Creating a Multi-tier Architecture for Web Applications: Design and Implementation

Abstract

In today's world, where web applications are becoming more complex and diverse, the need for a layered architecture is particularly relevant. This architecture offers flexibility, scalability and ease of management, which is extremely important in the context of rapidly increasing requirements for information systems. Designing and implementing effective architectural solutions is becoming a crucial factor for the successful development and operation of web applications. Developers often face the limitations of a monolithic architecture, where every change in the code can unpredictably affect the entire system. This leads to difficulties in project management, difficulties in adding new features, and problems scaling the application. As a result, the risk of system failures increases and the rate of implementation of new features decreases. The study shows how a layered architecture can significantly reduce the dependency between system components, improve testability, and simplify the implementation of changes.
