Prerequisites for CCI

Ensure the consolidated billing is set up for AWS Organizations. This consolidates billing across all accounts in your organization for unified cost management.

AWS Cost and Usage Reports (CUR) will be stored in an S3 bucket. We recommend the S3 bucket to be created in the us-east-2 region. Follow these steps to create a dedicated bucket:

1. Sign in to the AWS Management Console.

2. Navigate to S3 service.

3. Click Create bucket.

4. Enter a unique bucket name (e.g <your-company-name>-billing).

5. Configure bucket settings:

   • Enable versioning
   • Disable public access (recommended)
   • Enable default encryption (recommended)

6. Tags (Optional): Add any tags if needed for your organization's resource management.

7. Click Create bucket.

   Importante

   Remember the bucket name as you'll need them in the following steps and installation steps on CCI.

Create a Cost and Usage Report to be delivered to your S3 bucket:

1. Sign in to the AWS Management Console.

2. Navigate to the Billing Dashboard.

3. In the left navigation pane, click Cost & Usage Analysis.

4. Click Data Exports and then Create.

5. Configure report settings:

   Setting	Value	Description
   Export Type	Standard Data Export	Provides detailed information about usage and costs, suitable for most billing and cost analysis use cases.
   Export Name	Name	Export name that provides context to the CUR report. (eg-<company name-billing-cci>)>
   Data Table	CUR 2.0	CUR 2.0 supports the latest FOCUS format table structure.
   Include Resource IDs	ON	Enables detailed tracking of costs associated with individual AWS resources, aiding in fine-grained analysis and billing.
   Split Cost Allocation Data	OFF	If not specifically needed, keeping this option off simplifies the data structure. It avoids separating data based on custom cost categories or splits. This might be left off unless detailed cost allocation splits are necessary for your analysis.
   Time granularity	Hourly	Sets the time granularity to hourly. This setting is essential for enabling detailed cost and usage analysis, which supports the platform's functionality.
   Compression type	Parquet	A columnar storage file format that enhances query performance and reduces storage space, beneficial for processing large data volumes efficiently.
   File Versioning	Create New Report Version	Each update to the CUR creates a new version. This retains historical reports, which are useful for auditing and tracking cost changes over time.
   Data Refresh Settings	AUTOMATIC	Ensures that CUR data is kept up-to-date with the latest usage and cost information without manual intervention.
   Data Export Setting S3 Bucket	Existing (Select the bucket created in Step 1)	The CUR file created would be saved in the S3 bucket with a defined path described below. Agree to overwrite the policy (we would map the policy with a new one in next step)
   S3 path prefix	cost-and-usage-reports	Ensures that your Cost and Usage Reports (CUR) are organized and stored correctly within the S3 bucket, facilitating efficient access and management.

6. Click Next and then Create report.

   Importante

   Remember the export name as you'll need them in the integration step on CCI. Also, validate the S3 path prefix to be cost-and-usage-reports.

   Note

   The first CUR report will be delivered within 24 hours. Subsequent reports are delivered on a periodic basis.

Create an IAM policy that grants CCI the necessary permissions to access your CUR data:

1. Sign in to AWS Management Console.

2. Navigate to IAM service.

3. Click Policies in the left navigation pane.

4. Click Create policy.

5. Switch to the JSON editor and paste the following policy:

   {
     "Version": "2012-10-17",
     "Statement": [
       {
         "Action": ["s3:Get*", "s3:List*"],
         "Effect": "Allow",
         "Resource": [
           "arn:aws:s3:::<bucket-name>/*",
           "arn:aws:s3:::<bucket-name>"
         ],
         "Sid": "AccessMasterPayerBillingBucket"
       },
       {
         "Effect": "Allow",
         "Action": [
           "pricing:DescribeServices",
           "pricing:GetAttributeValues",
           "pricing:GetProducts",
           "pricing:GetPriceListFileUrl",
           "pricing:ListPriceLists"
         ],
         "Resource": ["*"]
       }
     ]
   }

   Importante

   Replace bucket-name with the actual name of the S3 bucket you created in S3 bucket for Cost and Usage reports step.

6. Click Next.

7. Name the policy CCI-Access-Policy (or your preferred name).

8. Add a description.

9. Click Create policy.

Create an IAM role that CCI will assume to access your CUR data:

1. Sign in to AWS Management Console.

2. Navigate to IAM service.

3. Click Roles in the left navigation panel.

4. Click Create role.

5. Select Custom Trust Policy in the trusted entity type section.

6. Paste the following role definition in the editor:

   {
     "Version": "2012-10-17",
     "Statement": [
       {
         "Effect": "Allow",
         "Principal": {
           "AWS": "arn:aws:iam::207192125115:user/cci_global_user"
         },
         "Action": "sts:AssumeRole",
         "Condition": {
           "StringEquals": {
             "sts:ExternalId": "<externalID>"
           }
         }
       }
     ]
   }

   Note

   The externalId is a dynamic unique identifier of CCI integration service, it’s generated once we move back to CCI to start the integration.

7. Click Next.

8. Attach the policy created in IAM policy for CCI access step.

9. Click Next.

10. Role name: CCI-Access-Role (or your preferred name).

11. Add a description (optional).

12. Click Create role.

13. After role creation, note the Role ARN (displayed on the role summary page).

    Importante

    You'll need to provide the Role ARN to CCI during the integration process.
