What is FinOps in cloud computing?
⚡
Quick Answer
FinOps is a cultural and operational practice that brings financial accountability to cloud spending, giving engineering, finance, and business shared, real-time ownership of cost so teams make value-based trade-offs.
Detailed Answer
FinOps runs an inform-optimize-operate loop: visibility via tagging and dashboards, optimization via right-sizing and pricing (spot/reservations), and governance via budgets, showback/chargeback, and anomaly alerts. It puts cost data in engineers hands so cost becomes a design consideration, not a surprise on the monthly bill.
