DevOps : everything you need to know

Published on 28 June 2022


DevOps is a term born from the fusion of these two words: "development operations". It is a practice and a movement in computer engineering that aims to unify software development (dev) and computer operations administration (ops).


This approach appeared in 2007 and was conceptualized in 2009 by the computer scientist Patrick Dubois in Belgium. This approach allows us to improve customer satisfaction and promote high value-added solutions more quickly.


Definition : what is DevOps ?

DevOps is a set of practices and tools whose goal is to automate and integrate processes between the development and operational teams. It's about getting them to work hand in hand.

Therefore, if the two teams work together efficiency increases. Indeed, the goal is to apply the agile method to the entire project. Therefore, the constraints can be taken into account from the beginning of the project design.


Why do DevOps ?

DevOps is important because it allows to offer users a better digital experience on the applications. Software developed with this approach is more efficient and effective because the constraints have been taken into account from the beginning. This avoids unpleasant surprises such as bugs and security holes.

In addition, once the application is deployed, the collaboration continues. Indeed, when problems arise, collaborative resolution is more efficient and is completed more quickly.

This efficiency, which saves time and therefore money and increases performance, motivates and encourages teams to opt for a DevOps approach.


How does DevOps work ?

We talk aboutDevOps team. It is composed of developers and IT operations specialists. Following the merger of the two teams, they work together during the entire life of the of the product.

This team is guarantor the smooth running of the project: from development, to testing, to going online. She takes care of everything with the utmost professionalism and efficiency.

Indeed, the team uses tools to automate processes, which makes them more efficient because they are done in an in an accelerated way.


1. The life cycle


The DevOps cycle is continuous because the need for iterative improvement and ongoing collaboration is constant. Indeed, the teams are constantly working to ensure that the applications work properly.

We note that there are 6 main phases :

  • Planning : define the project requirements, the needs
  • Construction : software design
  • Continuous integration : merging new code written by several developers
  • Deployment : automate the launch of an application (ready version) for a production environment
  • Operation : configuration management
  • Ongoing feedback : soliciting and collecting feedback from customers


2. The tools

We wanted to present you the list of the most used DevOps tools this year :
