Set Up Cloud Cost Management for AWS

Updated 1 week ago by Archana Singh

Harness Cloud Cost Management (CCM) monitors and provides visibility into the cloud costs of your Amazon Web Services (AWS) across your cloud infrastructure and AWS services, such as EC2, S3, RDS, Lambda, and so on. CCM also allows you to optimize your instances, auto-scaling groups (ASGs), and EKS clusters using intelligent cloud AutoStopping rules.

You can set up CCM for your AWS resources, in a simple two-step process:

  1. Create a Cost and Usage Report (CUR). Harness CCM uses a secure, cross-account role with a restricted policy to access the cost and usage reports and resources for cost analysis.
  2. Create a Cloudformation stack to provision IAM Roles and corresponding policies to grant access for the required features. CCM offers the following features:

    Cost Visibility (Required)

    This feature is available by default and requires access to the CUR report. Provides the following capabilities:

    • Insights into AWS costs by services, accounts, etc.
    • Root cost analysis using cost perspectives
    • Cost anomaly detection
    • Governance using budgets and forecasts
    • Alert users using Email and Slack notification
      This feature will give you cost insights that are derived from the CUR. For deep Kubernetes visibility and rightsizing recommendations based on the historical utilization and usage metrics, set up Kubernetes connectors. See Set Up Cloud Cost Management for Kubernetes.

    AWS ECS and Resource Inventory Management (Optional)

    This feature provides visibility into your EC2, EBS volumes, and ECS costs. The insights provided by inventory management can be consumed by Finance teams to understand the resource utilization across the board.

    AWS resource optimization using AutoStopping rules (Optional)

    This feature allows you to enable Intelligent Cloud AutoStopping for your AWS instances and auto-scaling groups. For more information, see Create AutoStopping Rules for AWS.

    • Orchestrate VMs and ASGs based on idleness
    • Run your workloads on fully orchestrated spot instances
    • Provides Granular savings visibility

    Cloudformation template has policies corresponding to all the permissions (Visibility, Inventory, and Optimization). However, it is important to note that the permissions (policies) of the selected features will only be applied.
After enabling CCM, it takes about 24 hours for the data to be available for viewing and analysis.

Before You Begin

Review: AWS Connector Requirements

  • The same connector cannot be used in NextGen and FirstGen. For information on creating an AWS connector in the FirstGen see Set Up Cost Visibility for AWS.
  • For CCM, AWS connectors are available only at the Account level in Harness.
  • You can create multiple connectors per AWS account. See Create Multiple Connectors in an AWS Account.
  • Review the AWS connector requirements for different CCM features:
    • Cost Visibility: You can create an AWS connector for the master or linked account. CCM requires one connector per AWS account (master or linked) for cost visibility.
    • AWS ECS and Resource Inventory Management: You need to create an AWS connector for each linked account. For inventory management, CCM requires a connector for all the linked accounts.
    • AWS Resource Optimization Using AutoStopping Rules: You need to create an AWS connector for each linked account. For resource optimization using AutoStopping Rules, CCM requires a connector for all the linked accounts.

Review: Cost and Usage Reports (CUR) and CCM Requirements

  • If you have a consolidated billing process enabled, then CCM needs read-only access to the cost and usage reports (CUR) stored in the S3 bucket in the master or payer account. This gives access to the cost data for all the accounts (linked/member) in the organization.
  • If you don't have consolidated billing enabled at the organization level then you can create the CUR at a linked account level.
  • If you have provided CUR access to the master account then you do not need to provide billing details for each linked account. CCM requires one connector per AWS account (master or linked).

    It is recommended to create a CUR at the master account to avoid the CUR creation step for each linked account.
  • If you do not have access to the master account, you can create an AWS connector in the linked account for which you have the required access.
  • If you have created a billing report for your AWS account ID once then you can use the same CUR again for the AWS connector. You do not need to create CUR again for the same account.

Review: AWS Access Permissions

CCM requires the following permissions:

If you don't have access to create a cost and usage report or run a CloudFormation template, contact your IT or security teams to provide the required permissions.

Step 3: Select Features

Select the Cloud Cost Management features that you would like to use on your AWS account. Based on your selection Harness requires specific permissions for the cross-account role. See Review: AWS Access Permissions.

CCM offers the following features:

Cost Visibility (Required)

This feature is available by default and requires access to the CUR report. Provides the following capabilities:

  • Insights into AWS costs by services, accounts, etc.
  • Root cost analysis using cost perspectives
  • Cost anomaly detection
  • Governance using budgets and forecasts
  • Alert users using Email and Slack notification

This feature will give you cost insights that are derived from the CUR. For deep Kubernetes visibility and rightsizing recommendations based on the historical utilization and usage metrics, set up Kubernetes connectors. See Set Up Cloud Cost Management for Kubernetes.

AWS ECS and Resource Inventory Management (Optional)

This feature provides visibility into your EC2, EBS volumes, and ECS costs. The insights provided by inventory management can be consumed by Finance teams to understand the resource utilization across the board.

AWS resource optimization using AutoStopping rules (Optional)

This feature allows you to enable Intelligent Cloud AutoStopping for your AWS instances and auto-scaling groups. For more information, see Create AutoStopping Rules for AWS.

  • Orchestrate VMs and ASGs based on idleness
  • Run your workloads on fully orchestrated spot instances
  • Granular savings visibility

Make your selection and click Continue.

Step 4: Create Cross-Account Role

Harness uses the secure cross-account role to access your AWS account. The role includes a restricted policy to access the cost and usage reports and resources for the sole purpose of cost analysis and cost optimization.

  1. In Create Cross Account Role, click Launch Template in AWS console.
  2. In Quick create stack, in Capabilities, select the acknowledgment, and click Create stack.
    It is recommended that you do not modify any value in the Quick create stack page.


    The value for BillingEnabled, EventsEnabled, and OptimizationEnabled varies depending on the features that you have selected in the Select Features step.
  3. In the Stacks page, from the Outputs tab copy the Value of CrossAccountRoleArn Key.
  4. In Role ARN, enter the Cross-Account Role ARN that you copied from the Outputs tab (previous step) in Harness.
  5. The External ID is generated dynamically for your account. For example, harness:111111111111:lnFZRF6jQO6tQnB9xxXXXx .
    Do not modify the value of External ID.
  6. Click Save and Continue.

Step 5: Test Connection

The validation and verification happen in this step. Once the validation and verification are completed, click Finish.

Your connector is now listed in the Connectors.

Step: Create Multiple Connectors in an AWS Account

Harness CCM also provides the flexibility to create multiple Connectors using a stack set configured at the master account level. It involves the following steps:

  • Create a stack set
  • Create an API Key in Harness
  • Add an Admin Role
  • Run the cURL Command to create connectors using the Roles created in the AWS accounts via API

Step 1: Create a Stack Set in AWS

Perform the following steps to create a stack set in AWS:

  1. Launch create stack set template using the following link:
    https://console.aws.amazon.com/cloudformation/home?region=us-east-1#/stacksets/create
  2. In Choose a template, in Permissions, select Service-managed permissions.
  3. In Prerequisite - Prepare template, select Template is ready.
  4. In the Specify template, in the Template source, select Amazon S3 URL.
  5. In the Amazon S3 URL enter the following URL and click Next.
    https://continuous-efficiency-prod.s3.us-east-2.amazonaws.com/setup/ngv1/HarnessAWSTemplate.yaml
  6. In Specify StackSet details, in StackSet name, enter a stack set name. For example, harness-ce-iam-stackset.
  7. In Parameters, specify the following details:
    1. Set BillingEnabled to false.
    2. Leave the BucketName empty.
    3. Set EventsEnabled to true.
    4.  In ExternalID enter your <Harness Account ID>, for example, harness:111122225555 .
    5. In LambdaExecutionRoleName, enter Lambda execution role name, for example, HarnessCELambdaExecutionRole. The Lambda execution role name must begin with Harness.
    6. Set OptimizationEnabled to true.
    7. PrincipalBilling is auto-generated for your AWS account. Do not edit the Principal Billing details. For example, arn:aws:iam::123451231355:root.
    8. In RoleName, enter the role name, for example, HarnessCERole. The role name must begin with Harness e.g., HarnessCERole, HarnessManagedRole.
  8. Once you've entered all the details, click Next.
  9. In Configure StackSet options, in Managed execution, select Active and click Next.
  10. In Set deployment options, in Add stacks to stack set, select Deploy new stacks.
  11. In Deployment targets, select Deploy to organization (recommended). You can select Deploy to Organizational Units (OUs) to limit the monitoring clusters to a particular OU or a subset of linked accounts.
  12. In Automatic deployment, select Enabled.
  13. In Account removal behavior, select Delete Stacks.
  14. Select a region from the drop-down list and click Next.
  15. In Deployment Options, in Region Concurrency, select Sequential.
  16. Review the details, select acknowledgment, and click Submit.

Step 2: Create an API Key in Harness

  1. In Harness, click Home.
  2. In Account Setup, click Access Control.

  4. In the Service Account's settings page, click API Key.
  5. In the New API Key settings, enter Name, Description, and Tags.
  6. Click Save. The new API Key is created.

    Once you've created an API Key for your Service Account, generate a Token for this API Key.
  7. To generate a Token for this API Key, click Token below the API Key you just created.
    1. In the New Token settings, enter Name, Description, and Tags.
    2. To set an expiration date for this token, select Set Expiration Date.
    3. Enter date in Expiration Date (mm/dd/yyyy).
    4. Click Generate Token.
    5. Your new Token is generated.
    You cannot see this token value after you close this dialog. Make sure to copy and store the generated token value securely.

You need to enter this Token when running your cURL command.

Step 3: Add an Admin Role to the Service Account

Ensure that you've added the Admin role to this Service Account. For more information, see Add and Manage Roles.

Step 4: Run the cURL Command

Run the following command for each AWS Account ID and IAM Role Pair:

curl -i -X POST \
