Architecture

FinOps Center is 100% Cloud-Native leveraging a number of AWS Services. The Full Architecture runs Across Multiple AWS Account Aligned to the Multi-Acccount Strategy.

In the Master Payer Account - FinOps Center leverages the Cost & Usage Report (CUR) for Billing information. The CUR is stored in a s3 Bucket in the Master Payer Account. Customers leverage AWS Bucket Replication (and Batch Operations) to move the CUR Objects to the S3 bucketing in the FinOps Center Installed Account.

One of the limitations of the CUR is the delay in Accounts showing up on the file. During the Account Vending Process, this delay will add work to align AWS Accounts to Financial Budgets. To facilitate this end-to-end process, FinOps Center (in the Delegated Admin / CloudOps Account) queries the Organization/Account Management API to immediately make Accounts onboarded even prior to the Account having billing.
