Distributed Tensorflow: ps/workers hosts on aws ?
When a distributed TF code is run on the cluster, other nodes could be accessed through "private ip: port number". 
But the problem with AWS is that the other nodes can not be easily launched and it needs extra configuration.
I am using distributed Tensorflow on aws using gpus. When I train the model on my local machine, I indicate ps_host/workers_host as something like 'localhost:2225'.  What are the ps/workers host I need to use in case of aws?
