Arquitetura serverless distribuída para análise do preço do dólar

Abstract

This work presents the development of a distributed serverless architecture for real-time analysis of the US dollar exchange rate, using AWS services. The proposed architecture leverages AWS Lambda for automation and scalability, Amazon EventBridge for data collection scheduling, and DynamoDB for storage. The FreeCurrConv API was used as the source for currency data, and automatic notifications were configured via Amazon SES. Experiments demonstrated that the system can automatically scale, maintaining consistent response times even under high request loads. However, the API’s limitation on the number of requests per minute highlighted the need for more robust alternatives in high-demand applications. The study concludes that the serverless architecture is an efficient, scalable, and cost-effective solution for real-time currency monitoring, with room for future improvements and expansion.
