Gautam Solaimalai . Serverless Architecture for Real-Time Stock Market Data Analytics in Cloud Environments. International Journal of Computer Applications. 186, 75 ( Mar 2025), 9-15. DOI=10.5120/ijca2025924625
The methodology established in this paper presents AWS Lambda and DynamoDB to deliver continuous statistics on stock market data processing and the related analytics. This method is particularly economical, dynamic, and low latency due in part to the design's ability to include additional consumers to "scale up" or "scale down" depending on the incoming high-frequency trade supports. AWS Lambda functions can read and analyze box data that are constructed in a DynamoDB data table by processing incoming real-time data with calling financial APIs functions first. When running through predictive analytical models, some potential results could include LSTM (Long Short-Term Memory) and other ML models. While we outline improvements over existing systems, all of our results show a marginal impact on improvements demonstrated through improvements in our overall delay of 3% in the end-to-end processing time, 1% in pre-processing the input data across AWS Lambda, and 1% in processing time in total. We achieved a latency of around 150 ms and can handle 1000 requests concurrently, with resulting efficiency in scaling 95%. Other, significant features include fault recovery time in about 300 ms and a failure rate of 0.5%, which are indications of the fault tolerance of this design. This format brings a scalable and effective solution to financial market analytics, as it effectively employs a distributed microservices design into modern financial infrastructure, which are key to the high-volume processing involved in stock market data analytics.
