> Chef Infra is a powerful automation platform that transforms infrastructure into code. Whether you’re operating in the cloud, on-premises, or in a hybrid environment, Chef Infra automates how infrastructure is configured, deployed, and managed across your network, no matter its size.

In an imprecise nutshell: You specify what needs to exist on the target system using Chef's DSL and Chef client will converge the state of the target to the desired one.
