To support SEO tatctics I have added a glossary of terms. The
terms the terms added are: kubernetes, lifecycle management,
orchestration, openstack ironic (OpenStack bare metal provisioning),
bare metal, provisioning Openstack ironic, container orchestration
platform, network function virtualization infrastructure, and
software defined networking (sdn). A full list of terms and
definitions can be found here:
