Green cloud computing makes it possible to maintain and enhance business operations and processes while looking after the environment.
III. ARCHITECTURE OF GREEN CLOUD COMPUTING
Consumers / Brokers: It is the submit the collect service requests from anywhere in the world to the cloud. It is very important to notice that there can be a difference between cloud consumers and users of deployed services. For instance, a consumer can be a company deploying a web application, which presents varying workload according to the number of users assessing it.
Green Resource Allocator: It is act as the interface between the cloud infrastructure and consumers. It requires the interaction to support energy efficient resource management.
Virtual Machines: It can be dynamically started and stopped on a signal physical machine to meet accepted requests, hence it providing maximum flexibility to configure various partitions of resources on the same physical machine to different specific requirements of service request.
Physical Machine: It creating virtualized resources to meet service demands by providing hardware infrastructure of underlaying physical computing servers.
IV. TECHNIQUES TO MAKE THE CLOUD “GREEN”
Revolutionize the future of green cloud computing has three techniques
A. Nano Data Centers
Nano Data Centers are more energy efficient than other conventional data centers.Nano Data Centers helps to reduce the cost of heat dissipation, they have high service proximity. They have the capacity for self adaption and scalability.
B. Dynamic Voltage Frequency Scaling
It is the method which reduces energy consumption process and power used with frequency scaling.By implementing this technique it will reduce energy consumption and leverage the utilization of the resource.
Virtualization is a technique that improves machine management and energy efficiency through sharing a single physical instance of a resource and application with multiple customers or organization the same time.In an eco friendly way virtulization maximize the number of available system resources.
V. IMPACTS OF GREEN CLOUD COMPUTING
A. Fewer Carbon Footprints Because Of Remote Workers
Cloud computing permits businesses to collect their data on the internet, which means it can be obtained by anyone given the authority, no matter the location or whatever device is being used. This opportunity given by businesses and companies the flexibility to gear their employees toward remote working. By practicing this business trend, you start to help a substantial environmental.Working remotely gives your workers the advantage of escaping the daily commute, which requires them to fuel their cars regularly. With the chance to allow your personnel to work at home or any place that would better suit their efficiency and productivity, you also help the environment by cutting down on fuel emissions.Even though you have many employees still working for you, you do not have to acquire a big space with your office. You can get a small office space which minimizes your consumption of water and electricity.
B. Saving The Environment By Being Paperless
That days are gone where you have got to print and collect all files acquired in your email or all of the reports you've got arranged for your immediate head. With the innovative characteristics of storing data within the cloud, you are doing not need large filing cabinets to gather your printed copies. By Green cloud computing companies and organizations can do with paperless.When you are connected on the net, you'll be able to see options like Google Drive, OneDrive, Dropbox, or SharePoint. These storage options gives you and your whole team to travel paperless. By using these cloud storage options offer drag and drop features for all of your documents, you'll still expect productivity within the entire group or organization even when working remotely. For emergence of Adobe Sign or DocuSign, there's no have to print any file for one signature. These technology innovations will gives you to download any files, fix your signature and send it back to whoever wants it without printing any pages and with just the employment of PC or laptop.The use of those green cloud computing tools makes it possible for organizations in several industries to cut back paper product consumption, if not eliminating it. This approach creates a big impact on the environment as you chop down the requirement to regularly purchase paper products, shred your documents, or eliminate your files.
C. Reduction of your Power Consumption to Decrease Energy Use
While the Reduction of your companies power consumption doesn’t only mean turning off your computer or your workstation lights when not in use. when your company runs on-location servers then though this can make a big difference, you have to know the information about gravity of consumed power. After Switching to the cloud wecan reduce your reliant on these on-premise servers. That is you also need lower machines in your office location, thus less space, and cooling requirements, leading to a reduced power consumption rate. Savings from these freed up capital expenditures can be gives to other environment-friendly projects or business development ventures like enhancing your marketing strategy campaigns.
VI. GREEN CLOUD COMPUTING APPROACHES
