Definition
DevOps is a cultural and technical movement that breaks down silos between software development (Dev) and IT operations (Ops). It combines practices, tools, and a cultural philosophy that increases an organization's ability to deliver applications and services at high velocity.
Key DevOps practices include: CI/CD, infrastructure as code, monitoring and observability, automated testing, containerization, and incident management. The goal is to shorten the development lifecycle while delivering features, fixes, and updates frequently and reliably.
DevOps has evolved into related disciplines: DevSecOps (integrating security), GitOps (Git as the single source of truth for infrastructure), and Platform Engineering (building internal developer platforms).
Why It Matters for Founders
DevOps practices are what enable modern software teams to ship quickly and reliably. Without DevOps, deployments are manual, infrastructure is fragile, and incidents take longer to resolve. With DevOps, teams can deploy multiple times per day with confidence.
For startups, adopting DevOps practices early creates a foundation for scaling. As the team and product grow, the automation and processes established by DevOps prevent the operational chaos that derails many growing companies.
