許多人想導入 microservices，卻鍛羽而歸。為什麼？ 此演講以系統思考的 causal loop diagram 角度，探討 microservices 常見的導入誤區：意外的敵人 (accidental adversaries) 及捨本逐末 (shifting the burden) ，並根據系統基模角度提出對應的槓桿解。 發表於資策會創新應用服務研究所主辦之【IDEAS Tech 開源雲端軟體應用與技術研討會】, 2017-07-21. http://seminar.ithome.com.tw/live/20170721iii/ (20 minutes) 後續的 1.5 小時完整版，請見 https://school.soft-arch.net/blog/1192576/devops-a-system-dynamics-perspective
