Let's explore the history of DevOps in this 'Introduction to DevOps' guide. DevOps emerged due to the increasing necessity for agility in IT operations and software development. It can be traced back to the beginning of the 2000s. This is when software development methodologies such as Agile began to emphasize iterative development and collaboration. The disconnect prevalent between operations and development teams often resulted in operational inefficiencies and slow releases.
The term DevOps first became popularized in 2009. It was Patrick Debois who was behind the organizing of the first ever DevOpsDays conference held in Ghent, Belgium. This particular event resulted in operations professionals and developers coming together. They discussed the challenges faced by a company due to siloed teams, emphasizing on the imperatives for a more integrated approach.
The evolution of DevOps has witnessed some key growth points.
Before DevOps came into the picture, the development and operations scene was usually characterized by inefficiencies and silos. These teams generally worked in isolation, which led to a disconnect, hindering productivity and collaboration.
- Waterfall Methodology: Most of the teams followed the Waterfall model. Here, development phases occurred in a sequence. It was a rigid process that made it difficult to adjust to the changes. Hence, it led to lengthy development cycles.
- Delayed Feedback: Since developers had very limited interaction with operations, delayed feedback was quite common. This led to late discovery of bugs and issues, which made the process costlier and more time-consuming.
