Magnum interacts with Heat to do the orchestration. This means Heat is the OpenStack component that talks to various other projects such as Nova, Neutron, and Cinder to set up the infrastructure for COE, and then it installs the COE on top of it. We will now learn about the detailed functions of the services.
