Docker 對傳統 DevOps 工具鏈的衝擊 (Docker's Impact on traditional DevOps toolchain) - Comment

Description: A talk given to Container Summit 2015, Taipei on 2015-12-10.

【Docker 對傳統 DevOps 工具鏈的衝擊】

Docker 爆紅,以及隨之而來的生態圈,衝擊傳統 DevOps 工具鏈,任何人都無法忽視 Docker 帶來的威脅或機會。

已經上手、或正在評估 DevOps 工具的我們,該如何看待這個新局面?對哪些舊方法該持保留態度?對哪些新方法該積極學習?

本講座會鳥瞰檯面上的 DevOps 工具,提出新舊交替世代的建議方針。

Topics covered:
