IMPLEMENTING MICROSERVICES ARCHITECTURE: TECHNICAL CHALLENGES AND SOLUTIONS

Abstract

This paper examines the technical challenges faced by organizations and developers during the implementation of microservices architecture and offers solutions to overcome them. It focuses on key aspects such as service decomposition, inter-service communication, security assurance, and data management in distributed systems. Domain-Driven Design is identified as a critical strategy for segmenting monolithic applications into business-oriented microservices, thereby enhancing the system's maintainability and scalability. The discussion on inter-service communication reveals trade-offs between synchronous and asynchronous methods, noting that while synchronous communication provides immediate feedback, it can lead to delays and potential failures. In contrast, asynchronous strategies improve resilience, scalability, and loose coupling but introduce additional complexity. The research also explores security mechanisms, emphasizing the role of Single Sign-On and API Gateway in simplifying access control and enhancing security in microservice architectures. Furthermore, the paper provides recommendations for addressing the challenges of distributed data management, advocating for event-driven replication and the Saga pattern to ensure data consistency across services, alongside the use of GraphQL, API Gateway, and the CQRS pattern for efficient data aggregation and retrieval. By examining these aspects, the paper underscores the critical importance of a strategic and informed approach to implementing microservices, emphasizing the need to understand the implications of each architectural option for building resilient, scalable, and adaptive software systems.
