Reducing Inter-Service Communication Latency in Microservices

Inter-service communication latency is one of the major challenges in the architecture of microservices-based systems. It affects the system's responsiveness and user experience. The factors that contribute to such latency include protocol overhead, network dynamics, and server overload. In this research, various strategies to address these challenges are evaluated. Techniques include protocol optimization using gRPC, reducing redundant data retrieval by means of distributed caching, and adaptive load-balancing algorithms for even workload distribution. Circuit breakers and bulkheads are also assessed with the fault-tolerant pattern in terms of the potential to maintain performance when things go wrong. It appears that reducing latency will take more than just an array of tools, a good monitoring framework, and proactive optimization techniques to really help organizations realize improvements in the scalability and reliability of their microservices-based systems. This study concludes with actionable recommendations and identifies future research opportunities in the utilization of emerging technologies towards further optimization.
