The decision to use monolithic architecture for a Spring Boot web application with only a few pages (less than 5) is a common debate. However, I argue that the benefits of a monolithic architecture outweigh the drawbacks. Firstly, the maintenance cost is significantly reduced without the need for a separate gateway to handle requests from the frontend and backend. This eliminates the complexity of managing multiple microservices and integrating them with a gateway. Additionally, the absence of a gateway reduces the overhead of serializing and deserializing data, leading to faster response times and improved performance. Furthermore, the lack of dependency on frontend frameworks such as React or Vue reduces the size of the JavaScript files, resulting in faster loading times. Moreover, a monolithic architecture is easier to understand and maintain, as there is no need to navigate complex communication channels between microservices. In conclusion, a monolithic architecture is a suitable choice for a Spring Boot web application with a limited number of pages, offering improved performance, faster response times, and easier maintenance.
