Escalabilidade em Aplicações Web: Estudo de Caso em um Sistema Ruby on Rails

Abstract

Scalability is a desirable attribute of software systems, particularly on web applicati- ons, which may deal with large traffic spikes at any time. This work presents a case study on an application built using the Ruby on Rails framework. This study specifically targets a mailing list with customized content feature, which runs for more than 500.000 registe- red users. A new approach is suggested to implement that feature, thoroughly analyzing the nuances of each solution through metrics from performed experiments. Results show a significant decrease in resource consumption for the proposed solution. Future studies may perform experiments on multi-processor servers in order to see if further benefits can be observed on the suggested solution, due to its parallelizable nature.
