Architecture

• A Python webapp which lets you vote between two options
• A Redis queue which collects new votes
• A Python worker (designed for lambda) which consumes votes and stores them in…
• A Postgres database backed by a Docker volume
• A Node.js 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.
