Multi-Account Cost Attribution
Financial institutions use separate accounts for regulatory isolation (trading, settlement, lending). Tracking costs across accounts while maintaining compliance boundaries requires specialized setup.
FinOps Consulting
FinOps for Financial Services on AWS
Financial services face unique FinOps challenges: multi-account structures for compliance, high data transfer costs for trading systems, and strict auditability for cloud spend allocation.
- The current bill is the input.
- FinOps is stood up as an operating model, not a one-off cut.
- Tags map spend to a team or a product.
- The Savings Plans portfolio is modeled against that grain.
- A named-owner cadence reviews the bill before it surprises anyone.
- The bill that remains is governed, not just lower once.
Key Challenges We Solve
High Data Transfer Costs
Real-time financial data flows between on-premises systems, AWS, and third-party APIs. Unoptimized data transfer can easily exceed compute costs.
Compliance Cost Overhead
Enhanced logging, encryption, and audit trails required for PCI DSS and SOC 2 add 10-20% to cloud costs. Need FinOps that accounts for compliance requirements.
Our Approach
Multi-Account Cost Governance
Use AWS Organizations with consolidated billing, cost allocation tags by business line (Trading, Settlement, Lending), and Athena queries for audit-grade cost reporting.
Data Transfer Optimization
Deploy AWS Direct Connect for on-prem to AWS connections, use S3 Transfer Acceleration strategically, and route traffic to reduce cross-region transfer.
Compliance-Aware Cost Optimization
Identify optimization opportunities (Reserved Instances, Savings Plans) that do not impact audit trails or encryption requirements.
Frequently Asked Questions
How do we track costs by regulatory account isolation?
Use AWS cost allocation tags by business line and regulatory requirement (e.g., `regulatory-domain: trading`, `regulatory-domain: settlement`). In consolidated billing, you can slice costs by tag and generate audit reports per domain.
What is the impact of data transfer costs on financial applications?
Data transfer can represent 20-40% of total cloud costs for financial services if not optimized. An unoptimized real-time trading system might spend $100K/month on data transfer alone. AWS Direct Connect and VPC endpoints can reduce this by 50-80%.
Are Reserved Instances compliant with SOC 2 / PCI DSS?
Yes. Reserved Instances are a pure cost mechanism and do not affect your security or compliance posture. Compliance requirements determine what resources you use (e.g., encrypted RDS); FinOps optimizes the cost of those requirements.
