Onboarding/Modifing Financial Budget
Creation of Approved AWS Spending by Budget
Overview
Financial Budget Onboarding is the foundational process in FinOps Center's Cloud Financial Management framework. It establishes the four-level budget hierarchy (E1 through E4) that organizes all cloud spending, creates budget entries at each level, configures cost allocation percentages, and maps budgets to specific AWS accounts. Every other CFM process depends on this initial budget structure being in place.
Process Steps
1. Define the Budget Hierarchy - Establish the four-level financial element structure: Business Unit (E1), Department (E2), Portfolio (E3), and Product (E4). This hierarchy determines how costs roll up and how financial data is scoped for each role.
2. Create Budget Entries - Add budget line items at the appropriate hierarchy level. Budgets can be set on monthly or annual periods and support multiple fiscal years (2024, 2025, 2026). Each entry tracks both estimated and approved amounts.
3. Set Allocation Percentages - Configure what portion of each budget maps to AWS accounts. These percentages drive the cost allocation model: resources are either claimed (100% allocated to one workload) or open/shared (cost distributed by allocation percentage).
4. Assign to AWS Accounts - Link budget entries to specific AWS account IDs. Account names are resolved from the account_mapping table. Once assigned, cost tracking activates and QuickSight dashboards begin populating with spend data.
Key Concepts
Budget Hierarchy (E1-E4): Business Unit, Department, Portfolio, Product. Each level scopes financial visibility and governance accountability.
Allocation Percentages: Determine how budget and cost are distributed across AWS accounts. A 60% allocation means 60% of shared costs from that account are attributed to the corresponding workload.
Monthly vs Annual Periods: Budgets can operate on either cadence. Monthly budgets enable fine-grained spend tracking; annual budgets set broader spending envelopes.
Multi-Year Support: FinOps Center supports budget entries spanning 2024, 2025, and 2026 fiscal years with cross-year data visibility.
Integration Points
Budget onboarding feeds directly into Budget to Cloud Allocation (which maps budgets to workloads and resources) and Financial Budget Mapping to User (which connects budgets to specific users for role-based visibility). Without completed budget onboarding, no other CFM process can function.
