Although they had complementary work, both departments ended up isolated in their own tasks and objectives, making it difficult to update software quickly and safely.
The alignment between sectors emerged in the wake of agile development , employing a series of tools and, in particular, dynamics that would overcome the barriers between Dev (developers) and Ops (operators).

What is DevOps?
DevOps is a culture based on practices, models and integrative tools , which allow the elimination of walls between two types of professionals working in software engineering – developers and operators.
Its purpose is to maintain a complementary and constant work pace, which meets the frequent demand for updates to complex systems in today’s organizations.
Anyone who works in the IT department or close to it, knows that the processes and responsibilities of the development and operational management teams ended up distancing these professionals, even encouraging a certain rivalry between them.
While developers work to deliver value to the user , contemplating their needs through different functionalities, operators are concerned with the stability of the software.
As already highlighted in the opening of this text, the functions end up complementing each other.
However, the specialists who perform them spoke little to optimize the tasks and obtain a more aligned result.
However, with the emergence of software with multiple features and the need for continuous adaptation, this problem needed to be resolved, and the solution found was the DevOps concept.
Inspired by the agile development movement, it proved to be effective in bringing the two categories of professionals together, adopting premises of simplification and standardization of interfaces.
Remembering that agile development presupposes the construction of software in a collaborative way, betting on the commitment of multidisciplinary teams .
This model is opposed to traditional development, in which processes were executed in a cascade, that is, a step could only start when another was completed.
According to the Agile Manifesto , a document that made the set of agile methodologies official , the secret lies in valuing:
- Individuals and interactions more than processes and tools
- Software at work more than comprehensive documentation
- Collaboration with the client more than negotiating contracts
- Responding to changes is more than following a plan.
When and how did DevOps come about?
Before talking about the context in which this culture was created, it is worth clarifying the meaning of the term DevOps, which represents the abbreviated form of the words development (Dev) and operations (Ops) .
As might be expected, development means development, and operations, operations, in a clear reference to the indispensable sectors for software engineering.
Now, let’s go into the history of this concept.
We have already mentioned, above, that it was inspired by movements such as agile development, which was born in 2001 and proposed the continuous and simplified improvement of systems.
Well, eight years later, IT professionals gathered at an event called the Velocity Conference .
Among other lectures, they attended the presentation “10+ Deploys Per Day: Dev and Ops Cooperation at Flickr”, given by John Allspaw and Paul Hammond .
The idea of the lecture was to show how cooperation made a difference in the routine of the IT team at Flickr, a hosting and image sharing site, with benefits for developers, operators and, above all, for the user.
Among the seminar’s online audience was operations administrator Patrick Debois , who was already studying ways to bridge the divide between development and operations and ended up joining the initials of the words to coin the term DevOps.
The search for efficiency was present since the beginning of this movement, which began to be disseminated through events called “ DevOps Days ” in countries such as Belgium, Australia, Brazil, Sweden, among others.
What is DevOps for?
DevOps serves to unify the development and operations administration teams, providing shortcuts to improve the quality of the product , that is, the software.
When this unit does not exist, the tendency is for the two sectors to walk separately, which increases the chances of bugs, delays and misalignment in deliveries, reducing the efficiency of the programs.
The fluidity proposed by the DevOps philosophy makes it possible to meet the market’s increasingly fast demands , supplying the need for robust updates in an intelligent way.
