The Coffee Bar

Italian Bar with delicious coffee and cakes. Built using multiple technologies like NodeJS, Ruby, Python and .Net Core.

Based on data, order is passed to the-coffee-machine which is preparing coffee using machine-svc, coffee-svc and water-svc. All money transactions are handled by the-cashdesk service which is communicating with calculator-svc and postgres database.

All services are instrumented using OpenTelemetry solution.
