What is DevOps and how it work?

In Traditional software development, after completing the development part, the code deployment time was huge. And many times, we heard the common fights between the Development Team and Operations Team or deployment team that it works fine on our system, it's the sever causing problem and operation team defences it's not your server it's your code, Right? Well, DevOps solves the Traditional Dev and Ops fights by breaking the wall of confusion.

What is DevOps

DevOps is Development and Operation’s Collaboration, It’s a Union of Process, People and Working Product that enable continuous integration and continuous delivery of value to our end users.

Also, it minimizing the risk factor by continuously delivering and getting end-users and stakeholders feedback at the early stages.

How DevOps Works

DevOps is the practice of operations and development engineers that work together in the entire project lifecycle, from design and development process to production releases and support.

Starting from design and development to testing automation and from continuous integration to continuous delivery, the team works together to achieve the desired goal. People having both development and operations skill sets working together and use various tools for CI-CD and Monitoring to respond quickly to customers need and fix issues and bugs.

Benefits of DevOps

Security

While implementing automation Security is a very important factor, By Following DevOps model and using Infrastructure as code and by doing automation of process and compliance policies, one can take control security configuration.
