Abstract

Latency-sensitive artificial-intelligence services increasingly span heterogeneous edge and cloud resources, where static schedulers struggle with bursty arrivals, variable network conditions, and competing performance objectives. This paper presents an AI-native digital-twin framework for adaptive task placement across an edge-cloud continuum. A synchronized digital twin maintains the observed resource state and supplies a predicted workload descriptor to a Deep Q-Network scheduler. The scheduler selects feasible task-to-node assignments while balancing latency, operating cost, energy consumption, resource utilization, and service-level agreement violations. The evaluation uses workload patterns derived from Alibaba Cluster Trace and Microsoft Azure virtual-machine traces in a discrete-time simulator containing heterogeneous CPU- and GPU-capable nodes. The proposed method is compared with First-Come-First-Served, Round Robin, a capacity-aware heuristic, and a standard DQN without digital-twin prediction. Based on the simulation values supplied for this study, the proposed method reduces mean latency by 44.0% and energy use by 40.0% relative to FCFS under high load, while increasing throughput by 40.0% and reducing the SLA-violation rate from 25% to 8%. These findings indicate that predictive state augmentation can improve scheduling decisions during demanding workload conditions. The conclusions remain limited to trace-driven simulation; deployment-scale validation and independently reproducible code are therefore identified as necessary next steps.
