Abstract
This research paper explores the challenges and solutions in distributed microservice development. Microservices architecture, which structures applications as collections of loosely coupled services, offers significant advantages over traditional monolithic systems, including enhanced scalability, flexibility, and rapid deployment. However, this architectural style introduces complexities in service communication, data management, and deployment. Key challenges identified include defining service boundaries, ensuring data consistency and integrity, managing inter-service communication, and implementing dynamic service discovery and load balancing. The paper discusses potential solutions such as event sourcing, CQRS, service mesh technologies, and robust security mechanisms to address these challenges. Additionally, it highlights the importance of appropriate tooling, continuous integration and continuous deployment (CI/CD) pipelines, and choosing suitable communication protocols and data management strategies. By addressing these challenges, organizations can fully leverage the benefits of microservices to build scalable, resilient, and flexible applications.
