Chef is an automation patform that helps you automate operational tasks at scale. You can use Chef to manage both Amazon Elastic Compute Cloud (Amazon EC2) instances and on-premises servers running Linux or Windows.

With Chef, you use code templates, or cookbooks, to describe the desired configuration of instances or on-premises servers. Cookbooks contain recipes that describe the desired state for a configuration item and the steps needed to reach that state, server settings, information on how to distribute files, and more. You can use cookbooks to automate operational tasks such as configuring hosts and applications, installing packages, shutting down instances, and more. You can author your own cookbooks or use over 3,000 publicly available cookbooks from the Chef community.

How Chef Server Works

The Chef server acts as the hub for configuration data and distributes information about desired configurations to nodes. It stores your cookbooks, the policies that are applied to nodes, and metadata that describes each registered node that is being managed by Chef. Nodes are instances or on-premises servers running the Chef client. Each node registered to the Chef server regularly executes the policies stored on the Chef server to converge your instances and servers to their desired state.

The Chef server coordinates complex operational tasks to keep your instance configurations consistent. It handles interdependencies such as multiple database replicas that need to be synchronized. Chef server is also fault-tolerant because most of the configuration work is distributed to the nodes themselves, which periodically initiate contact with Chef server. This distributed approach also means that nodes which unexpectedly go offline or reboot are able to automatically return to the desired state after coming back online.
