Overview
Cloud Cost Management provides insights for engineering and finance teams to see how changes to infrastructure can affect costs. It enables you to understand trends, allocate spend across your organization, and identify inefficiencies.
Datadog ingests your cloud cost data and transforms it into queryable metrics. If costs rise, you can correlate the change with usage metrics to determine the root cause.
Setup
To use AWS Cloud Cost Management, you must have an AWS account with access to Cost and Usage Reports (CURs), and have the AWS integration installed in Datadog. To set up Cloud Cost Management in Datadog, you need to generate a Cost and Usage report.
Prerequisite: generate a Cost and Usage Report
Follow AWS instructions for Creating Cost and Usage Reports, and select the following content options for use with Datadog Cloud Cost Management:
Include resource IDs
Check the box for “Automatically refresh your Cost & Usage Report when charges are detected for previous months with closed bills.”
Select the following Delivery options:
Time granularity: Hourly
Report versioning: Create new report version
Compression type: GZIP or Parquet
Format: text/csv or Parquet
Configure the AWS integration
Navigate to Setup & Configuration and select an AWS account from the dropdown menu to pull costs from.
Note: Datadog recommends sending a Cost and Usage Report from an AWS management account for cost visibility into related member accounts. If you send a Cost and Usage report from an AWS member account, ensure that you have selected the following options in your management account’spreferences:
Linked Account Access
Linked Account Refunds and Credits
Linked Account Discounts
This ensures complete cost accuracy by allowing periodic cost calculations against the AWS Cost Explorer.
Locate the Cost and Usage Report
If you have navigated away from the report that you created in the setup prerequisites section, follow AWS documentation to find and view your Cost and Usage Reports details.
To enable Datadog to locate the Cost and Usage Report, complete the fields with their corresponding details:
Region: This is the region your bucket is located. For example, us-east-1.
Bucket Name: This is the name of the s3 bucket that the CUR is saved to.
Report Path Prefix: This is the folder name. If viewing Report path prefix from the AWS details page, this is the first section of the path. For example, if Report path prefix is displayed as cur-report-dir/cost-report, you would enter cur-report-dir.
Report Name: This is the name you entered when you generated the report in the prerequisite section. If viewing the Report path prefix from the AWS details page, this is the second half of the path. For example, if Report path prefix is displayed as cur-report-dir/cost-report, you would enter cost-report.
Configure access to the Cost and Usage Report
Configure AWS to ensure Datadog has permissions to access the CUR and the s3 bucket it is stored in by creating a policy using the following JSON:
Tip: Make note of the name you created for this policy for next steps.
Attach the policy to the Datadog integration role
Attach the new S3 policy to the Datadog integration role.
Navigate to Roles in the AWS IAM console.
Locate the role used by the Datadog integration. By default it is named DatadogIntegrationRole, but the name may vary if your organization has renamed it. Click the role name to open the role summary page.
Click Attach policies.
Enter the name of the S3 bucket policy created above.
Click Attach policy.
Note: Data can take up to 48 to 72 hours after setup to stabilize in Datadog.
Cost types
You can visualize your ingested data using the following cost types:
Cost Type
Description
aws.cost.amortized
Cost based on applied discount rates plus the distribution of pre-payments across usage for the discount term (accrual basis).
aws.cost.unblended
Cost shown as the amount charged at the time of usage (cash basis).
aws.cost.blended
Cost based on the average rate paid for a usage type across an organization’s member accounts.
aws.cost.ondemand
Cost based on the list rate provided by AWS.
Tag enrichment
Datadog adds out-of-the-box tags to the ingested cost data to help you further break down and allocate your costs. These tags are derived from your Cost and Usage Report (CUR).
The following out-of-the-box tags are also available for filtering and grouping data:
Tag
Description
aws_product
The AWS service being billed.
aws_product_family
The category for the AWS service being billed (for example, Compute or Storage).
aws_management_account_name
The AWS management account name associated with the item.
aws_management_account_id
The AWS management account ID associated with the item.
aws_member_account_name
The AWS member account name associated with the item.
aws_member_account_id
The AWS member account ID associated with the item.
aws_cost_type
The type of charge covered by this item (for example, Usage, or Tax).
aws_pricing_term
Whether the usage is Reserved, Spot, or On-Demand.
aws_reservation_arn
The ARN of the Reserved Instance that the item benefited from.
aws_savings_plan_arn
The ARN of the Savings Plan the item benefited from.
aws_usage_type
The usage details of the item (for example, BoxUsage:i3.8xlarge).
aws_operation
The operation associated with the item (for example, RunInstances).
aws_region
The region associated with the item.
aws_availability_zone
The availability zone associated with the item.
aws_resource_id
The resource ID associated with the item.
aws_instance_type
The instance types associated with your items.
aws_instance_family
The instance family associated with your item (for example, Storage optimized).
is_aws_ec2_compute
Whether the usage is related to EC2 compute.
is_aws_ec2_compute_on_demand
Whether the usage is on-demand.
is_aws_ec2_compute_reservation
Whether the usage is associated with a Reserved Instance.
is_aws_ec2_capacity_reservation
Whether the usage is associated with a Capacity Reservation.
is_aws_ec2_spot_instance
Whether the usage is associated with a Spot Instance.
is_aws_ec2_savings_plan
Whether the usage is associated with a Savings Plan.
Billing conductor
Billing conductor enables you to simplify your bill by customizing the billing rates, distributing credits and fees, and sharing overhead costs at your discretion. You can also select which accounts to include in the CUR.
To create a billing conductor CUR, follow the AWS Cost and Usage Reports user guide. Ensure the CUR meets Datadog’s requirements.
After the billing conductor CUR is created, follow the Cloud Cost Management instructions above to set it up in Datadog.
To use Azure Cloud Cost Management in Datadog, you must set up the Datadog Azure integration and set up amortized and actual exports. Additionally, Datadog must have permissions to read the exports from the container.
Notes:
If you are using Datadog’s US3 site, you may have set up the Datadog Azure Native integration using the recommended Datadog Resource method through the Azure Portal. To support Cloud Cost Management, you need to create an App Registration.
Microsoft Customer Agreement exports must be configured at the subscription level. If you have an Enterprise plan, you can configure your billing accounts to onboard all subscriptions.
Pay-as-you-go accounts are not supported.
Generate cost exports
Navigate to Exports under Azure portal’s Cost Management + Billing.
Select the export scope. Note: The scope must be billing account, subscription, or resource group.
After the scope is selected, click Add.
Select the following Export details:
Metric: Actual Cost (usage and purchases)
Export type: Daily export of month-to-date costs
File Partitioning: On
Choose a storage account, container, and directory for the exports. Note: Billing exports can be stored in any subscription. If you are creating exports for multiple subscriptions, Datadog recommends storing them in the same storage account. Export names must be unique.
Select Create.
Repeat steps one to six for Metric: Amortized Cost (usage and purchases). Datadog recommends using the same storage container for both exports. For faster processing, generate the first exports manually by clicking Run Now.
Provide Datadog access to your exports
In the Exports tab, click on the export’s Storage Account to navigate to it.
Click the Containers tab.
Choose the storage container your bills are in.
Select the Access Control (IAM) tab, and click Add.
Choose Add role assignment.
Choose Storage Blob Data Reader, then click Next.
Assign these permissions to one of the App Registrations you have connected with Datadog.
Click Select members, pick the name of the App Registration, and click Select.
Select review + assign.
If your exports are in different storage containers, repeat steps one to seven for the other storage container.
Configure Cost Management Reader access
Note: You do not need to configure this access if your scope is Billing Account.
Navigate to your subscriptions and click your subscription’s name.
Select the Access Control (IAM) tab.
Click Add, then Add role assignment.
Choose Cost Management Reader, then click Next.
Assign these permissions to the app registration.
This ensures complete cost accuracy by allowing periodic cost calculations against Microsoft Cost Management.
You can visualize your ingested data using the following cost types:
Cost Type
Description
azure.cost.amortized
Cost based on applied discount rates plus the distribution of pre-payments across usage for the discount term (accrual basis).
azure.cost.actual
Cost shown as the amount charged at the time of usage (cash basis). Actual costs include private discounts as well as discounts from reserved instances and savings plans as separate charge types.
Cloud costs in dashboards
Visualizing infrastructure spend alongside related utilization metrics can help you spot potential inefficiencies and savings opportunities. You can add cloud costs to widgets in Datadog dashboards by selecting the Cloud Cost data source.
