Effective DevOps:一場文化與技術的轉型運動

597 views

Published on

席捲全世界的 DevOps 運動,不只關乎於技術,更一再被證實它與組織、團隊文化密不可分,究竟全世界這麼多專家、技術傳教士在提到 DevOps 時到底都在談些什麼?本場分享將和大家聊一聊 DevOps 究竟在文化和技術層面帶來哪些了轉變,以及我們又應該用什麼樣的心態與角度來看待這場轉型運動。

備註:這場分享並非全部都是新內容,是之前於 Agile Tour Taichung 2017 分享過的「到底 DevOps 在談些什麼玩意兒?」的刪減更新版。

  19. 19. 定義
  20. 20. DevOps (a clipped compound of development and operations) is a term used to refer to a set of practices that emphasizes the collaboration and communication of both software developers and other information-technology (IT) professionals while automating the process of software delivery and infrastructure changes.It aims at establishing a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably. : https://zh.wikipedia.org/wiki/DevOps Wikipedia
  21. 21. DevOps represents a change in IT culture, focusing on rapid IT service delivery through the adoption of agile, lean practices in the context of a system-oriented approach. DevOps emphasizes people (and culture), and seeks to improve collaboration between operations and development teams. DevOps implementations utilize technology — especially automation tools that can leverage an increasingly programmable and dynamic infrastructure from a life cycle perspective. : http://www.gartner.com/it-glossary/devops/ Gartner
  22. 22. A philosophy that brings together operations and development DevOps is an approach that promotes closer collaboration between lines of business, development and IT operations. It is an enterprise capability that enables the continuous delivery, continuous deployment and continuous monitoring of applications. It reduces the time needed to address customer feedback. Development and operations, and even testing, were often siloed in the past. DevOps brings them together to improve agility. : https://www.ibm.com/cloud-computing/what-is-devops IBM
  23. 23. DevOps : https://aws.amazon.com/tw/devops/what-is-devops/ AWS
  24. 24. DevOps is… A cultural and professional movement, focused on how we build and operate high velocity organisations, born from the experiences of its practitioners. : https://www.chef.io/solutions/devops/ Chef
  25. 25. Devops is a cultural movement that changes how individuals think about their work, values the diversity of work done, supports intentional processes that accelerate the rate by which businesses realize value, and measures the effect of social and technical change. It is a way of thinking and a way of working that enables individuals and organizations to develop and maintain sustainable work practices. It is a cultural framework for sharing stories and developing empathy, enabling people and teams to practice their crafts in effective and lasting ways. : Effective DevOps P.13, Publisher: O'Reilly Media.

  110. 110. Jeff Geerling 《Ansible for DevOps》 “My advice: spend less time arguing over the definition of the word, and more time making it mean something to you.”
  111. 111. Leaders need to realize that implementing DevOps means changing the technology system as well as the cultural system. They must acknowledge that both are intertwined and, to be successful, both systems must evolve to drive velocity.” Learning how to manage and lead by giving people context and information to make better decisions— versus giving them tickets or briefs—is how leaders and teams will thrive. : https://blog.chef.io/2016/10/06/future-of-devops-with-adam-jacob/ Chef CTO Adam Jacob
