Data center networks are complex beasts. Network engineers approach data center operations and management with caution because even the smallest change can result in unintended outcomes, including performance degradation, security holes, policy violations, and downtime.

Organizations often make changes manually, device by device. This approach slows down the deployment of new applications and hampers agility. It can also create new problems by increasing the likelihood of human error through misconfiguration or keyboarding mistakes. And basic automation techniques such as scripting lack formal validation, which can compound human error.
