Impacts of Cloud Computing July 11, 2017

The explosion of ICT is such that the deportation of computer processing traditionally localized on local servers is done on remote servers: this is called cloud computing. Our contributions are modeled in detail on a theory of improved breathability and thus created impact using established and related components to the environment Telecommunication (i), then the cloud stock (j) and the interactions between celles- those above and the (ij). Managers today must then create the virtual biotope to strengthen their control system because confronted with daily digital ecosystems. It would be important for regulators to have a serious staffing of control tools to deal with massive data so the term DATA BIG with its instruments becomes the rule to prevent cyber security. These works were presented at the first (CARET) African Conference on Regulation and the Economy of Telecommunications which took place from 26 to 28 October 2011 in Ouagadougou. in Burkina Faso by (ARCEP) and Telecom Paris Tech

Cloud computing: the advantages and disadvantages

Network Cloud

A great confusion surrounds the very concept of “cloud computing”. Several definitions and attempts at definitions exist today. For some, cloud computing refers to the totality of hosting services, while for others it is a question of providing a remote infrastructure. Some even define cloud computing as a ” federation of on-demand application services“. Interesting fact ; Although cloud computing is still a concept to be defined with precision, we are already talking about “cloud 2″, which is supposed to be the new generation (social and mobile) of the cloud.

In any case, one thing is certain; Cloud computing does not represent an offer as such, but rather an abstract notion. Or, as professionals like to conceive, a ” further dimension of outsourcing “.


Cloud computing is a concept that represents access to information and services, located on a remote server . To make it simpler, it is a form of outsourcing of the servers and related services of a given company.

Indeed, it is generally customary for a company to use its own infrastructure, intended for hosting its services. It therefore had to go through the traditional process of acquiring servers (becoming the property of the company), and that it take in charge the development and the maintenance of the systems essential to keep the servers running.

In this context, cloud computing is a solution that provides a remote architecture that is managed by a third party. The provider of this architecture therefore ensures the operation and the maintenance of the services which are accessible through a web browser.

In summary, it is a question of placing its data in the clouds, at a location unknown to the client concerned who will only care about the application part of this data, delegating the rest to its provider.

A concept. Several denominations.

The term Cloud Computing comes from the English language, but several equivalents exist in the language of Molière. Thus, professionals will evoke for example virtual computing, cloud computing / cloud computing, or even cloud computing.


Only you are able to answer this question, insofar as this solution answers a need that only the entrepreneur is able to determine the need.

This being said, in most cases, the implementation of cloud computing proves to be a wise decision . The concept allows to save loads which are generally quite considerable. Cloud computing is also one of the best forms of outsourcing of skills that are parallel to the trade. Since the supplier generally benefits from economies of scale, he is in a position to offer the same service for a particularly advantageous price. The supplier also has the means, in this case, to guarantee the development and maintenance of its service.

So, ultimately, cloud computing will maximize your efficiency and performance , increasing your productivity and reducing your costs.

It should not be forgotten that going through the provider of a cloud computing solution automatically involves questions of security and confidentiality of the data. To be monitored closely.

Back in detail, on the benefits and limitations of cloud computing.


Cloud computing is generally associated with a multitude of benefits that create unanimity among the company’s professionals. Note, however, that these advantages remain theoretical, given the very nature of the concept.

1. The ability to deploy and make major applications and work environments available immediately. The application updates are systematic, and the supplier releases its customer from any maintenance responsibility. An unbeatable simplicity therefore, which saves you in addition the expensive developments

2. Data can be shared, since any user of cloud computing can easily make his data available to one or more other CC users. It is therefore possible to create a virtual collaborative platform in record time.

3. A particularly powerful calculation, which is probably the shocking argument in favor of this type of solution. It is necessary to bear in mind that the structures limited to this level (computing power) can here afford a relocation of their processing, and thus benefit from all the resources and performances made available to them by the server of cloud computing. Although it concerns only a small number of companies, this advantage remains one of the most important of the CC.

4. Open and open access to the customer, who can establish a connection from anywhere and have access to his data immediately, without going through the installation of a virtual private network (VPN) in the company.

5. Constant monitoring of the development of your cloud computing space. You are usually informed in real time of the evolution of your cloud computing platform, since the installation of a software is not necessary and that access is made via a simple web browser

6. Total freedom, since you are not bound to your supplier by any long-term commitment. Cloud computing services are either billed on demand or by monthly subscription. You are therefore free to terminate this service at any time, if you do not need it, or if you simply wish to change the provider.

7. Cost: Because the same service is offered to many users, its cost is considerably reduced.


The controversial issue of privacy and security of your data remains the major limitation of this solution. The hosting of your data is done outside the company, in a basic service made available to you by your supplier. The risk of your data ending up in a theft or misuse situation thus remains a possibility.

Your role at this level is to ensure that your provider offers sufficiently comprehensive security and that it provides you with a privacy policy that encompasses all of your data.

Depending on the supplier chosen, your flexibility may be limited by the nature of the offer. For example, if you want to access certain features of your choice, your provider may be unable to offer them. Check with your supplier, therefore.

How to reduce the effects of cloud computing on the environment?

If the ecological impact of cloud computing is to be reduced, it is not a question of a few people or a small group of people, it is certainly the business of all.Because the increase in global energy consumption concerns all landowners. The fact is that the number of data centers is growing more and more because there is constantly additional data to be backed up. However, many are still storing in their electronic box mails of friends received for 8 years and which will no longer serve them anything. Many parents buy an iPad for each of their children, whose iPads will barely exploit 30% of their capacity. They not only increase energy costs but also the space occupied on cloud computing. In the enterprises,

At this level, the first effort to be made concerns each user. Clearing files that no longer serve any purpose on online storage (including e-mail) could already alleviate the problem of the need to increase the number of data centers. For large IT firms, adopting ecological behavior would obviously reduce the ecological impact of data centers, but would also improve their image and could reduce the costs they invest in energy needs. A possible solution would be to adopt a method of adiabatic cooling , much less energy-consuming and that does not let heat escape.

There are also very original ideas, especially the one that proposes to putcomputers in a radiator to limit the losses of heat, thus the waste of energy; In this case of course it would have to be adapted to the servers in the data centers.Another idea begins to impose itself and is evoked under the name of ecological informatics.

The cloud and the harmful data centers?

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.

Why games have their place in cloud computing

Video games represent a phenomenal market today, which is tilting each year more towards mobile platforms. The cloud is an increasingly essential tool for both players and developers, who need to stay competitive.

The rise of video games

As announced by Newzoo, a company specializing in the analytical processing of games: “Players worldwide will generate a total of $ 99.6 billion in revenues in 2016, an increase of 8.5% from 2015 For the first time, mobile games will account for a larger share than PC games, with $ 36.9 billion, up 21.3% globally . ” [1] Hideki Hayakawa, CEO of the video game publisher Konami, is not alone in believing that the future of video games is going through mobile platforms [2] . You may not have noticed the number of people in public places who have their eyes glued to their mobile screen playing Pokemon Go.

Mobile games have never been as rich as they are today in terms of content or visual stimulation. However, the good news for mobile gamers is that the processing power required to run a modern and ultra-powerful video game will probably not be accommodated in the compact format of the mobile device itself. Instead, the images are generated and powered by a back-end server in the cloud, which allows to bypass many of the limitations of mobile devices, in favor of battery life.

The importance of connectivity and data

Similarly, modern video games on ultra-fast consoles and PCs are increasingly connected, enriching the gaming experience while players communicate while playing in the same universe. Frank Gibeau, president of Electronic Arts’ EA Games division, confirms: “Given the way our products evolve, I am convinced that they need to be connected online. Multiplayer is just [ 3] . “

The future of video games, therefore, revolves around greater connectivity between players and between the software and the game server. This can include streaming videos on low-powered mobile devices or letting the generation Images to more powerful desktops or systems, while running the game in the background.

There may be a number of reasons for this. Not only do many games (whether hosted in the cloud or not) require low latency, but transactions are often data-intensive, so the gaming experience is extremely sensitive to the quality of the network connection. Deploying game servers to an international cloud infrastructure brings players closer to each other, helping to reduce latency.

For the future, virtual reality creates a totally immersive gaming experience, whether on the move or coupled with a powerful desktop system. Now, in conjunction with augmented reality, virtual reality is a major trend in the video game universe, even though it is still in its infancy. Many consumers do not yet know what virtual reality brings them, nor is it worth the expense [4] .

If and when virtual reality grows, however, it will require even more data and the cloud will have to provide the infrastructure required to produce high volumes of data at low latencies.

Cloud computing solutions

Cloud computing services are not just about gaming: companies can also take advantage of data in the cloud to quickly make business decisions. The Halo franchise used a Spark and Hadoop service to process and analyze the raw data based on cloud computing in order to feed the tournament organizer’s game statistics, which then exploited the Data to rank players based on their game performance. These data allowed Halo 4 to be updated weekly and feed a campaign to send daily mails to increase player retention.

Thus, for many, if not all, games, the cloud provides an essential infrastructure layer that enables game development studios to provide a richer, more reliable gaming experience. The era when players themselves had to provide their own physical server for other players will soon be over and replaced by cloud-based servers, whether purchased by video game publishers or players.

The cloud not only allows gaming to have a more global reach, while improving the gaming experience, but it also eliminates the burden of buying and managing the infrastructure, enabling developers to focus on What they do best: create a stimulating and immersive entertainment.

Cloud: adoption is there, maturity safe yet

Today, the cloud is a must in many companies. Applications in Saas, dedicated cloud or public infrastructure: the solutions are numerous and are declined according to the use cases, but the question of the confidence and security of the cloud remains at the heart of the debates.

This is the topic chosen by Cesin, the Computer Security and Digital Experts Club, which publishes a survey based on a survey of 91 of its members on cloud security practices . 91, it does not matter, but Cesin members have many RSSIs from major French organizations, which gives a partial but significant insight into cloud security practices in French companies.

The first observation of the study is that of the mass adoption of the cloud with the respondents: 90% of the respondents explain thus store to process data on a cloud. The use of this one remains a minority in front of the applications on premise, which remain majority, but the use of the cloud is widespread.

However, on the other hand, security still remains another pair: 47% of respondents explain that they did not integrate the cloud dimension into their information security policy at all, and only 25% developed a specific policy entirely Dedicated to the use of the cloud in company.

The other aspect that emerges from this study is the dependence of businesses on large cloud infrastructure providers. For example, many respondents (69%) were concerned about the rapid evolution of cloud solutions, whether from application compatibility, security settings or, to a lesser extent, auditing capabilities.

Apart from those who do not manage to follow the pace imposed by third-party actors, respondents would like facilities to recover logs, audit systems or even contract.

58% of the respondents explained that the major SaaS providers offer contracts that can not be changed, forcing companies to adapt their security policies to the terms imposed by service providers. A not insignificant advantage: that of continuity of activity. Surveys favor this aspect, as well as that of cost, which remains to the respondents the main assets on cloud.

Can cloudless IT policies survive?

There was a time when IT computing departments were managing the technology for the company as a whole and the business units had to pass on all of their IT needs to the IT department.

Then came the shadow IT, in other words the deployment of applications based on cloud computing at the level of departments and business departments. Studies show that this phenomenon was and still is motivated by operational unit managers who simply want the work done quickly, while official channels are too slow. In other words, the adoption of cloud services has enabled the company to become more agile.

What impact has the emergence of this “cloud computing” on the position of the companies vis-à-vis cloud computing, and in particular those having implemented a policy without a cloud?


The shadow IT is here to last


The problem of shadow IT, if it is actually a problem, is not about to disappear. Both the scope and the number of cloud computing services are expanding, offering an increasingly attractive, even for the most opposed to the cloud.

CIOs must therefore manage the access to the cloud of the shadow IT, from a technological as well as a psychological point of view, because the enforcement of rigid rules is unlikely to succeed. On the contrary, policies favoring cloud computing, or even giving it exclusivity, will become the norm in the company, according to Gartner’s studies. As a result, cloud-based technologies and techniques that help people who need quick and easy access to cloud services will also grow.

This is not to support the idea that access to cloud services should be allowed without appropriate controls, but rather to recognize that the pressure to adopt cloud services tactically will only increase and To ensure that mechanisms are in place to promote it while minimizing risk.


Key role of the MSP


Access to cloud services must be quick and easy within a policy framework, for example. For example, a Managed Services Provider (also referred to as an outsourcer) that relies on a large cloud provider for its offerings must be able to activate a service quickly, assuming that it understands the security and other policies of the organization, S business.

The risks associated with unauthorized access to cloud computing services should not be overlooked. Access regulation will be particularly important for companies in many sectors, while other issues such as software resource management and software standards may be in conflict with compliance requirements, regardless of sector. ‘activity. However, for example, security policies need to distinguish, from a security risk perspective, between the last marketing presentation and a spreadsheet from the finance department.

Most companies are likely to welcome assistance in managing such risks. As a result, outsourcing becomes a pathway to cloud computing services, but also a crucial part of the IT process, helping to activate cloud services for business unit managers and using its experience to manage shadow IT At least access to cloud services).


The “cloudless” destined to disappear


So the quick and easy answer to the question of policies without a cloud is no, these policies can not survive. Market research confirms this: Gartner believes that by 2020, a corporate policy spreading cloud computing will be as rare as a policy without the Internet today.

Jeffrey Mann, Vice President of Research at Gartner, said, “We believe this position will become increasingly untenable.” Cloud computing will gradually emerge as the default option for software deployment. The same goes for custom software, which is increasingly designed for a variant of the public or private cloud. “[1]

Meeting internal demand for the ever-broadening range of cloud services is the only way to ensure that business units do not jeopardize company data and do not -conformity. This request will not disappear; It is the cloudless policies that need to be eliminated.
