企業等級的IT運作

Business User 的期待• 應用開發可即時交付，上線

順利• Time to Market

• App Team 的產出符合期待• 任何情況下，都不要有服務

中斷• 需求變更容易

App Team 常見問題• Business User 需求不明確• 需求訪談與開發進度緩慢• 架構設計問題，以致改版困

難• 部署程序複雜，造成服務中

斷• 擴容/HA/DR皆需仰賴 infra

team 協助，資源調度不易，時間冗長

Infra Team 常見問題• Server 上線前的準備工作• Side Survey

• 機架• 網路線• IP

• 防火牆• 安裝OS、Middleware、監控• 有IaaS之後• …...
