If you work in IT, you've probably already heard of it. But what is DevOps? First of all, DevOps refers to all the tasks carried out by a company's teams responsible for developing applications (Dev) and operating systems (Ops). The term DevOps is a contraction of development and operations.
The role of each
- Devs: We're talking about all the people involved in making the software before it reaches production. These include developers, product managers, testers, product owners and QAs. Developers are responsible for producing innovation and delivering new functionality to users as soon as possible.
- Ops: These are the people involved in the operation and maintenance of production: systems engineers, DBAs, network engineers, security staff, etc. Operations engineers are responsible for ensuring that users have access to a stable, fast and responsive system.
To put it more succinctly, Devs are looking for change, through the frequent delivery of new functionalities. Ops, on the other hand, are looking for organisational stability.
DevOps is not just a methodology, it's a real working philosophy. It's an approach based on Lean and Agile principles, in which business managers, development, operations and quality assurance departments work together to deliver software continuously.
Why DevOps?
For many companies, going live is a difficult stage. The teams in charge often refuse to make rapid changes to the code because there are too many deliveries and deployments. The more new features there are, the longer it takes to put them into production, the more likely it is that there will be feedback on blocking elements, the more post-production tests will be needed, and so on. This can lead to downtime for the application, as well as stress for the teams and therefore money lost.
In the face of increasingly rapid change, DevOps is becoming essential for businesses that need to be agile enough to respond quickly to customer demands, market conditions, competitive pressures or regulations, and thereby increase customer satisfaction. The aim is to enable the company to seize market opportunities quickly and take account of customer feedback more rapidly. Enterprise applications are so complex that only a DevOps approach can successfully manage them. So it's vital to break down the barriers between developers and operational staff.
Conclusion
The DevOps movement aims to merge these two worlds by improving communication between them. DevOps aims to create a culture and environment in which software design, testing and delivery can be carried out quickly, frequently and efficiently.
Today, the wall between development and operations is gradually disappearing, because at the end of the day, these two poles are working towards a common goal.
