I am trying to figure out what is the recommended way to deploy Rasa in production
is it a good idea to deploy rasa_nlu and rasa_core with APIs interface at two different servers, assuming I need duckling also for some entity resolution? or I go with a rasa_nlu and rasa_core together and one duckling server?
what is more scalable and fail-safe architecture? I learned that rasa have moved from Flask to Klein which Application server is recommended for this in production?
