Overview

The AWS Billing server provides comprehensive cost management and optimization capabilities for AWS accounts, enabling you to track spending, analyze cost trends, detect anomalies, and identify optimization opportunities across your cloud infrastructure.

​
How to Add AWS Billing

1

Create IAM User

  1. Log in to your AWS Console
  2. Navigate to IAM > Users
  3. Create a new user with programmatic access
2

Attach Required Policies

Attach the following AWS managed policies to the IAM user:
  • ViewOnlyAccess or AWSBillingReadOnlyAccess (core billing)
  • CostOptimizationHubReadOnlyAccess (must enable in us-east-1)
  • ComputeOptimizerReadOnlyAccess (requires opt-in)
  • AWSBudgetsReadOnlyAccess (budget status)
3

Generate Access Keys

  1. Select the user and go to Security credentials
  2. Create an access key for programmatic access
  3. Save your Access Key ID and Secret Access Key
4

Connect to Nexus

  1. Add the AWS Billing server to your Nexus environment
  2. Enter your AWS credentials when prompted
Enable Cost Optimization Hub in us-east-1 region and opt into Compute Optimizer. It takes approximately 12 hours for initial data to populate.

Date Formats: Use ISO format (YYYY-MM-DD) for dates. End dates are exclusive.Granularity: Daily granularity works best for periods under 3 months; use monthly for longer periods.Metrics: UnblendedCost is the default and recommended metric for most cost queries.Cost Optimization Hub: Available only in us-east-1 region.Data Freshness: Cost data typically has a 24-48 hour delay.
Storage Lens: Currently not supported. Requires S3 Storage Lens configuration.Resource-level data: Limited to last 14 days for detailed resource queries.Budgets: Cannot create or modify budgets, only view existing ones.
