Hi, Is it the case that there are basically 2 ways to deploy a neutron api server? One way is to deploy it via wsgi/apache, which requires deploying another neutron-rpc-server process along with it; Another way is to deploy it as standalone (without the help of wsgi/apache), with 'rpc_worker' parameter configured, so that rpc worker would run alongside with api worker process. If so, what are the pros and cons for them? Did not find much Openstack neutron documentation on this topic thus far. - Hai
