Simple realtime notifications

Guide for realtime notifications through SaaS

• Our Backend has microservices architecture with a message bus for communication between services
• We have many services in Backend, but only two are important for this example: Orders and Events
• Backend services are written in everything from Cobol to Go, but for events we want something simple and reasonable like Python
• We want some free SaaS like Pusher to handle realtime notification complexity for us…
