A company runs a real-time stock trading application where every millisecond of latency matters. The application ingests trades from an external feed, processes them, and updates the stock prices. The trading data is continuously ingested into Amazon Kinesis Data Streams, and the company needs to ensure low-latency processing of each record. The data is processed and then stored in Amazon RDS for real-time querying. The company wants to minimize operational complexity while ensuring that the system scales automatically with data volumes. Which architecture should be used to meet these requirements?
