    # 以微服務架構啟動金融企業的數位架構發展之路 - 張維仁 {%hackmd @k8ssummit/HJIAQ-0VP %} 過去的會計系統是資訊產業的核心,現在沒有人把會計系統變成微服務 把核心功能梳理到中台 用中台的彈性 support 應用發展 不以新技術取代舊架構,而是以新技術包容舊架構 ## 中台架構技術導入 - 架構圖 ![](https://i.imgur.com/bYglotN.jpg) ![](https://i.imgur.com/aDT3A1v.jpg) ![](https://i.imgur.com/Ns58M1B.jpg) - DevOps - 開源技術為基礎的高效CI/CD自動化,打造開發維運一體化能力 - Microservices - Containers - kubernetes 為基礎的 OpenShift 容器化管理平台基礎建設 - Clouding Computing - Event Driven - 以 kafka 為基礎的事件驅動應用系統架構設計 - Domain Driven Design - 將領域驅動融入軟體設計 ## 導入微服務 同事:不就是以前的 SOA,服務亂長就會有災難性的事情 就算是中台微服務還是有邏輯切分 規劃為 3 層架構 ### 第二個挑戰:了解 PaaS ![](https://i.imgur.com/vMbHONs.jpg) - 2015 年開始研究容器化 過去傳統領域的 IT 比較熟悉傳統的架構 有沒有一個好的容器化管理平台? ### 第二個挑戰:選擇PaaS ![](https://i.imgur.com/vcK3eyt.jpg) 竟然我國泰要做技術轉型,然後技術都要用買的嗎? 我們一定要走 Open Source ESB: enterprise service bus ### 第三個挑戰:技術團隊組織的組成 傳統 IT 團隊嘗試導入 DevOps 中台根據中台的方式規劃團隊 ## 持續面對的挑戰:雲端技術的衝擊 嘗試發展 Event-Driven 跨雲/異地的同步工具的應用 kubernetes 已成為移植雲端的主要技術 目前研究的重點: Kubernetes Management Platform ###### tags: `k8ssummit20` `k8s` 國泰金控 國泰2015數位轉型, 麥肯錫合作, 首席架構師 數位轉型, 非技術轉型, 應包含客戶的轉型, 企業的轉型 如果用技術數位轉型輔客戶業務轉型.以客戶為中心的橫向全通路架構 找到很好架構來輔助. integration 是key 整體資訊架構設計的關鍵是技術中台integration 同時業務中台也是發展重點 過去金融是大核心, 保險核心, 金融核心, 但是現在 要將服務 分解成小核心, 但要怎麼拆, 拔哪個服務是很重要的 各類核心系統-->資訊服務中心-->數位通路與生態圖 用新的包含舊的核心, 不一定要拆舊核心 中台架構需先定位, 再技術導入 DevOps,Microservices,Containers,Clouding Computing,Event Driven,Domain Driven Design 寫程式一天,走流程要三週...不切實際 服務怎麼拆解,才不會是個災難, 沒有經驗或參考, 如何避免地雷踏太多, 使用domain driven desing關鍵機制 第一個挑戰,導入微服務 第二個挑戰,了解PassS , 怎麼選? 一定要用買的嗎? 使用opensource職能, 避免被掐住.後來選擇openshift 目標:用中台技術+微服務技術來包容舊技術 在ESB的強大的功能, 但不見的適用, 如以中台取代.故在選擇JBOSS 同時要考慮資安 以開源方案為主開發相關op 第三個挑戰,技術團隊組織的組成 切分傳統IT組織, 另新增微服務技術團隊 嘗試發展Event-driven
