DevOps comes from "Dev" (development) and "Ops" (operations). This operational method is increasingly used not only for software development, but also for Machine Learning and Data Science.
The DevOps concept
The development and operations teams, although working in the same field, have totally different ways of conceiving things.

While developers often use the agile method, operational staff mostly turn to the ITIL method. DevOps unifies the teams, processes and technologies of both professions. It involves IT operations in planning, tracking, development, testing, delivery, monitoring and operations. By adopting the DevOps method on a day-to-day basis, teams are able to achieve their objectives more quickly and respond better to customer needs.
The project is therefore built from A to Z with all the professions involved. The combination of these practices and tools is designed to improve an organization's ability to deliver high-quality applications and software.

The benefits of DevOps
There are 4 main advantages to this method:
Speed of delivery
This method enables us to deliver the requested product or service much more quickly. Indeed, thanks to continuous delivery, teams can receive feedback more quickly. Operational staff guide developers in correcting bugs. In this way, automation will enable teams to create and test early to guarantee delivery.
Improved internal collaboration
This collaboration between developers and operational teams leads to a sharing of responsibilities, methods and tools. DevOps improves the efficiency of these teams, and communication between them, who previously worked in isolation from each other. This brings a great deal of human value to an organization.
Increased quality and reliability
This process guarantees compliance with security and reliability standards. Application updates or infrastructure changes, for example, will be carried out by both teams in agreement. Security, meanwhile, will remain at a high level, thanks to automated compliance rules, configuration techniques and frequent checks by the teams.
Adaptability to market needs
This method is truly beneficial for effectively improving and innovating today's software techniques. Bug-fixing, early testing and frequent updates provide a real competitive advantage for the organization. Teams are better able to respond quickly to customer requests. And they are more responsive to external changes and internal needs.

The application lifecycle with DevOps

The application lifecycle is strongly impacted by the DevOps method. The various phases of this cycle are not role-specific. The phases are as follows:
Plan (PLAN)
This planning must be based on the Agile method. In a nutshell, agility means organizing "sprints" - short, planned, structured meetings. Teams come together to coordinate, collaborate and manage tasks. Agile rituals help create a dynamic, responsive work environment. This promotes rapid delivery and quality of service.

Developing (DEVELOP)
À Basically, the development phase involves all aspects of coding an application or software. This generally includes writing, testing, revising and integrating code by team members. It is this phase that will promote continuous integration using productive tools, automation and testing. Subsequently, these steps will make the team productive and efficient for delivery.

DELIVER
Application delivery generally takes place in different environments. For example, depending on the customer's needs, the basic infrastructure, deployment or configuration make up these different environments. For this phase, the teams set up a task management process to track the stages right through to delivery to the customer.

OPERATE
This phase covers after-sales service, updates, maintenance, application troubleshooting and supervision. Teams must ensure the security, governance and reliability of their product. The aim of this process is to avoid bugs, and prevent problems before they impact the customer.
