Chef
Chef is a tool that helps IT teams set up and manage computer systems automatically. Think of it like a recipe book for computers - just as a chef follows a recipe to cook a meal, this software follows instructions to set up servers and applications consistently. Instead of manually installing and configuring software on each computer, Chef allows technology teams to write simple instructions once and apply them to hundreds or thousands of computers automatically. This type of tool is known as "infrastructure automation" or "configuration management" software. Similar tools include Puppet and Ansible.
