关于敏捷Agile和DevOps都已经有无数的文章谈及,但是还是有很多人经常将二者混为一谈。特别是很多DevOps的文章中又往往提到了敏捷开发,因此,两种技术很容易被大家互认定为彼此,于是就有更多的人被搞糊涂了。为了将二者区分开,笔者查询了一系列的文档,特此将二者的区别在此列一下,希望能够帮助大家搞清楚二者。
一、概念不同
敏捷软件开发(Agile software development),又称敏捷开发,是一种从1990年代开始逐渐引起广泛关注的新型软件开发方法,是一种能应对快速变化需求的软件开发能力。如上所示,敏捷是一种提倡迭代、协作和持续评估的方法,所有这些都是为了持续改进。当开发团队采用敏捷方法时,它依赖于客户的反馈,将开发项目划分为更小的任务,并发布更小的迭代,以完成对交付的改进。敏捷运动的起源是2001年的敏捷宣言。当时没有人意识到敏捷的经济意义。敏捷从来没有以这种方式计划过。
根据维基百科对DevOps的定义:DevOps是将软件开发(Dev)和运维(Ops)结合在一起的一组实践,旨在缩短系统开发生命周期并提供具有高质量软件的连续交付。
简而言之,DevOps是为了简化开发和交付工作流程而将开发和操作团队合并的一种实践。通过将开发团队和运维团队聚集在一起,打破之前的壁垒,使得开发周期可以变得更加高效。DevOps允许以较小的增量部署软件迭代。在DevOps中,更多考虑的是投资回报。
二、目标不同
敏捷目标是持续的变化和持续的改进,而DevOps的重点则是将开发和运维过程的不同阶段统一为一个无缝的循环。
三、关注点不同
敏捷开发关注于软件开发的迭代。其帮助开发团队以更高效的方式组织任务,一次只关注一个迭代,以保证在更短的时间内进行更有效的冲刺。而DevOps则致力于自动化软件开发帮助团队处理许多任务。DevOps更加关注的是持续集成和持续交付的整体过程。
四、变革内容不同
敏捷开发更多的是技术方面的变革,其更多的依赖于工具的支持;而DevOps更加强调的是开发团队和运维团队的无缝结合,对组织而言更像是一种在组织和文化方面的变革。
在二者结合时,DevOps团队可以像敏捷团队一样依赖于自动化测试和自动化交付。

Countless articles have discussed Agile and DevOps, yet many people still confuse the two. Particularly since many DevOps articles also mention agile development, these two technologies are easily mistaken for each other, leading to more confusion. To distinguish between them, the author has consulted a series of documents and listed the differences here, hoping to help everyone understand both clearly.
1. Different Concepts
Agile software development, also known as agile development, is a new software development method that has gradually attracted widespread attention since the 1990s. It is a software development capability that can respond to rapidly changing requirements. Agile is an approach that advocates iteration, collaboration, and continuous evaluation, all for continuous improvement. When a development team adopts an agile approach, it relies on customer feedback, divides development projects into smaller tasks, and releases smaller iterations to improve delivery. The origin of the agile movement was the Agile Manifesto in 2001. At that time, no one realized the economic significance of agile. Agile was never planned that way.
According to Wikipedia's definition of DevOps: DevOps is a set of practices that combines software development (Dev) and operations (Ops), aimed at shortening the systems development life cycle and providing continuous delivery of high-quality software.
In short, DevOps is a practice of merging development and operations teams to simplify development and delivery workflows. By bringing development and operations teams together and breaking down previous barriers, development cycles can become more efficient. DevOps allows software iterations to be deployed in smaller increments. In DevOps, more consideration is given to return on investment.
2. Different Goals
The agile goal is continuous change and continuous improvement, while DevOps focuses on unifying the different stages of development and operations processes into a seamless loop.
3. Different Focus Areas
Agile development focuses on iterations in software development. It helps development teams organize tasks more efficiently, focusing on one iteration at a time to ensure more effective sprints in shorter timeframes. DevOps, on the other hand, is dedicated to automating software development to help teams handle many tasks. DevOps focuses more on the overall process of continuous integration and continuous delivery.
4. Different Types of Change
Agile development is more of a technical change, relying more on tool support; while DevOps emphasizes the seamless integration of development and operations teams, representing more of an organizational and cultural change for the organization.
When combined, DevOps teams can rely on automated testing and automated delivery just like agile teams.
