run docker compose upd -d --build to run kafka broker

Summary of what each microservice will do

• data_receiver

Will receive data through websocket connection and produce calculated distance to Kafka

• Listen to the socket for receiving data
• Validate encoming request
• Produce to kafka

• distance_calculator

Will consume data from kafka, and calculate toll price and send it to aggregator microservice using HTTP or gRPC clients

• Consume to obudata topic
• Calculate distance for the obu
• Send calculated distance to aggregator service using gRPC or HTTP clients

• aggregator

Will receive, aggregate and return invoices for OBUs

• Will aggregate invoices via gRPC and HTTP
• Will process, calculate and return invoice for an OBU

• gateway

Gate way to interact with microservices

• Has /invoice endpoint, which will get an OBU id
• Will get invoice for entered OBU from the aggregator service using gRPC or HTTP client
• Return invoice to user
