Low-Latency Architecture Patterns for Large-Scale Android E-commerce Platforms

The greater volume and complexity of e-commerce applications based on Android has worsened the need for an ultra-low latency system architecture. This analysis considers key architectural styles—REST, gRPC, and Edge-Aware design—used in large mobile commerce companies. Experimental results, based on 10,000 concurrent request simulations, show that integration of edge computing and binary communication protocols results in dramatic decreases in the average and peak load latency, memory usage, and request failure rates. Notably, the edge-aware design achieves superior performance in both cold start initialization and steady-state request handling due to its localized processing and adaptive routing. The architectural trade-offs and optimization pathways to enable scalable, high-performance e-commerce delivery are emphasized by the analysis. The article ends with directions for future research that revolve around adaptive orchestration, architecture tuning with the use of ML, and resilient design in the context of real-world network operation.
