“…In comparison to many other policies, like, worst fit, best fit, and first fit, the new policy yields the best outcomes. Nevertheless, a policy is required to keep the ratio of power consumption to Modified Genetic algorithm EC Provide infeasible solutions [23] ML-based approach VM migration, SLA violation, and EC Does not consider the resource constraints [24] User needs-based approach EC, CPU utilization, and SLA violations High computational complexity [29] Energy-aware VM placement Energy, overload time fraction, VM migration, SL A violation Neglects traffic effects and network devices in its assessment [30] Hybrid VM allocation and placement EC, SLA Violation, VM migration Emphasize VM placement and host underload detection for performance enhancement…”
