Financial Budget to Cloud Allocation
FinOps Center is designed to have 2 tiers of allocation to a Financial Budg
Cloud allocation maps financial budgets to AWS infrastructure through a percentage-based distribution model. Budget flows from accounts to workloads to individual resources, with each resource either "claimed" (100% allocated to one workload) or "open/shared" (distributed by allocation percentage). The Financial Admin manages account allocation percentages, Product Owners claim resources for their workloads, and Cloud Engineers claim resources on behalf of Product Owners. Claimed resources show their full cost against the claiming workload, while shared cost is calculated as unblended cost multiplied by allocation percentage. The system tracks five discount types and net_cost calculations on a daily basis.
Account Allocation: Aligned to the multi-account framework, AWS Account Billing is split by percentage allocation to a budget. The Allocation begins to either the Vending date of the Account or the 1st of the Previous Month. Allocation can be updated to the beinning of Period (aka weekly). All resources will be allocated to that budget at the % rate.
Workload Allocation: Product Owners create estimates for Workload. Workload can then "Claim" resources to them by Admin, Financial Admins, or the Product owners that will then have 100% allocation to that budget as of the next day from Claiming.
As detailed below - Spending is then discounted (if applicable) and reduced by available Credits at the budget level.
