If anyone is wondering what the 'RDO' acronym stands for, from the FAQ[1]:
"RDO has no expansion or longer name, officially. It is not an acronym or abbreviation for anything.
However, RDO does focus on building a distribution of OpenStack specific to Red Hat operating systems (and clones of Red Hat operating systems). So, in some sense you can think of RDO as being a project started by Red Hat to build a distribution of OpenStack.
The 3 letter meaningless acronym sort of comes from that line of thinking."
Ansible is growing its OpenStack support, and they might see an opportunity for the RDO product.
