The Internet became an integral part of life of people, and the new opportunities capable to facilitate performance of different tasks regularly appear. A novelty are a cloud computing which can be applied in different spheres: education, medicine, logistics and so on.
What is a cloud computing?
Let's begin with definition, so a cloud computing means a possibility of the user to have access to data, without installing applications on the device as all providing is provided by servers. It is important to know that such services can be both free, and paid, and everything depends on inquiries. To understand what application of a cloud computing consists in, it is necessary to sort their difference from usual conditions.
- For an example we will take e-mail when the e-mail client is established on the computer and all data remain on the hard drive. In this case the user himself decides what to do with files.
- If to speak about mail which the person uses via the browser then it is already cloud technology. Here it is clear that if there are problems with the server, then access to mail will be lost.
Advantages of cloud services
For a start we will stop on the existing pluses to which carry:
- For storage of information it is not necessary to buy expensive computers and components, everything will be stored on "cloud".
- Personal computer performance increases, a cloud computing in office-work and other spheres remotely starts programs therefore on the computer there is a lot of free space.
- Every year problems with service decrease, the number of physical servers constantly decreases, and the software is constantly updated.
- Costs of purchase of the software as it is necessary to buy only once the program for "cloud" and everything decrease, and sometimes it is possible even to order its rent.
- Cloud computing has no restrictions in volume of the stored data. In most cases volumes of such services are estimated in millions of gigabytes.
- Programs are updated automatically therefore to watch it there is no need, as in a case with downloaded applications.
- "Cloud" can be used on any operating system as access to programs is provided via web browsers.
- New cloud computing gives the chance always and in any place to have access to documents, the main thing – existence of the Internet.
- Good safety and protection against loss of information as the put in order data automatically remain and chip in together copies for spare servers.
Shortcomings of a cloud computing
Has "cloud" and a number of minuses which should be known and considered:
- Access is impossible in the absence of the Internet and if it is absent, then it will be possible to work only with the documents loaded on the computer. It is worth noticing that the Internet has to be fast and qualitative.
- The cloud service can slowly work by transfer of large volume of information, than in case of the installed program.
- Seldom safety is at the bad level, but in most cases "Cloud" makes backup copies therefore it is not necessary to worry.
- Confuses many that it is necessary to pay for granting a number of services, but it is the business project from which people have to earn.
Application of a cloud computing
There is a certain classification of cloud services, so mark out such categories of "clouds":
- Public. It is IT infrastructure which can be used by a large number of the companies and services at once. Any company and the certain person can be the subscriber. Users of a public cloud computing have no opportunity to operate and serve "cloud" as only the owner of service is engaged in it.
- Private. Describing types of a cloud computing, it is necessary to stop on this safe IT infrastructure controlled and operated for the benefit of only one organization. It can be placed in rooms of the customer or at the external operator.
- Hybrid. This look has main advantages of both previous options. Such "cloud" is in most cases used by the organizations which have the seasonal periods of activity that is when there is not enough internal IT infrastructure, a part of capacities passes to a cloud computing.
Cloud computing in education
Computers and the Internet made the way also in an education system thanks to what it is possible to improve and facilitate process of performance of a number of tasks. A cloud computing in educational process can be used for such purposes:
- The organization of collaboration of employees over important documents, for example, the annual plan or the program. Everyone is responsible for the part of the document, and still if necessary at all users an opportunity will leave comments and to supplement information.
- The general project work, so the teacher can transfer to pupils of a task, divide duties and check reports, giving comments.
- Cloud computing can be used for creation of the electronic diary and transfer of any written tasks. It is a great option for children who undergo house training or in any reasons skip classes.
Cloud computing in medicine
Recently "cloud" actively takes root into medicine that lifts it to new level. New technologies give the huge potential for revolutionary changes, it becomes much simpler to conduct and systematize medical documentation. Application of a cloud computing in medicine is important as they help to define quicker the diagnosis and to make the conclusion. At the moment such service only begins to take root as so far there are no regulatory mechanisms of preservation of medical secrecy.
Cloud computing in logistics
Excellent potential has "cloud" in transport and warehouse logistics. By means of a cloud computing it is possible to provide full interaction of all participants of a chain, that is the sender, operators, transport company and the recipient. All of them can conduct communication in real time irrespective of the location. Use of a cloud computing gives such advantages:
- to hold open tenders for contractors;
- to define the most successful routes;
- to control delivery;
- to carry out processing and to store all data on transportation;
- to increase quality of implementation of the order.
Cloud computing in banking sector
The competition among banks is huge and not all are capable to stand at the time of crisis. Such financial organizations begin to apply innovative technologies to cut down costs. Cloud services of data storage are directed to automation of financial processes. Increase in overall performance of credit institutions due to cut in expenditure on drawing up the reporting results. It is important to note that as there is a threat of penetration of malefactors into cloud storages, do not store the information about clients in them.
Cloud computing for business
The people who are engaged in business use "cloud" for such purposes:
- Rent of the virtual server is made thanks to what the head can control completely all placed services irrespective of provider.
- In network it is easy to create virtual contact center thanks to what it is possible to save on rent the room and the organization of jobs. Work can begin in two days from the moment of application to provider.
- Cloud services for business are used for creation of virtual office, that is the workplace will not be tied to the concrete computer. In "cloud" the internal network of the company is reproduced, that is disks, folders and programs for planning enter.
Games through a cloud service
In the 2000th years, services of a cloudy streaming began to appear thanks to what users can play online "heavy" games, without carrying out downloading and without loading the computer. In America and China this direction already has good development. Recently Microsoft made the official statement that the DeLorean system thanks to which the person will play through a cloud service will be developed, and the system will foresee its actions before he presses keys.
