21. 自動化能夠帶來許多好處

22. 消除重複的工作

23. 提升軟體的交付速度
（節省時間？）

24. 降低成本、消除浪費

25. 降低人為錯誤

26. 消除對個體或團隊的依賴

39. 應用程式所需的 environment？
Deploy
從單一環節逐步開始
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」？

40. 該選用哪種技術 / 工具？

41. 技術及工具的決策？

42. 技術及工具的決策？

43. 技術及工具的決策？
add or delete GCP Cloud DNS
GCP Cloud SDK for Python
Ansible Module - gcdns_record
GCP Cloud SDK for PHP

44. 技術及工具的決策？

46. 標準與客製

47. 應用程式所需的 environment？

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」？

48. 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

58. 技術轉移及技能喪失

59. 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

60. 更多的文件、培訓、訓練

61. 持續改善及持續維護

62. 持續改善勝過追求完美

63. 自動化需要人力、工時
