TEMPORAL COUPLING AND DATA CONSISTENCY CHALLENGES IN SYNCHRONOUS VERSUS ASYNCHRONOUS MICROSERVICES COMMUNICATION
Keywords:
Microservices, Temporal Coupling, Data Consistency, Synchronous Communication, Asynchronous Messaging, Event-driven Architecture, CAP TheoremSynopsis
Modern microservices-based systems require robust communication models to ensure responsiveness, scalability, and data consistency. Synchronous and asynchronous communication models each bring distinct trade-offs. This paper investigates the challenges of temporal coupling and data consistency in both models. We use a combination of literature analysis, data tables, and diagrams to show how communication mechanisms impact service decoupling, latency, and consistency. Empirical insights from previous studies are synthesized into a comparative framework to aid architectural decision-making.
