DevOps

DevOps is a set of practices that bridges the gap between software development and IT operations. Rather than handing code over a wall to a separate ops team, DevOps culture makes both groups jointly responsible for building, deploying, and running the product. The goal is to shorten the feedback loop from commit to production while maintaining reliability.

Key technical pillars include infrastructure as code, containerization, continuous integration and delivery pipelines, and observability (logging, metrics, tracing). Tools like Docker and Kubernetes standardize packaging and orchestration, while Prometheus and Grafana provide the observability layer needed to operate services confidently at scale.

Culturally, DevOps emphasizes blameless postmortems, shared on-call rotations, and treating infrastructure definitions with the same rigor as application code — version-controlled, peer-reviewed, and tested. The DORA metrics — deployment frequency, lead time, change failure rate, and time to restore — are the standard benchmarks for measuring DevOps performance.
