Choosing a service-oriented architecture for modern software applications provides a wide range of significant advantages that directly affect the quality, reliability, and sustainability of information systems. Among the key benefits of this architectural approach are simplified system maintenance, improved fault tolerance, increased reliability, accelerated development cycles, and enhanced flexibility of software solutions in response to changing business and technological requirements. By decomposing an application into independent services with clearly defined responsibilities and interfaces, service-oriented architecture enables teams to develop, deploy, and scale system components more efficiently and with lower operational risks. Despite its advantages, the implementation of a service-oriented architecture is associated with a number of challenges and potential issues. These include increased system complexity, difficulties in coordinating interactions between distributed services, latency in inter-service communication, and the need for reliable mechanisms to ensure data consistency and fault handling. Without proper architectural support, such systems may become difficult to manage, debug, and extend. The purpose of the work is to reveal the specifics of using event generation and processing mechanisms, which allow services to interact asynchronously and respond to changes in the system state in a timely and controlled manner. Experience with asynchronous and event-driven architectural approaches demonstrates that the application of well-established architectural patterns makes it possible to design software systems that operate smoothly even under high load and in dynamic execution environments. Event-based interaction models reduce tight coupling between services, enabling them to evolve independently and improving the overall resilience of the system. This approach also supports better scalability, as system components can be replicated or redistributed without significant changes to the core architecture. Furthermore, asynchronous service-oriented architectures provide favorable conditions for the incremental extension of system functionality. New services, business processes, or integration components can be added without disrupting existing system operations, which is particularly important in long-term software projects with evolving requirements. The use of standardized communication protocols, message brokers, and event generators ensures consistency, reliability, and transparency of interactions across the system. The results of the analysis confirm that the combination of service-oriented architecture principles with asynchronous event-driven mechanisms forms a robust foundation for building scalable, adaptable, and maintainable software applications. Such an architectural approach allows developers to balance system complexity with flexibility, ensuring high software quality and long-term effectiveness in rapidly changing technological environments.
