DevOps is gaining more and more followers in the IT world. In this article, you will discover the essential points about the concept.
DevOps or “Development” + “Operations” is a technical term that more or less carries an ambiguity. Process, rule or other, it is often referred to when talking about practices to improve collaboration within teams. To remove this ambiguity, it is worth detailing the key points around which the term DevOps revolves.

What is DevOps?
The term DevOps is fairly new in the world ofIT. It was only created in 2009. It is Patrick Debois who invented it by combining the two terms ” development ” and ” operations “. According to supporters, the term refers to a certain culture that is often associated with other terms.
Thus, the terms “DevOps environment” refers to an IT organization that has chosen it as a culture. On the other hand, the term “DevOps movement” is used when talking about adoption rates or trends for the future. However, it is still difficult to define the term. It is safer to consider what Gartner says.
Indeed, Gartner defined the term by arguing that it is ” change in computer culture “. The change, according to him, is the result of a ” adoption of agile and lean practices in the context of a systems approach “.
The goal being to seek better collaboration including teams and operations for development. DevOps thus includes feedback in order to offer features, improvements and updates more often. Moreover, the model supports the stability, but especially the security of the software created.
We’ll come back to this a bit below when we develop the nuance between DevOps and DevSecOps. Before that, we should first go to the origin of the DevOps model.
Origin of DevOps
Although the term only came into existence very recently, IT experts have already been developing it for a long time. Indeed, the main players in the IT field (developers and administrators) have disparate ideas regarding IT development.
On the user side, professionals still want innovatethat is, to take advantage of new features and services. In addition, they want to experience more change fast. At the same time, these professionals demand a certain stability.
Such a change creates a dilemma for developers. Between high quality software and stable use, developers and administrators are forced to find a middle ground for the good of computing.
DevOps was thus born out of the resolution of the development dilemma. It proposes to integrate all stakeholders in the deployment of new software. This collaboration aims to deliver software of good quality while ensuring that the system remains stable in its entirety. Therefore, the term DevOps and the data center principle are closely related.
How do you create such a culture?
The key players in IT development must thus join forces to achieve a common goal. To do this, they must first establish a climate of understanding overcoming the traditional boundaries and roles of each discipline.
Some examples of work to be done include:
- Reach agreement in terms of starting principles;
- Establishing priorities and core beliefs;
- Prioritize collaboration among all team members as well as between teams to solve problems;
- Integrate theautomation repetitive and routine tasks in order to spend more time on more important tasks ;
- Evaluate the status of work as teams progress;
- Perform a feedback with measurable indicators;
- Opting for wide dissemination of data to support successful teamwork;
- Differences and disparate specialties should be viewed as assets, not roadblocks.
DevOps and DevSecOps, what’s the difference?
The notion of DevSecOps refers to the DevOps model. The former refers to the practice of defending the entire DevOps environment. It thus requires strategies, processes and techniques.
The notion of DevSecOps comes into play from the design to the maintenance of a DevOps environment, and even beyond. To be clear, DevSecOps is about developing security more quickly, without compromising security. This requires close collaboration between release engineers and security teams.
Therefore, the DevSecOps model strives to solve the problems from their appearance without waiting for them to cause damage. This means more security for the whole system.
The Benefits of DevOps
Considering all the above, it can be said that DevOps has a number of advantages. Here they are:
Speed of innovation
Innovation is faster when teams embed DevOps culture within the company. Such a practice allows to Adapt to change of the markets, and, as a result, to post more substantial sales figures.
Speed of delivery
Speed of delivery means a significant improvement in the production process. It also means a pace more high in creating new software releases. This creates a competitive advantage in the market.
A DevOps culture accesses closer collaboration between all players within the operational teams. This will then create a sense of responsibility for the benefit of the entire team.
Adopting a DevOps model indicates that there is automation of repetitive tasks, including automated security tools. This increases the security level of the entire system.
How the DevOps Model Works
In general, there are common features To all DevOps models. These are primarily collaboration and automation. However, a series of continuous tasks such as integration, delivery, testing, monitoring and remediation are part of the usual functionality. Nevertheless, there are many variants specific to each model.
As the name implies, collaboration involves all members of all teams in IT development and operations. However, collaboration is not limited to this set, it goes far beyond this circle. Operations development is meaningless without delivery, management and testing.
We also need to talk about how teams work together. Each individual in isolation has skills. Only teamwork allows foradvance more quickly while demonstrating efficiency.
In order to focus on the more “noble” tasks, you need to automate parts of the workflow. This is one of the principles behind the DevOps culture. L’automation on the other hand, requires a set oftools (purchased, created, open source, etc.) used to deploy the software so created.
Integration is a core principle of DevOps culture. This set of practices encourages developers to check the relevance and stability of source code on a daily basis. Such a technique avoids the copy of one developer’s project by another within the team.
Continuous testing is required to ensure thatavoid to deliver defective software. In addition, frequent updates and new features require testing from time to time to satisfy the user experience. Continuous testing also helps to guard against potential security risks.
As for continuous delivery, it consists of ensuring the security and the quality of deployed software. According to studies, companies that rely on a DevOps model make multiple deliveries in a single day. This is significantly more frequent than those that deploy on average once a week or even once a month.
Finally, let’s talk about monitoring. Continuous monitoring of products allows us to predict, detect and correct failures. It is also continuous monitoring that improves the stability of software.
Continuous monitoring thus requires a proactive and rigorous team. This is to ensure the monitoring of servers as well as the performance of applications. To ensure continuity of monitoring, it is also necessary to establish a event history. Thus, all information obtained from the monitoring results will be included.
Who is using DevOps today?
Regardless of age, most companies are currently implementing DevOps. Surveys conducted on the topic have shown a more significant figure (74% of current companies).
Firms working for the web like GAFAM, in particular Facebook and Amazon Are the pioneers of the DevOps model. However, almost all types of businesses are implementing it lately. The success of financial services giant Barclay Bank or multimedia titan Sony Pictures is a testament to how widespread the practice is.
Nevertheless, startups like SME are opting for DevOps in their production process. This leads to the conclusion that neither size nor seniority determines the success of such a model. Even government and semi-government organizations are adopting it today. However, experts in the field still feel the need to expand its scope.
