A typical ticketing system that is designed for micro services environment with highly scalable and concurrent needs.
Kiosk designed by scalability and ease of use in mind, so we chose nats as message bus because of its modern distributed patterns. Every kiosk node listens to all subjects but in queue grouped manner, so the requests will distribute between different nodes. The message protocol is typical JSON format, so it can be used by all nats clients.
For more information about subject names and request/response models see Wiki pages.
