Worldwide interest and adoption of Devops is growing rapidly. But what is DevOps?
DevOps is a set of practices that focuses on collaboration and communication between software developers and IT operations professionals, automating the software delivery process and infrastructure changes. The term DevOps was born from the union of “development” and “operations,” which aims to foster better communication between the two teams.
DevOps aims to create a culture and environment in which software design, testing and delivery can be done quickly, frequently and efficiently. DevOps is not just a methodology, it is a true work philosophy.
What is DevOps? And how did the approach come about?
Today, companies are evolving towards a dynamic customer-oriented approach to the development and delivery of their applications. In an environment where customers are turning to digital transactions in the mobile age, the role of application developers is becoming an essential part of the customer experience. At the same time, the trend towards agility has been a source of inspiration for DevOps, one of whose agile key points favors professionals and their interaction rather than processes and tools.
Over the past few years, the development and operations teams have significantly improved the way they work. But today, the need to realign these two teams is growing. The DevOps movement is born out of this need for realignment. DevOps is at the origin of a philosophy that completely transforms the way IT professionals perceive the stability and functioning of the system they manage, as well as their own role in the flow of added value from start to finish. Cloud Computing and Software-Defined Networks (SDNs) are two elements that have accelerated the breaking down of the silos that separated development and operations teams.
The “development VS operations” rivalry is disappearing, albeit gradually, as the two departments are increasingly aware that they are part of the same team and working towards the same goal. DevOps enables companies to be responsive to time to market with speed and thus, to satisfy customer needs.
The DevOps Movement
The DevOps movement brings together, and continues to integrate, many principles and best practices that can be adopted by IT organizations of all sizes (internal or external). All these experiences have created an approach that aims to improve the way IT brings added value to its customers. DevOps certified professionals meet this objective through improved communication and collaboration between IT teams and better integration of techniques, processes and people.
8 benefits of adopting the DevOps approach
1 Improved quality of code, products and services (reduced anomalies, higher change success rate, etc.).
2 Increased efficiency (e.g. optimization of time spent on value-adding activities: unprecedented value for the customer)
3 Improved time to market
4 Better alignment between IT and the business lines
5 Smaller versions provided very quickly and frequently
6 Productivity improvement, customer satisfaction, staff satisfaction
7 Less risk and fewer setbacks
8 Long-term cost reduction
The founding steps of DevOps
The DevOps movement is based on the adoption and integration of three main current approaches or methods:
Agile software development methods such as Scrum.
IT Service Management (ITSM) linked to the best practices recommended by ITIL.
Lean, which allows to optimize work and improve the quality of production.
DevOps’ cultural change
DevOps is not a method or process change. It requires a change in organizational culture. The conflicting objectives of IT departments make this cultural change difficult. Operations teams are looking for stability while developers require frequent changes and testers are there to minimize risk. The collaboration and intelligent integration of these teams is a critical challenge to the adoption of DevOps in a company.
The DevOps job market
Due to the customer-oriented development of companies and the increasing adoption of DevOps, this DevOps competence (or dual competence: developer and system engineer) is more and more sought after by companies. A study unveils and testifies to the top 5 functions under pressure on the job market in the IT and digital sector (study, published in August 2017 by RégionsJob).
