This tutorial demonstrates how to create a reliable event streaming structure using Redis and Ably in Go programming language. The main components of the system include a trading server, which generates data on trades; a Redis container, which holds messages from the trading server; and an Ably publishing server, which consumes messages from Redis whenever it can publish to Ably. Clients are subscribed to the Ably channel that the Publisher publishes to and displays the information. The stack also includes Docker for creating Images and Kubernetes for managing a collection of Docker Containers.
