This work aims to compare three software architectures — monolithic, client-server, and serverless — applied to the same real system: Open Social Care, an application focused on managing social initiatives. The choice of architectures is justified by the need to understand, in practice, the technical and operational implications of each model in the development and deployment of web systems. The adopted methodology involved fully implementation the system in each of the architectures, followed by experiments in controlled environments. Aspects such as performance, resource consumption, response time, developer experience, ease of deployment, and infrastructure costs were analyzed. The results indicated that the monolithic architecture offers greater simplicity and lower operational cost, being recommended for MVPs and small-scale projects, and may also support larger applications through vertical scalability. The client-server architecture, although requiring greater configuration and maintenance effort, stands out for its modularity and organization, making it suitable for expanding systems. The serverless architecture showed the best response times and the least deployment effort, along with automatic scalability, making it suitable for applications with fluctuating demand. However, its costs can become disadvantageous as the application grows, requiring constant monitoring. The critical analysis highlighted that there is no universally superior architecture, but rather different solutions that are more appropriate depending on the context, team resources, and system characteristics. The study concludes that serverless architecture is currently the most advantageous for the analyzed application, with a recommendation for future migration to client-server architecture if project growth justifies it. This work contributes to the practical understanding of architectural decisions and their impact on the life cycle of modern web systems.
