Yes, Ansible is very often used within CloudCenter. An example would be that a team has a working Ansible Playbook to install a software component but needs more features which CloudCenter can provide - cloud abstraction for the software service, governance, cost management, ITSM integration, leverage other existing services within CloudCenter (LBs, FWs, related services), etc. This type of use means removing the prescriptive infrastructure configuration commands that CloudCenter will handle for all clouds and breaking the Ansible playbook down into more granular functions that correspond to the CloudCenter lifecycle actions and then using ansible pull commands as the command for the lifecycle action rather than a local CloudCenter command or repo script.
There are other ways to integrate easily with Ansible as well but this is one of the most commonly used ways by CloudCenter users.
