Reinforcement Learning for Server-Aware Offloading in Multi-Tier Multi-Instance Computing Architecture
Task offloading in distributed computing involves complex trade-offs among delay, scalability, cost, and resource utilization. Cloud platforms face long communication delays, while edge nodes have constrained capacity. Static, rule-based schedulers cannot adapt to fluctuating loads or per-instance heterogeneity. Reinforcement Learning (RL) schemes typically address only a single layer or assume homogeneous servers. This paper introduces a server-aware Proximal Policy Optimization (PPO) framework for fine-grained offloading across a three-tier (Edge, Regional, Cloud), multi-instance architecture. Offloading is formulated as a Markov Decision Process whose state vector includes per-instance delay, CPU/memory utilization, network congestion, cost, and energy metrics. The PPO agent learns to offload tasks to the best server in real time.
Executive Impact & Key Metrics
The developed RegionalEdgeSimPy simulation demonstrates that the PPO agent makes optimal offloading choices for over 90% of tasks, keeping each server near, however, below 70% utilization. This optimized decision making drives up to 66.9% delay reduction, 78.6% energy savings, and 47.8% cost reductions relative to cloud-only and edge-only baselines.

Overview of Multi-Tier Computing
The emergence of IoT has transformed data, requiring mass processing and low latency. Cloud computing offers scalability but suffers from long communication delays. Edge computing brings resources closer, reducing delay. Multi-tier architectures (Edge, Regional, Cloud) offer layered systems to balance delay, energy, and capacity.
Reinforcement Learning for Optimal Offloading
Reinforcement Learning (RL) is a promising alternative for intelligent task offloading in dynamic and heterogeneous computation environments. RL frameworks learn optimal policies by exploring the environment and adapting decisions based on system states and reward feedback. The offloading choice is formulated as a Markov Decision Process (MDP), where the agent learns to maximize long-term utility across multiple performance metrics.

This study introduces a server-aware Proximal Policy Optimization (PPO) framework for fine-grained offloading across a three-tier (Edge, Regional, Cloud), multi-instance architecture. The offloading is formulated as a Markov Decision Process (MDP) whose state vector includes per-instance delay, CPU/memory utilization, network congestion, cost, and energy metrics. The PPO agent learns to offload tasks to the best server in real time, showing optimal choices for over 90% of tasks and significant reductions in delay, energy, and cost.
Simulation Validation & Performance
The developed RegionalEdgeSimPy simulation shows that the PPO agent makes optimal offloading choices for over 90% of tasks, keeping each server below 70% utilization. This leads to up to 66.9% delay reduction, 78.6% energy savings, and 47.8% cost reductions relative to cloud-only and edge-only baselines. The simulation validates the efficiency of the tier-aware scheduling policy in ensuring processing balance and resource utilization.

Optimized Multi-Tier Resource Utilization
The simulation results consistently demonstrate the scheduler's ability to maintain balanced CPU, memory, and storage utilization across Edge, Regional, and Cloud tiers. Tasks are dynamically redirected to higher tiers only when lower tiers approach defined utilization thresholds, ensuring efficient resource allocation and preventing overload.
Edge servers prioritize delay-sensitive tasks, offloading to Regional and Cloud tiers for capacity, preventing bottlenecks and ensuring stable performance even under increasing device loads.
