VM Scheduling for Efficient Dynamically Migrated Virtual Machines (VMS-EDMVM) in Cloud Computing Environment

Abstract

With the massive demand and growth of cloud computing, virtualization plays an important role in providing services to end-users efficiently. However, with the increase in services over Cloud Computing, it is becoming more challenging to manage and run multiple Virtual Machines (VMs) in Cloud Computing because of excessive power consumption. It is thus important to overcome these challenges by adopting an efficient technique to manage and monitor the status of VMs in a cloud environment. Reduction of power/energy consumption can be done by managing VMs more effectively in the datacenters of the cloud environment by switching between the active and inactive states of a VM. As a result, energy consumption reduces carbon emissions, leading to green cloud computing. The proposed Efficient Dynamic VM Scheduling approach minimizes Service Level Agreement (SLA) violations and manages VM migration by lowering the energy consumption effectively along with the balanced load. In the proposed work, VM Scheduling for Efficient Dynamically Migrated VM (VMS-EDMVM) approach first detects the over-utilized host using the Modified Weighted Linear Regression (MWLR) algorithm and along with the dynamic utilization model for an underutilized host. Maximum Power Reduction and Reduced Time (MPRRT) approach has been developed for the VM selection followed by a two-phase Best-Fit CPU, BW (BFCB) VM Scheduling mechanism which is simulated in CloudSim based on the adaptive utilization threshold base. The proposed work achieved a Power consumption of 108.45 kWh, and the total SLA violation was 0.1%. The VM migration count was reduced to 2,202 times, revealing better performance as compared to other methods mentioned in this paper.

I5 Framework: Institutions-Industries-Interactions Innovations-Incubators for Strengthening Start-up Ecosystem in Higher Education Institutions

“…In this way, if the HEIs can focus on I5 framework, we can see the massive success of HEIs and startups. By efficiently assigning the necessary virtual resources [15,16,19,20,21], the current work can be extended to Cloud Computing apps by allowing massive data processing and numerous users to access it.…”

A Review on Efficient Energy Consumption in Software-Defined Networking Using Routing Aware Protocols

“…In [58], [59]recommended a Smooth EAR (SENAtoR) for guaranteeing EAR in a circumstance of progressive migration as of legacy to SDN hardware. SENAtoR offered enormous characteristics to securely guarantee ES services like smooth node disabling, tunneling for fast rerouting along with detection of traffic spikes and link failures; while normally, turning off-network appliances was a fragile task since it led to packet losses.…”

Machine Learning Centered Energy Optimization In Cloud Computing: A Review

“…This technique enables CPUs to run at various combinations of clock frequencies and voltages based on system performance requirements at a given time [9]. Consolidation refers to the live migration of virtual machines from one host to another with minimum execution-related delays [10 the voltage and frequency automatically to cut down on CPU heat generation and power consumption. Furthermore, less heat generated enables cooling systems to be switched off while saving more energy [9].…”
