MODEL FOR ORGANIZING HYBRID COMMUNICATION IN A MICROSERVICE ARCHITECTURE ON THE .NET PLATFORM

Abstract

Relevance. Modern microservice systems are widely used in high-load software products, particularly in cloud and enterprise environments, where performance, scalability, and reliability are critical requirements. The choice of interaction mechanisms between microservices significantly affects system behavior under load and its ability to handle peak request spikes. Object of research. The object of research is the interaction processes between microservices in distributed applications on the .NET platform. Purpose of the article. The purpose of the article is to analyze synchronous and asynchronous communication models, experimentally compare their performance under different load conditions, and substantiate a hybrid interaction model that combines the advantages of both approaches. Research results. Experimental performance testing of synchronous and asynchronous processing models was conducted. The results demonstrate that asynchronous interaction provides better scalability and resilience under high load, while the synchronous model is more effective for moderate traffic and low-latency scenarios. A hybrid model is proposed that dynamically selects the interaction type based on an integral load assessment. Conclusions. It is concluded that the use of a hybrid model enables stable and efficient operation of microservice systems by adaptively switching between synchronous and asynchronous processing depending on the current system state.
