This paper dives deep into the architecture and implementation of an infrastructure for a nowcasting system. Its primary purpose is to display the various engineering and product trade offs while building such a system, as well as to provide an applicable system for a production use. The paper breaks down the initial stakeholder requirements and describes the system lifecycle from the design to the details of implementation. Among many different requirements, the one this paper focuses on the most is seamless client integration on both ends of the system. It uses REST API for integrating with the information producers, Kafka message queues for message networking and Websockets for data delivery to the consuming clients. The authors use empirical expert knowledge, in combination with thorough research to make well-informed decisions about how the system will function and fulfil its requirements. The end product is a high-throughput infrastructure written in Go, streaming over 300 messages/second, supporting over 40 concurrent clients (20 producing, 20 consuming), and achieving an average latency of 100 milliseconds for end-to-end message transfer with no message drops. Integrating with the system requires <20 LoC in any modern programming language (Python, Javascript, Java, Go…).
