Using the hosted Chef platform
If you want to get started with Chef right away (without the need to install your own Chef server) or want a third party to give you a Service Level Agreement (SLA) for your Chef server, you can sign up for hosted Chef by Chef Software, Inc. Chef Software, Inc. operates Chef as a cloud service. It's quick to set up and gives you full control, using users and groups to control the access permissions to your Chef setup. We'll configure knife, Chef's command-line tool to interact with hosted Chef, so that you can start managing your nodes.
Before being able to use hosted Chef, you need to sign up for the service. There is a free account for up to five nodes.
