DevOps is a set of practices and a collaborative approach that brings together software development (Dev) and IT operations (Ops) teams to improve the speed, quality, and reliability of software delivery. It focuses on automation, continuous integration and continuous delivery (CI/CD), system monitoring, and efficient infrastructure management to ensure smooth application releases.
The role of a DevOps Engineer is to support the entire software development lifecycle by automating deployment processes, managing cloud and on-premise infrastructure, and maintaining reliable and secure systems. DevOps Engineers work closely with developers, testers, and operations teams to streamline workflows, reduce deployment failures, and improve system performance.
Key responsibilities often include setting up and maintaining CI/CD pipelines, monitoring applications and servers, managing configuration and infrastructure as code, and quickly identifying and resolving production issues. The role also involves improving scalability, enhancing security practices, and ensuring high availability of applications.
Overall, a DevOps Engineer helps organizations deliver software faster, operate systems more efficiently, and provide a better experience for end users by bridging the gap between development and operations teams.
