Designing Hexagonal Architectures for Scalable Web Services

Abstract

The design of scalable and maintainable web services is a critical aspect of modern software architecture, particularly when handling high traffic and evolving system requirements. Hexagonal architecture, also known as the Ports and Adapters pattern, offers a robust framework for structuring such systems. By isolating the core logic from external systems, this architecture ensures flexibility and scalability while allowing seamless integration with various external interfaces. The core idea of hexagonal architecture is to place the business logic in the center, with interfaces (ports) that interact with external systems (adapters) surrounding it. This design fosters modularity, enabling easier testing and maintenance, as well as promoting independent scalability of different components of the system.
