It is important to understand the basics +of a Triple-O deployment to help make decisions that will assist in +successfully deploying OPNFV. + +Triple-O stands for OpenStack On OpenStack. This means that OpenStack +will be used to install OpenStack. The target OPNFV deployment is an +OpenStack cloud with NFV features built-in that will be deployed by a +smaller all-in-one deployment of OpenStack. In this deployment +methodology there are two OpenStack installations. They are referred +to as the undercloud and the overcloud. The undercloud is used to +deploy the overcloud. + +The undercloud is the all-in-one installation of OpenStack that includes +baremetal provisioning. RDO Manager's deployment of the undercloud is +call Instack. Instack will be deployed as a virtual machine on a jumphost. +This VM is pre-built and distributed as part of the Apex RPM. + +The overcloud is OPNFV. Configuration will be passed into Instack and +Instack will use OpenStack's orchestration component call Heat to +execute a deployment will provision the target nodes to become OPNFV. |
