The cloud and the harmful data centers? July 11, 2017

The Cloud, what is it?

Cloud-computing-1The cloud is derived from cloud computing, still often referred to as cloud computing, which designates a set of technologies allowing the realization of professional or personal computer operations remotely. In other words, cloud services allow you to take advantage of the performance of hardware infrastructures, operating systems or software that you do not own yourself. Hence the three forms of cloud services that exist: IaaS (Infrastructure as a service), PaaS(Platform as a service) and SaaS (Software as a service). How it is possible ?Simply via the Internet, and Cloud technology!

Through Cloud’s definition, there are already many positive points. And the advantages of the cloud are indeed numerous: remote storage, e-mail, etc. All thanks to datas centers in France or elsewhere. A data center is a center of servers on which are stored, and through which pass all data from cloud solutions.But all this involves enormous energy expenditure.

The ecological impacts of data centers

Data CentersThe consumption of a data center in terms of energy is expressed in thousands of kWh (kilowatt hour). The explanation is quite simple when one understands the principle of operation of this set of techniques. Servers or super-servers, which are the path of transition and data storage, must necessarily remain functional full-time. It would still be a shame if we had to wait for a specific time before we could send a mail, all the more with the jet lag … it would be catastrophic. Then the machines must be switched on at all hours, and therefore must be constantly supplied with electricity. And this only refers to energy expenditure in a data center only.

The next step is to think a few seconds about the amount of data each Internet user uses per day online using cloud computing services … or simply the amount of responses Google search each search operation. It’s a huge mass of data that’s at stake. Then you have to imagine the thousands, millions, and then the billions of web surfers that are connected every day. The numbers are stunning. For the small idea, Google searches each month involve 3,900,000 kWh, or even 260,000 kilograms (kg) of CO2. This corresponds to the amount of energy that would keep a 100 watt incandescent lamp lit for 4.534 years, just that. Not surprisingly, the statistics on world energy consumption are increasing dramatically. Then you have to consider the electricity consumed by the huge cooling systems in place to prevent overheating of the servers. While with a small maintenance of data center, an adiabatic cooling system put in place consumed for example much less. Eh yes ! It’s easy to settle for Cloud, to focus on the benefits of the cloud, not thinking about its ecological impacts and how to reduce them, without asking how to reduce its ecological footprint. Then you have to consider the electricity consumed by the huge cooling systems in place to prevent overheating of the servers. While with a small maintenance of data center, an adiabatic coolingsystem put in place consumed for example much less. Eh yes ! It’s easy to settle for Cloud, to focus on the benefits of the cloud, not thinking about its ecological impacts and how to reduce them, without asking how to reduce its ecological footprint. Then you have to consider the electricity consumed by the huge cooling systems in place to prevent overheating of the servers. While with a small maintenance of data center, an adiabatic cooling system put in place consumed for example much less. Eh yes ! It’s easy to settle for Cloud, to focus on the benefits of the cloud, not thinking about its ecological impacts and how to reduce them, without asking how to reduce its ecological footprint.

It is necessary to note that all the consumption of a data center, added to datas centers in France and in the world, is partially converted into heat. This heat, unused, inevitably ends up in the atmosphere or in the oceans, and thus contributes to global warming.
