The arising scenarios in the coming years will be totally different from the current we know. The technological advances will cause renewal of many aspects of our daily life. However, the high level of energy consumption of the twentieth century also obliges the technology which improves every aspect involving the production processes. One of the paths is the Green Computing.
The Green Cloud Computing corresponds to the strategies and the development of computer systems that look to utilize resources efficiently in order to decrease the impact of IT processes on the environment. Cloud computing is based on technologies that contribute to the achievement of these strategies.
One of the important keys to understand the reasons why cloud computing improves productivity and reduces the energy impact is the phrase ‘Less is More’. By using the cloud, companies are able to stop the use of internal servers and can take benefits of softwares that runs off their company systems. This way it help companies to minimize the investments on equipments and reduce energy consumption.
Apparently, it does make sense that to offer services like cloud storage and other cloud-based services, companies need to leverage its size to optimize the memory space and execution. This is a traditional way of outsourcing, but is mostly applied to computer processes.
The main obstacle and challenge in order to achieve a real ecological cloud and for companies providing cloud computing services, is to build efficient data centers, so that the energy consumption and environmental impact is reduced. In the cloud industry, this is one of the great careers.
Today, many companies and individuals considers the cloud computing as a best way to increase energy efficiency and helps to create a more sustainable environment. However, people are still not aware on how to choose a cloud computing service provider contributing to a sustainable environment. However, many people proceeds to the green image of cloud computing as a main reason to drive adoption. Definitely it is a kind of service which is more effectual than that of the traditional servers which are deployed locally.
Do you think that cloud computing is really green?
Cloud computing is more than other systems. No doubt, that cloud computing achieves greater efficiency which leads to a more sophisticated environmental protection. However, there are some commonly assumptions that I believe are not totally accurate.
One of the statements that are accepted without reflection is the reduction of energy consumption will reduce the carbon emissions. In reality, there is a direct relationship between these two variables. It is clear from the below example:
“If a service is migrated to a cloud provider that acquire its energy from coal is likely going to release more carbon dioxide into the atmosphere than a provider whose resources come through a nuclear plant.”
To cater an overall scenario of the market, it can be said that the United States holds a big part of cloud providers. The country has a one of the largest power grids that emit more carbon dioxide.
Well, the countries like Europe, UK and France are also among those countries hosting more companies for cloud services. Especially, in case of France, the utilization of energy from nuclear plant is very large, which generates one of the grids that release less carbon dioxide in the atmosphere.
This cannot be concluded to all companies individually, but it does gives an idea of how a United States based cloud provider could produce more carbon emissions than a local server in France.
The trick is that the “green character” of the cloud not only depends on the amount of CO2 released into the atmosphere, but also of its removal processes.
