spend on an operational level, such as identifying an over-reliance on On-Demand resources used for predictable, long-term workloads (more suited for reservations and savings plans) or those that might be less critical and time sensitive (more suited for Spot instances).

Each resource’s visualization supports quick toggling across relevant dimensions, such as:

• EC2: On-Demand, Savings Plan, and Data Transfer costs
• RDS: On-Demand and Storage
• S3: Put Requests, Get Requests, and Data Out

Cost Aggregation & Categories

Costs are aggregated, simplified, and reduced to the following categories element:

Type	Cost	Description
Hourly Instance Fees	On-Demand Instance	Hourly fee for an on-demand instance
Hourly Instance Fees	Spot Instance	Hourly fee for a spot instance
Hourly Instance Fees	Reserved Instance	Hourly fees for partial upfront or no-upfront reserved instances
Hourly Instance Fees	Amortized Upfront Reservation Fee	Amortized upfront fees for partial upfront or all-upfront instances **
Hourly Instance Fees	Dedicated Instance	Hourly fee for a dedicated instance
Hourly Instance Fees	Instance EBS Optimized Charge	Hourly incremental fee for EBS optimized instances (applies to certain instance types)
Hourly Instance Fees	Instance Dedicated Charge	Hourly incremental fee for dedicated host
Data Transfer Costs*	Data In – InterZone	Costs for data transfer to/from another AWS service in another availability zone or peered VPC in the same region
Data Transfer Costs*	Data In – InterRegion	Costs for data transfer to/from another AWS service in another region
Data Transfer Costs*	Data In – PublicIP	Costs for data transfer to/from another AWS service via a public or elastic IP address
Data Transfer Costs*	Data In – Internet	Costs for data transfer to/from the instance from/to the internet
Data Transfer Costs*	Data In – CloudFront	Costs for data transfer to/from the instance via CloudFront
Data Transfer Costs*	Other	Other data transfer costs (e.g., Direct Connect)

Configuration

Report configurations enable you to compare expensive instances against utilization, type, elements, and tags. You can also break down information like total versus individual instance costs or total instance state (Reserved, On-Demand) costs. Custom tagging is another easy way to group your instances.

1. Scope of Analysis

The following constraint options are available for EC2, RDS, and S3 reports:

• Name: A text-input that selects resources with that match any text provided, such as a prefix (e.g., west-app).
• Elements: A dropdown of all elements for manual selection with the option to select all.
• Attributes: A dropdown of all attributes for manual selection with the option to select all.
• Tags: A dropdown of all tags for manual selection with the option to select all.

2. Filters

Filters use operators and values to find resource with spend that meets certain conditions.

EC2

• Total Cost: Defines the total cost threshold applied to the operator.
• On-Demand Instance: Defines the total On-Demand cost threshold applied to the operator.
• On-Demand Instance (Savings Plan): Defines the total Savings Plan allocation threshold applied to the operator.
• Data Transfer: Defines the total Data Transfer cost threshold applied to the operator.
• Maximum CPU %: Defines the Maximum CPU % utilization applied to the operator.

RDS

• Total Cost: Defines the total cost threshold applied to the operator.
• On-Demand Instance: Defines the total On-Demand cost threshold applied to the operator.
• Storage: Defines the total storage cost threshold applied to the operator.
• Unknown: Defines the total unknown (not categorized by a standard operation) cost threshold applied to the operator.
• Maximum CPU %: Defines the Maximum CPU % utilization applied to the operator.

S3

• Total Cost: Defines the total cost threshold applied to the operator.
• Data Out: Defines the total Data Out cost threshold applied to the operator.
• Put Requests: Defines the total Put Request cost threshold applied to the operator.
• Get Requests: Defines the total Get Request cost threshold applied to the operator.
• Maximum Bucket Size (bytes): Defines the maximum Bucket Size applied to the operator.

3. Report Views

Report View & Grouping

Grouping options depend on the initial report view chosen. - Grouped by ID - Grouped by Element Name - Grouped by Attribute - Grouped by Tag - Grouped by Day - Grouped by Week - Grouped by Month - Grouped by Daily Run Rate

Utilization Metric & Metric Statistic

Each Utilization metric supports Mean, Maximum, 95th Percentile, Minimum, Total, and Count statistics. - EC2: Memory Utilization % - EC2 & RDS: CPU Utilization % - RDS: Disk Space Used % - RDS: Disk I/O % - S3: Bucket Size (bytes) - S3: Number of Objects - S3: Put Requests - S3: Get Requests

EC2 Considerations

EC2 elements without a CloudWatch Agent display only CPU Utilization %. If you have a mix of elements (some without a CloudWatch agent), you will see gaps in the utilization figures where values are not available.

Show

You can limit the results of your report by defining how many records to show.

Visualization

You can use this setting to disable the visualization if you wish to only use the results table.

Sorting

You can sort all of the follow columns by either ascending or descending.

• Total Cost
• Instance Type
• Maximum CPU %
• Elements
• On-Demand Instance
• Storage
• Unknown
