The term DevOps is the end to end of two abbreviations. The first one, Dev, represents the first 3 letters of the English word Development (for development). The second, Ops, is the abbreviation of Operations (for operation).
The approach DevOps therefore makes it possible to bring together these two IT jobs and facilitate their collaboration. Recall that the DSI it's here Information Systems Department, the department which takes care of the computer park of this one. It is therefore subject to the daily changing needs of its employees. It must constantly renew itself to offer the best solutions.
The approach DevOps makes it possible to adapt as well as possible to the opportunities and needs of the market by making two teams work in close collaboration with different objectives.
On the one hand the Devs (developers) supposed to provide quick solutions and on the other hand the Ops (operational) focused on the stability and proper functioning of the solutions.

How DevOps Works
The mistake made by companies that do not have a DevOps approach in place is to develop a solution without it being tested when it is created. Once set up, the software or application is real life and sometimes may not fully meet the initial needs.
The approach DevOps is therefore essentially batteries of tests carried out continuously, thanks to the hand in hand work of Dev and Ops throughout the development phase.
The IT operations team will constantly test the application. Each new feature will undergo tests in close to real conditions.
How will the application react if it is asked to perform this calculation? How will it react if this option is activated while this one is not? In short, these are the bugs, errors, conflicts ... which will be researched by the Ops team.
The integration is permanent and follows the course of the tests. According to the older, more archaic methods, the application would be launched all at once, increasing the chances of problems here and there.
By following a precise testing process, developers can evolve step by step based on parts previously tested by the operational team and validated.
This operational aid allows you to quickly rectify potential anomalies. If there is no anomaly, the next phase can be approached.
Benefits of DevOps
DevOps significantly improves team performance. This makes it possible to lay down verified and reliable milestones. A developed phase, it is tested, then validated. The next phase can then begin. If it is not validated, the corrections are made until validating the phase to move on to the next one.
This is obviously theuser experience that is improved. The risk of bugs is reduced to the delight of users.
It is also a way to test several features to select the best according to the users. No need to start all over again since each point is validated one after the other.
The separation of the Dev and Ops teams was initially imagined for optimize the working time of each team and each focus on a defined task. It turns out that this separation and the lack of collaboration are detrimental for reasons of cost, quality and time. The tendency is therefore rather to have these teams work in close collaboration to mitigate perpetual conflicts and better satisfy users.
