Architectural Foundations and Performance Implications of Low-Latency Web APIs in Edge-Centric High-Transaction Mobile Systems

Abstract

The continuous evolution of mobile computing, augmented reality systems, and machine-type communications has intensified the demand for web architectures capable of sustaining extremely high transaction volumes under strict latency constraints. Contemporary applications such as mobile augmented reality, distributed crowdsensing, industrial automation, and massive machine-type communications require end-to-end responsiveness that traditional centralized cloud paradigms struggle to guarantee. This research article develops a comprehensive theoretical and methodological examination of low-latency web application programming interfaces deployed in high-transaction environments, with particular emphasis on edge computing, containerized infrastructures, and mobile network integration. Building upon recent benchmarking-oriented insights into low-latency web API design (Valiveti, 2025), the study situates web-layer optimizations within a broader socio-technical ecosystem involving mobile offloading architectures, edge standards, feedback-controlled container orchestration, and next-generation radio access technologies. Through an extensive qualitative methodology grounded in architectural reasoning and comparative literature analysis, the article interprets how latency-sensitive APIs interact with computation offloading, network scheduling, and decentralized execution models. The results highlight that latency minimization is not a property of isolated software components but an emergent outcome of tightly coupled design decisions spanning protocol layers, deployment topology, and adaptive control mechanisms. The discussion advances a critical synthesis of competing scholarly viewpoints, addressing tensions between standardization and innovation, centralization and decentralization, and determinism and adaptability. By articulating limitations inherent in current design approaches and proposing theoretically grounded directions for future research, this article contributes a holistic academic perspective on the role of low-latency web APIs as enabling infrastructures for next-generation mobile and edge-enabled systems.
