What is DevOps?

DevOps is a set of cultural practices and automation that unites software development and IT operations, so teams share ownership of building, releasing and running software and can ship changes quickly and reliably.

Definition: DevOps is a set of cultural practices and automation that unites software development and IT operations, so teams share ownership of building, releasing and running software and can ship changes quickly and reliably.

Core practices

Continuous integration and delivery, automated testing, infrastructure as code, monitoring and alerting, frequent incremental releases, and blameless reviews after incidents.

How DevOps is measured

The DORA research program popularized four delivery metrics: deployment frequency, lead time for changes, change failure rate and time to restore service. Together they balance speed against stability.

Related disciplines

Site reliability engineering applies software engineering to operations with service-level objectives and error budgets. Platform engineering packages DevOps tooling as a self-service internal product. MLOps and LLMOps extend the same ideas to models.

Common mistakes

Renaming an operations team "DevOps" without changing ownership, automating a broken process, or adopting tools without the testing culture that makes fast releases safe.
