Discover a comprehensive list of DevOps tools segmented according to each phase of the software development lifecycle.

There are two primary approaches in DevOps tools; an all-in-one approach and an open toolchain approach. An all-in-one DevOps solution provides a complete end-to-end solution that usually doesn’t integrate with other third-party tools. An open toolchain can be customized with different tools for a team’s needs. 

We at Middleware firmly believe that the open toolchain approach is the best approach because it allows the primary DevOps tool to be customized with third-party tools according to the organization’s unique needs.

The widespread adoption of the open toolchain approach is one of the reasons why 83% of IT decision-makers reported implementing DevOps practices to unlock higher business value.

What is DevOps

DevOps is a set of practices, tools, and cultural philosophy that helps organizations improve their ability to deliver applications and services at scale. 

Today, DevOps is the next step of agile methodologies. A culture transformation that brings your development and operations teams together.

What are DevOps tools?

DevOps tools are a set of tools that helps organizations effectively adopt the DevOps methodology across the multiple phases of the development lifecycle. DevOps tools help organizations ensure that transparency, automation, and collaboration always stay at the core of their development lifecycle. 

There is no “one-size-fits-all” solution in the DevOps tools space. As a result, various tools are available for every phase of the lifecycle. Choosing one that matches your needs is the key to successfully implementing the DevOps lifecycle. 

Here in this article, we have segmented the tools based on the key phases of a DevOps development lifecycle:
