What is DevOps?
A culture and practice combining software development and IT operations for faster, reliable delivery.
DevOps is a set of practices, tools, and cultural philosophy that automates and integrates the work of software development and IT operations teams. The goal is shorter development cycles, more frequent deployments, and more reliable releases. Core DevOps practices include CI/CD, Infrastructure as Code, monitoring and observability, and blameless postmortems. DevOps is not a job title — it's an organizational approach.
