Integrated Green Cloud Framework using Virtualization, Carbon-Aware Workload Migration, and Simulation for Sustainable Data Centers.

The unforeseen growth of digital services has escalated energy requirements in the world data centers, and an environmental sustainability issue is a hot topic in cloud computing. Conventional parallelism to workload scheduling fails to consider real time carbon intensity and regional grid efficiency thus resulting in high carbon emission even in optimally performed computational work. The proposed work suggests a green cloud synergetic framework, which integrates the virtualization, the carbon-aware workload migration, and the simulation-based decision model to plain the challenge of energy inefficiency and the environmental impact associated with the data center operations. This framework exploits a dynamic virtualization layer to achieve VM consolidation, as well as a carbon-conscious migrator that on real-time emissions data migrates workloads to utilise cleaner regional grids. CloudSim Plus-supported simulation environment was created to test the model in terms of its operation over the 24-hour period, with the testing against baseline and partial setup. The findings show the decreased energy usage of 36.6 percent and a decreased carbon emission of 52 percent in comparison with the conventional static allocation plan. The added migration events do not affect significantly the model as it continues to sustain high VM utilization (72.3%) and low SLA violations (8.1%). The effectiveness of the proposed framework compared to the available scheduling models is proven by the matter of fact that the former performs better in terms of various tracks of sustainability according to benchmarking. The paper presents a flexible and elastic approach to a sustainable cloud infrastructure and forms the basis of future-generation carbon-minded orchestration in the cloud.
