What is DevOps?

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It aims to shorten the development lifecycle and deliver high-quality software continuously. Key pillars include automation, continuous integration/delivery,infrastructure as code, monitoring, and collaboration.

In practice, DevOps engineers work with tools like Docker (containers), Kubernetes (orchestration), Terraform (infrastructure), GitHub Actions (CI/CD), and Prometheus (monitoring) to build reliable, scalable systems.
