Hi, Andy I found that OSA use keepalived to resolve controller HA, but whether the keepalived support compute HA? What shoud I do or which file I need to config if I want to resolve compute HA?
And there are some solutions for compute HA in this web: http://aspiers.github.io/openstack-summit-2016-austin-compute-ha/ . Would the OSA use pacemaker or some other solutions to support compute HA?

OSA can install haproxy, but I can not found any other HA solution in openstack-ansible-haproxy_server, like keepalived or pacemarker. So how to making HAproxy high-available? Take a look at: https://docs.openstack.org/developer/openstack-ansible-haproxy_server/configure-haproxy.html#making-haproxy-highly-available that will give you some direction on how to set that up! 2. Could OSA support compute node high available? If my compute node down, could the instance on this node move to other nodes? This wouldn't specifically be OSA as such - the configuration side of it could be set up by OSA, such as configuration options, shared storage required. However the automatic evacuation of instances, or migration of instances wouldn't be handled by OSA or anything that OSA deploys. I hope that helps! If you have any more questions, or need further help getting set up with OSA feel free to drop by the #openstack-ansible channel on Freenode IRC. Thanks! Andy
