Scalable Resource Allocation for Cloud IaaS Using Energy Valley Algorithm

Abstract

Cloud computing stands as the dominant model which provides adjustable computing resources that automatically respond to user needs. Efficient resource allocation in cloud systems needs sophisticated algorithms to manage dynamic workloads with reduced power usage while achieving maximum resource utilization. This research work examines the performance of nature-inspired metaheuristic algorithms for Infrastructure-as-a-Service (IaaS) cloud resource allocation using the Energy Valley Optimizer (EVO). The study conducts its experiments through CloudSim which provides a powerful cloud simulation system to develop practical cloud computing systems. Two experimental settings consist of 5 virtual machines (VMs) and 10 VMs under varying workload sizes from 100 to 500 tasks to 1000–5000 tasks. Performance assessment includes execution duration together with power consumption measurements in kilowatt-hours (KWh) units and resource utilization percentage. The obtained results demonstrate that EVO provide superior performance through EVO’s 15% shorter execution time and 20–25% lower power usage than Symbiotic Organisms Search (SOS) and Particle Swarm Optimization (PSO) and Cuckoo Search (CSA)
