SLO examples for financial services: what good performance looks like in fintech
Short summary
Fintech SLOs must meet regulatory baselines (FDIC 99.9% uptime, DORA continuous availability) due to compliance mandates and user trust costs. Three-tier framework spans payment-critical paths (99.95%), authentication (99.9%), and non-payment flows (99.9%) with p99 latency and error-ratio targets. Error budgets translate SLOs into deployment policies; continuous measurement validates compliance in real time.
- •FDIC and DORA regulations set strict uptime and availability requirements for financial services vendors
- •Three-tier SLO structure with specific latency targets (p95/p99) and error budgets for each transaction tier
- •Continuous SLO measurement and resilience testing guide release decisions and incident response
