    # 如何讓 FinOps 成為 DevOps 的得力助手? - 楊琬晴 (Rose Yang) {%hackmd @DevOpsDay/BymyqYaeo %} > 各家講者出來分享自己的經驗多少都有些公司內規和公關要求的限制,有些不方便分享的地方(例如:不要張貼簡報截圖)還請大家多多包涵喔(不然就更多人不敢出來分享了) > [name=DevOpsDays Taipei 2022] > 從這開始 (blog: https://www.cpht.pro/blog/blog-post-30) ## 定義 FinOps: Financial + Operations ## 痛點 Pain Point - 雲端用著用著,錢怎麼越花越多 - 混合雲架構,成本支出也越來越高 - 雲端支出增加,94%正在雲端浪費,浪費比例達32%(高於去年的30%) - 雲預算逐年增加,到底是因為業務增加而成長,還是因為過去超支而增加? - 因監控不清楚而造成超支 - 更常發生於具有大量雲端預算的企業 ### 雲端支出策略通點 - 隨需部署與彈性縮放不適用傳統IT流程 - 雲成本模型複雜 - 缺乏可視化 - 跨雲的帳務報表不易整合 - 人工計算? - 執行工程師通常看不到Billing report > 編按:產品的實際成本對工程師無感? - 跨雲環境下,帳務報表整合不易 ## 導入目標(Goal) > 不是要Costdown,而是要確保每一分錢花得值得 ## Trend - 國外:2020起,相關需求增加 - 台灣相對較少 ## FinOps框架 (From [FinOps Foundation]()) - 六領域 - 了解雲端用量與成本 - 績效追蹤與標竿管理 - 即時的決策 - 雲端用量最佳化 - 雲端費率最佳化 - 組織一制性 - 18能力 - 成本分配 - 資訊收集與正規化 - 預算管理 - 資源運用與效率 - 預測 - 建立文化 - 雲端政策與管理 - ... ## FinOps工具 `OpenCost`: [CNCF沙盒專案](https://github.com/opencost/opencost?utm_source=thenewstack&utm_medium=website&utm_content=inline-mention&utm_campaign=platform),目前只能適用於k8s * 即時性資源分配與花費 * 依不同維度聚集 * 成本正規化 * 支援主流監控工具的整合 * 集群與成本監控告警 * 可串接雲端供應商的帳務報表 可自定義價格表,不是只有雲端商可使用 ### 功能 e.g., 收集Usage資訊(CPU\memory, etc.),將收集資訊與雲端賬單報表正規化後,分析投資費用的使用效率 標示idle資源與其對應之付出成本,明確顯示其成本分配與效率。 ## FinOps實踐 1. 成熟度評估 * 落差分析 * 按階段導入 * 取得認知與共識 2. 建立資源部署政策 * metadata策略 * IaC + PaC 3. 建立測量指標 * 按角色所需 4. 資源使用與成本分析 5. 雲端成本策略優化 ###### tags: `DevOpsDays Taipei 2022`、`FinOps`、`cost`、`成本管理`
