AWS OpsWorks for Chef Automate Features
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.
