Effective August 1, 2019, pricing for AWS Config rules will be changing. For more details, see Upcoming changes to AWS Config rules.  

With AWS Config, you are charged based on the number of configuration items recorded and the number of active AWS Config rules in your account. A configuration item is a record of the configuration of a resource, in your AWS account. There is no up-front commitment and you can stop recording configuration items at any time. An AWS Config rule is considered active during a month if it records a compliance result against at least one resource during a particular month.

Pricing details

You can choose to evaluate rules when AWS resources change, or at periodic intervals like hourly or daily. The cost per rule per account in a month is the same regardless of how many times the rule is evaluated or how many resources the rule evaluates. You pay only for active rules in a given month, not for the total rules in your accounts.

Additional costs

Configuration snapshots and configuration history files are delivered to you in the Amazon S3 bucket that you choose, and configuration change notifications are delivered via Amazon Simple Notification Service (SNS). Standard rates for Amazon S3 and Amazon SNS apply. Custom rules are authored using AWS Lambda. Standard rates for AWS Lambda apply. For remediation with AWS Config rules, limits and rates for AWS Systems Manager Automation apply.

Except as otherwise noted, our prices are exclusive of applicable taxes and duties, including VAT, GST and applicable sales tax.

Upcoming changes to AWS Config rules pricing (Effective August 1, 2019)

Effective August 1, 2019, you will be charged based on the number of AWS Config rules evaluations recorded, instead of the number of active rules in your account per region. This new pricing is designed to provide almost all current AWS Config rules customers with a significant reduction in Config rules cost. A rule evaluation is recorded every time an AWS Config rule is evaluated against a resource. Pricing for AWS Config rule evaluations will be as follows in AWS Public Regions:

    First 100K rule evaluations at $0.001 per rule evaluation per region;
    Next 400K (100,001 – 500,000) rule evaluations at $0.0008 per rule evaluation per region;
    500,001 rule evaluations and more at $0.0005 per rule evaluation per region.

In AWS GovCloud regions, the following pricing will apply for AWS Config rule evaluations:

    First 100K rule evaluations at $0.0012 per rule evaluation per region;
    Next 400K (100,001 – 500,000) rule evaluations at $0.00096 per rule evaluation per region;
    500,001 rule evaluations and more at $0.0006 per rule evaluation per region.

With consolidated billing, AWS will measure the combined number of AWS Config rules evaluations from all of your accounts to determine which pricing tier applies, giving you a lower overall price whenever possible. Your accounts will automatically be enrolled in the new pricing plan starting August 1, 2019. Additional costs shown above, including charges for configuration items, will continue to apply.
 

Pricing example

Let’s assume you have the following usage in US East (N.Virginia) Region in a given month.
10,000 Configuration items recorded across various resource types
100 Config rules- with 60 active rules in the month.
    50 Config rules that invoked 500 rule evaluations each
    9 Config rules that invoked 1000 rule evaluations each
    1 Config rule that invoked 10,000 rule evaluations

 

Cost under current model

Cost under the new model

(effective August 1, 2019)

Cost of configuration items

10,000 * $0.003 = $30

10,000 * $0.003 = $30

Cost of Config rules

60 active rules with tiered pricing

First 10 rules at $2.00 each = 10* $2.00 = $20

Next 40 rules at $1.50 each = 40 * $1.50 = $60

50 rules and more at $1 each = 10 * $1 = $10

Total Config rules cost = $90

50 Config rules that invoked 500 rule evaluations each = 50*500 = 25,000 evaluations.

9 Config rules that invoked 1000 rule evaluations each= 9 *1000 = 9,000 evaluations

1 Config rule that invoked 10,000 rule evaluations

Total evaluations = 25,000 + 9,000 + 10,000= 44,000

First 100,000 evaluations at $0.001 each = $44

Total Config Bill

$30 + $90 =$120

$30 + $44 = $74
