The GenAI-driven explosion in GPU and inference cost, why the FinOps Foundation FOCUS spec became the de-facto common vocabulary, how Vantage took multi-cloud visibility, how Infracost moved cost decisions into the PR cycle, the OpenCost (CNCF) versus IBM-acquired Kubecost (2024) split, CloudZero unit cost economics, Cloudability (Apptio then IBM) for the enterprise, Spot.io under NetApp for spot automation, Densify / ProsperOps / FinOut / Anodot / Yotascale, the OSS inventory Komiser, Capital One Cloud Custodian for policy, Intel-acquired Granulate for workload tuning, and real cases from Toss / Kakao / Mercari / Cybozu — closing with showback vs chargeback, RI/SP strategy, and a decision guide for who should pick what.

GenAI로 폭증한 GPU/추론 비용, FinOps Foundation의 FOCUS 표준이 사실상 산업 공통어가 된 이야기, Vantage가 멀티 클라우드 가시성을 가져간 흐름, Infracost가 IaC PR 차이를 보여주는 방식, OpenCost(CNCF)와 IBM이 인수한 Kubecost(2024)의 분기, CloudZero의 unit cost economics, Cloudability(Apptio→IBM) 엔터프라이즈, NetApp 산하 Spot.io의 스팟 자동화, Densify/ProsperOps/FinOut/Anodot/Yotascale, OSS 인벤토리 Komiser와 정책 엔진 Cloud Custodian, Intel이 인수한 Granulate, 그리고 토스/카카오/Mercari/Cybozu의 실제 비용 운영 사례까지 — showback vs chargeback, RI/SP, 어떤 조직이 무엇을 골라야 하는지 의사결정 가이드로 마무리한다.
