DevOps speeds up IT to achieve business agility. Compared with traditional IT, DevOps does the following:
Redefining teams to eliminate silos and barriers to progress (traditional silos being Business/Dev/QA/Ops)
Restructuring the approach to Release Planning—favoring small rapid releases to production over large groups of changes
Adopting agile and lean concepts across the entire end-to-end life cycle
DevOps maximizes automation across build, testing, provisioning, configuration management, promotion, deployment, and release stages.
