你是老闆 / 決策者嗎？
對於實際負責現場的員工
有時候很怕遇到一種狀況
老闆：「我昨天聽見⋯⋯我覺
得我們公司應該要導入⋯⋯」

什麼是自動化？

自動化能夠帶來許多好處
消除重複的工作
提升軟體的交付速度（節省時間？）
降低成本、消除浪費
降低人為錯誤
消除對個體或團隊的依賴

＿＿＿＿＿萬事起頭難
會遇到的坑，比想像的多

該從何處開始著手？

從何處開始著手？
Continuous Deployment
CIcommit dev stagingtest
testprod deploy

Code
Deploy
從痛點開始
stagingdev test test production
staging test production
Project-1
Project-2
production Project-3x10

舉例
應用程式所需的 environment？
Deploy
從小處開始
如何取得 Artifacts？
是否有其他初始化的動作？
如何因應「部署失敗」？
如何連上主機？ 需要額外的組態管理？
如何因應「重新部署」？
舉例
該選用哪種技術 / 工具？
技術及工具的決策？
add or delete AWS Route53 DNS
AWS SDK for Python
Ansible Module - route53
AWS SDK for PHP
• php • API • Ansible •
舉例
技術及工具的決策？
Ansible AWS SDK
梗圖：料理東西軍，你要選哪道菜？
標準與客製
應用程式所需的 environment？
Deploy
自動化前，先標準化
如何取得 Artifacts？
是否有其他初始化的動作？
如何因應「部署失敗」？
如何連上主機？ 需要額外的組態管理？
如何因應「重新部署」？
x2 x2 x3
x3x2
x3 x2
舉例
大致標準化，預留客製空間
tasks: - name: download artifacts get_url: artifacts.zip - name: setup env templates: nginx.conf - name: reload nginx services: nginx reload
tasks: - name: download scripts get_url: deploy.sh - name: run scripts command: sh deploy.sh

即是 Code 就有
需求與優先順序
看見全貌！
不過度專注局部感謝 Ruddy 老師
在非瓶頸設備省下的
每個小時都是虛幻的。
感謝 高德拉特博士
感謝 葉秉哲 前輩

技術轉移及技能喪失
In their efforts to compensate for the unreliability of human performance, the designers of automated control systems have unwittingly created opportunities for new error types that can be even more serious than those they were seeking to avoid.
—James Reason
更多的文件、培訓、訓練

什麼是自動化？
自動化能夠帶來許多好處
但自動化的坑，比你想像的多
Oooops
自動化需要的資源（人力、工時），
也比你想像的多
自動化需要的評估關鍵，
也同樣比你想像的多
