Quick Answer
DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to shorten the development lifecycle, increase deployment frequency, and deliver reliable software faster.
DevOps bridges the gap between writing code and running it in production. Traditionally, developers wrote code and threw it over the wall to an operations team that handled deployment, servers, and monitoring. DevOps eliminates this wall by making the same team responsible for building, deploying, and maintaining software.
Core DevOps Practices
Continuous Integration (CI) means developers merge code changes into a shared repository multiple times per day. Each merge triggers automated tests that catch bugs immediately.
Continuous Deployment (CD) automates the release process so that code changes that pass all tests are deployed to production automatically. See our CI/CD glossary entry for a deeper look.
Infrastructure as Code (IaC) defines server infrastructure using code files rather than manual configuration. Tools like Terraform and Pulumi make infrastructure reproducible, version-controlled, and auditable.
Monitoring and observability instruments applications to track performance, errors, and user behavior in production. Tools like Datadog, Grafana, and Sentry provide real-time dashboards and alerts.
Why DevOps Matters
DevOps practices directly correlate with higher software delivery performance, lower failure rates, and faster recovery from incidents.
