 An extensible chatbot application, built with containers connected to a message queue.
 
 Japella's architecture splits out the connections to different protocols (eg Telegram, Discord) into "adaptor" services, and all bot functionality is implemented in a separate service, meaning that the chatbot functionality can easily work with new protocols, by just creating a new adaptor, or, can relay chat messages across protocols, for example.
