n a free devops open source Tool, no use, at least should understand! __

Wen/ Esdk

Before introducing the DevOps tool, follow the code flower to understand the following: DevOps is a what.

Devops= "Development" + "Operations".

In short, devops is used primarily for development, testing, operational communication, collaboration, and consolidation, reducing friction between development and operations, rapidly deploying software or applications, and rapid detection.

As a small white, you may have to ask: that, devops in the end is what kind of existence form, is a software or what.

Wrong... DevOps is neither a software, nor a Web site, not a code, but a group of methods, processes and systems collectively.

DevOps contains a number of good ideas and principles that encourage collaboration between the development sector and the operation and maintenance departments. In a devops environment, developers and system administrators build relationships, processes, and tools to better interact with customers and ultimately provide better services.

With a simple understanding of what DevOps is, let's take a look at the 60 best open source tools below to help you implement DevOps well.
