Hi ermintrude, Ansible has lots of parallelism support. From --forks, where you can specify parallelism on the push (Rackspace does this to configure 10k nodes at once in production), to ansible-pull (massive scale out), to the provisioning callback feature in AWX that is just perfect for AWS autoscaling, all of that is definitely there. If you're talking about multiple parallel playbooks, just launch two playbooks at once, and you can use things like wait_for to hold out for arbitrary conditions.
