The need for DevOps - moving from Agile to DevOps

The era of Agile

In the technical world, the development team works on creating the product by sorting out the requirements, designing the architecture, coding the programs, testing for errors, and finally, deploying the software. This kind of approach is known as the “Ad waterfall model”.

 The main problem of this approach was when the customer wanted some changes to be made in the software. The developers were forced to rework on these changes and the process became time-consuming which resulted in increased costs for the companies. Because of this, companies realized that the waterfall model was slow for developers and thus began the search for better techniques.  So, to fix this Agile development came into existence.

 Agile development basically focused on the importance of delivering the entire software in smaller chunks of features periodically. This allowed the team of developers to break down the issues and debug the codes with multiple iterations. But this method optimized the development phase but lacked in agility in the operational phase.

Moving towards DevOps from Agile

To overcome this issue, DevOps arrived on the scene, and it’s basically a practice of bringing agility and optimization to both development and operations. These two phrases go hand in hand and ensure that software is running smoothly with constant collaboration between development and operations.
As per the DevOps culture, a single group of tech professionals will have the end-to-end responsibility of the software development from gathering the requirements for developing, testing, deployment, and finally to monitor and gather feedback from the end customers and implement changes according to the requirements.

Final Words

Agile came as an improvement on the waterfall model, but it still had limitations as it stressed only on continuous integration and monitoring. But DevOps overcame the limitations of agile with the introduction of continuous deployment in the software life cycle.
DevOps is the next big step in the tech world that promotes the concept of continuous deployment along with integration, and monitoring making DevOps approach unique. The ideology of DevOps has proved to be efficient in the production side as the changes and improvements are reflected even before the actual rollout.
