Supposedly a > $100mm deal. Both companies are already headquartered in N.C., and Ansible has a ton of momentum in the RHEL and OpenStack arenas, so it would make sense to pull the project into the fold. One thing I wonder is how much the project's priorities would shift away from (if at all) anything non-RHEL-centric.
Going by projects like NetworkManager it'll work okay, but you'll need to be a paying RedHat customer to get any useful documentation.
