Like DevOps, FinOps is a portmanteau word (a word made by combining two others) and a portmanteau concept. Where DevOps is the joining of development and operations, FinOps is the joining of operations and finance. Like DevOps, FinOps has arisen from a frustration with siloed business capacities, and again like DevOps, FinOps is a part cultural, part tool-driven practice.
