Edge Computing Architectures for Ultra-Low Latency Applications

Abstract

The high rate of increase in the number of latency-sensitive services, including autonomous driving, remote surgery, augmented reality, industrial automation, and smart grids, has outlined the weaknesses of conventional cloud computing models. Although advantageous and scalable, centralized cloud data centers involve a high arguably serious latency because of network impacts, lengthy transmission paths, and delays while processing data. Edge computing has become a new paradigm that pulls the services of computation, storage, and intelligence back to the data source hence, allowing the creation of ultra-low latency services and real-time decision-making. This research paper is a detailed analysis of the edge computing architecture of ultra-low latency applications. The work explores the transformation of centralized cloud to distributed edge cloud ecosystems, examines key supporting technologies, 5G, software defined networking (SDN), network function virtualization (NFV), and containerized micro-services, and discusses such performance metrics as latency, throughput, reliability, and energy efficiency. It is being proposed that hierarchical edge computing architecture is based on integrating device edge, access edge, and regional edge layers in order to deploy them in a manner that is scaled and resilient. It is followed by the detailed literature survey analysis to evaluate the state-of-the-art architectures, schedule mechanisms, orchestration frameworks, as well as optimization techniques. In addition, there is also a methodological framework of the latency-aware task offloading, resource allocation, and service placement. The evaluation of the proposed architecture through analytical models and simulation-based evaluations shows that the proposed architecture can reduce the latency onto 65 percent of the time relative to the conventional cloud-based architecture. These findings affirm the claim that edge computing is an essential enabler of the next-generation applications that demand deterministic response time, high reliability and localized intelligence. A systematic architectural structure, performance discussion, and implementation of a guideline concerning the creation of subsequent ultra-low latency systems are presented in this paper.
