DevOps is a set of practices that automates the processes between software development and IT teams, in order to build, test, and release software faster and more reliably. It’s a cultural shift and a methodology, not just a specific tool.

DevOps Engineer

1. What It Is

A DevOps Engineer bridges the gap between development and operations teams. They automate and streamline the software development lifecycle (SDLC) from code commit to deployment and monitoring. They focus on continuous integration, continuous delivery (CI/CD), and infrastructure as code. Key difference from other roles: Focuses on process automation and collaboration, not specific coding tasks.

2. Where It Fits in the Ecosystem

DevOps Engineers work across the entire SDLC. They collaborate with developers, testers, and operations teams to ensure efficient and reliable software releases. They touch both development and operations environments.
