What is DevOps? Understanding the Fundamental Concept
DevOps is a revolutionary methodology that combines development (Dev) and operations (Ops) to create a more efficient and collaborative software lifecycle. But what exactly does DevOps mean?
In simple terms, DevOps is a culture, philosophy, and set of practices that aims to break down the traditional barriers between development teams and IT operations. This integrated approach enables faster deliveries, higher quality, and better collaboration between teams.
DevOps: What Does It Mean in Practice?
When we ask “what does DevOps mean ,” we’re talking about:
