	Before introducing DevOps tools, follow the code flower to understand: what is DevOps?



	





	





	





	





	





	





	





	





	





	





	





	Devops= "Development" + "Operations".



	





	





	In short, devops is used primarily for development, testing, communication between operations, collaboration and integration, reducing friction between development and operations, enabling rapid deployment of software or applications, and rapid detection.



	





	





	





	





	





	





	





	





	





	





	





	As a small white, you may have to ask: So, what is DevOps, a software or a form of existence?



	





	





	Wrong!!! DevOps is neither software nor Web sites, nor code, but a set of methods, processes, and systems collectively.



	





	





	DevOps encompasses a number of good ideas and principles that encourage collaboration between the development and operations departments. In a devops environment, developers and system administrators build relationships, processes, and tools to better engage with customers and ultimately deliver better services.



	





	





	





	





	





	With a quick overview of what DevOps is all about, take a look at these 60 best open source tools to help you implement DevOps well.
