Agile is the most important principle for any software operation to work.  And the Development, as well as the Operations teams, should work together to the agility of the process. The Traditional approaches fail to produce continuous development and the integration process in the software development life cycle. Then the DevOps came into existence to enable the continuity for the development and integration process and also to increase the agility of the software process.  If you think of DevOps as a tool to establish the integration for development and integration process then you are wrong. Check our previous blog on What is DevOps to know the complete details on it. Today many tools were depending on these principles and many firms were using those tools for software development.
