To understand the basic philosophies on which DevOps as an ideology is constructed around, it is important to establish the problem that DevOps has set out to solve. Simply put, the goal of DevOps is to create superior-quality software, more quickly and with more reliability while ensuring greater communication and collaboration between teams. In other words, DevOps aims to aim the bridge between development and IT operations, which make up one half each of Dev+Ops. In an organization, both these departments might be working with great efficiency, but if they do not work in unity, business results are affected. DevOps is, in that sense, an ideology that marries development and operations teams.

Next, let’s understand the 5 pillars around which the entire DevOps ideology revolves around.
In the DevOps life cycle, this is the stage where the Software is developed continuously. Unlike the traditional ‘waterfall model’, continuous development ensures that multiple software deliverables are broken down into multiple sprints of short development cycles, developed swiftly and delivered in a very short time.
The next logical step is obviously to ensure that software created through continuous development is continuously tested for bugs. For this, there are multiple DevOps testing tools available that help quality analysts seamlessly test code in parallel, ensuring that there are no functionality flaws
This is the stage where the code supporting new functionality is added to top up the existing code. Updated code needs to be integrated in almost real-time, since in DevOps, the process of development is continuous. Changes need to be reflected to end users swiftly, and developers need to ensure that there are no errors in the runtime environment. Again, there are open source DevOps tools that help you integrate new code with old.
Here’s when the code is deployed into the production environment. Developers need to ensure that the code is correctly deployed on all relevant servers. Along the way, if any new functionality or feature needs to be introduced midway, it might result in increase of say, website traffic. In such a scenario, additional servers need to be deployed to ensure business continuity. Hence, system admins who operate as part of a DevOps ecosystem should ensure that his/her tasks are executed quickly with no disruption to existing operations. Of course, here too there are tools to help you out.
The next (and probably last) logical stage is to monitor the performance of the software and continually improve its performance. The operations team of an organization plays a very crucial role here, in monitoring user activity in real-time to identify bugs or unexpected app behaviour. As in other stages of DevOps, there are exclusive tools available that continually look out for variations in application performance, flagging irregularities in real-time.
Once you understand these basic pillars around which DevOps is built, it is simple to deploy a learn-as-you-so philosophy to your business. All the best in adopting the DevOps way of life!
