Example Voting App

A simple distributed application running across multiple Docker containers.

Architecture

• A front-end web app in Python or ASP.NET Core which lets you vote between two options
• A Redis or NATS queue which collects new votes
• A .NET Core, Java or .NET Core 2.1 worker which consumes votes and stores them in…
• A Postgres or TiDB database backed by a Docker volume
• A Node.js or ASP.NET Core SignalR webapp which shows the results of the voting in real time

Note

The voting application only accepts one vote per client. It does not register votes if a vote has already been submitted from a client.
