The role of DevOps

In today’s world, software plays an increasingly important role in all industries and sectors. To stay competitive and meet increasing demands, companies need to be able to deliver high-quality software quickly and reliably. This is where DevOps comes in, a philosophy and practice that focuses on collaboration between developers and IT teams to enable faster and more reliable software delivery. In this blog post, we will look at the definition of DevOps and what it means for software development and delivery.


What does DevOps mean?

DevOps is a term that originated from the combination of “development” and “operations”. It describes an approach to software development and IT operations that focuses on collaboration between developers and IT teams to enable faster and more reliable software delivery. The DevOps philosophy combines the principles of Agile, Lean and IT Service Management to create a culture of collaboration and integration. The goal is to create a system where developers and IT experts work together to deliver applications faster and more reliably.


Why is DevOps important?

One of the main benefits of DevOps is improving time-to-market. Collaboration between developers and IT teams allows software updates and features to be delivered faster. In addition, DevOps also enables higher quality applications, as automated testing and monitoring can identify and fix problems early on.
Overall, DevOps offers a way to improve collaboration between developers and IT teams, increase the quality and reliability of applications and shorten time-to-market. Given the growing importance of software in many industries, DevOps is becoming an increasingly important approach to deploying applications and systems.


What are DevOps practices?

DevOps practices are methods and processes used in software development and IT operations to enable fast, reliable and continuous delivery of software. They include Continuous Integration (CI), Continuous Delivery (CD), Continuous Deployment (CD) and Infrastructure as Code (IaC).

Continuous Integration (CI) is a DevOps practice in which code changes are regularly tested in an automated manner and integrated into a shared repository. This practice ensures that all changes in the code work and that there are no conflicts with other pieces of code.

Continuous Delivery (CD) is an extension of CI where tested changes are deployed automatically in a production-like environment. This means that code is automatically tested and released with each build, allowing new features to be delivered to users faster.

Continuous Deployment (CD) goes a step further than CD and refers to a DevOps practice where changes are automatically moved into production. However, this involves checking certain conditions, such as certain tests that could fail.

Infrastructure as Code (IaC) means that the entire infrastructure is managed in an automated way. In this process, the infrastructure is written in code and this code is stored in a version control system. This enables fast and repeatable deployment of systems and minimises a source of errors due to manual intervention. The entire infrastructure can thus be deployed and changed quickly, efficiently and automatically.


The DevOps culture

The DevOps culture is an essential component of DevOps and describes the way teams work together in software development and IT operations. A DevOps culture is characterised by an open, communicative and cooperative way of working. Agile methods are often used to be able to react quickly and efficiently to changes and requirements. Automation of processes is another important aspect to minimise errors and enable an efficient way of working. A DevOps culture also encourages an open error culture, where mistakes are not seen as personal failures but as opportunities for improvement. A strong focus on the needs of customers completes the picture of a DevOps culture.


Best practices for the introduction of DevOps

Implementing DevOps can be challenging, especially if it is to be implemented in a company or organisation that is previously unfamiliar with this way of working. Some best practices are:

  • Encourage collaboration: Collaboration between development and operations should be encouraged, with both teams working together regularly to develop a shared vision and strategy.
  • Introduce automation: Automation should be introduced gradually by first identifying manual processes that can be automated. This can help improve efficiency and quality and minimise errors.
  • Continuous feedback: Regular feedback from customers and users can improve the quality of products and services. Feedback between teams should also be encouraged to respond quickly to problems.
  • Use agile methods: Agile methods such as Scrum or Kanban can help to improve collaboration between teams, increase efficiency and respond more quickly to changes and requirements.
    Promote corporate culture: A corporate culture that supports change and innovation and promotes a positive culture of error can help make DevOps adoption easier and more successful.


In summary, DevOps is a way of working that focuses on close collaboration between development and operations and the automation of processes. This should minimise errors, increase efficiency and improve the quality of products and services.
One advantage of DevOps is that it enables faster and more efficient development and deployment of software. Errors can also be discovered and corrected more quickly. In addition, DevOps promotes an open error culture and collaboration between teams.
A disadvantage can be that the introduction of DevOps is a big change for companies and the implementation requires time and resources. Complex and interdisciplinary processes can also be a challenge.

We, the esc, already use DevOps practices to ensure efficient and high-quality software development and to provide the best possible service to our customers.
