Abstract

The article deals with «Cloud computing» (Cloud computing) as an alternative to the classical model of education, benefits The use of a lachnyh computing in education. Describes in detail the most important of them are: economic benefits, flexible scalability, you are a sokaya availability, reducing the impact on the environment, satisfying to the needs of end users, focusing on the key task chah, data security, etc.

Keywords: cloud computing, cloud-based applications., computing resources, educational institutions, IT-infrastructure, model training, software, system, TV communications equipment

Currently, without the use of modern information tech-technologies can not work effectively no educational institution. The content and the development of its own IT-infrastructure at each educational center is very expensive. Every year the level of data costs more and more increasing. Institutions spend big amounts on computers, telecommunications equipment and pro- SOFTWARE. In addition to these significant financial costvye investment required and to maintain a high level of professionalism these employees.

“Cloud computing» (Cloud computing) - is a good alternative class classical model of education. Its main advantage can be regarded as a significant environmental any savings means the educational institution in which they are used. Indeed, in the this case, the computer infrastructure and / or information services pre- delivered as a service “cloud” provider. Documents, pisma, programs and other data involved in the educational process are stored on remote servers provider. Thus there is no need for the establishment of contain their own expensive IT-infrastructure and overpay for numerals resources which in most cases are not used to the full power. The only thing that is necessary to ensure that teachers and obuchayuschih-Xia using cloud technologies, - access to the Internet.

Currently, there are many providers of cloud solutions. Large companies such as Amazon, Google, Microsoft, and so on. D. Offer significant discounts to educational institutions, due to what they get access to cloud services at virtually no cost. The use of cloud computing in the field of education has many positive aspects. Particularly important among them are the following pre-property:

* Economic benefits. Using cloud technology is not require capital expenditures for the creation and maintenance of their own centers data processing purchase of server and network equipment to create own IT-infrastructure. Does not require the purchase and installation of pre-rogostoyaschego software platforms and regular updates systems. All of these costs are borne by the supplier of cloud solutions. resulting in reduces the load on the technical staff, allowing use of the same researchers in other, more useful for the establishment of projects.

* Flexible scalability (elasticity). Due to such characteristic cloud services, as elasticity, at the educational institution has to gradually increase the volume of services used without significant prior investment. In peak periods (for example, in the sessions) do not need to plan the introduction of additional informational capacity as cloud services can be scaled autocally and practically unlimited.

* High availability. Cloud services are available for 99.5% of the time to time, and some providers guarantees the availability at the level of 99.9%. Is This very convenient for teachers and students, as they can impleseized the opportunity to train at almost any time and do not depend on the local information and educational resources agencies. resulting in - this results in a tremendous time savings. In addition, the constant pre affordability of removes the barriers to obtain distance education, for measures in remote areas, where the learning process may influence the difference in time. High availability of educational resources has a positive effect the ranking of the educational institution.

* Reducing the impact on the environment. In accordance with the “green “concept of data centers should use energy- saving technologies in design and operation. As practice shows teak, to reduce the impact on the environment is advantageous to use cloud services that use “green” technologies, than to introduce such technology in the local IT-infrastructure.

* Meeting the needs of end users. for end .Users cloud technologies provide even more benefits.

Very handy when data is available from any place where there is Internet access and any device, be it a PC, smartphone or tablet. Users do not need to worry about backups, data storage is safe are stored by the “cloud”. Cloud infrastructure ensures data. If we talk about the standard office suite that comes educational institutions for free and can be used to address a very wide circles tasks, the students do not need to purchase, install and updateit on their computers. The only app that will require update - a web browser.

* Focus on key tasks. In any field of education the main task educational institutions - a strong focus on education and issledovanis. When using cloud technology reduces the cost of deployment and support used in the application, released human resources that may be involved in the learning process. Cloud technologies are relatively new, so some it seems to distrust him. Not every IT leader .Units agree to give part of service outsourcing and / or place key data necessary for the functioning of the organization, as well as confidential information from third parties. Consider the main risks associated with the use of cloud technologies.

* Data security. The main risk is considered to be data security. Many companies and organizations find that their data are more security, if they are stored in the local information environment where physicalcally possible to see the data carriers or equipment that neposreds- tively involved in processing data. Some managers even difficult imagine a situation that the data being dealt with in the present time can be physically located in the data center, located on the other continents and in other countries. In fact, the specific reasons for fear not. Data during transmission over open channels are encrypted data, further this when the contract is signed with the provider agreement non-disclosure of confidential data. The main risk for providers is the fact that a violation of privacy or loss of data even one user (student or employee of an educational institution) the user can sue the provider of cloud services, which may lead to huge costs and greatly damage the reputation. Therefore that in today's competitive market, each of suppliers cloud technology tries to make every effort to ensure Berity and data integrity.

* Reduced availability. As mentioned above, many suppliers cloudiness services guarantees the availability of its services for 99.5% of the time. But, unfortunately, we can not forget about the existence of, for example, hacker attacks such as “denial of service» (DoS-attack), which can reduce the total time availability. To further minimize risks should be used services of several Internet service providers.

* Link to the supplier. Another serious risk is binding to specific cloud providers. Since the cost of migration Local significant cloud environment, in the case where the supplier stops meet the needs of an educational institution for any criteria ria (increase the fee for use, the market will be better and cheapest service, and so on. d.), change it to be quite problematic. Cash and time costs can be enormous. It is therefore necessary respontively to the choice of cloud providers. Development of cloud services in education can not continue without determined institutional and legal changes. Organizations that plan to deploy cloud technologies, first all, you need to review the policy with regard to safety and con-privacy of data. All risks of loss and disclosure of confidential data should be regulated by direct agreements with providers.

It is recommended to consult with lawyers and make appropriate due changes in the service agreement. Staff, previously involved in the operation of IT-infrastructure organizations, should be redirected to the installation, configuration and control oblachnyh services. System administrators will have to accept the fact that . End users no longer follow the internal regulations on the use of information and technical resources, as origin goes with the traditional organization of work without the use of cloud calculations.

With regard to intellectual property rights to the data obrabatyva- employed in the cloud, you need to very clearly specify them in the contract. In agreement Governing the provision of cloud services should be pointed out that the right of property bility to the data placed in the cloud and started must remain in user. If all the educational materials will be placed in the “cloud” educational organization, you are likely to need other registration intellectual property rights. In European countries, separate educational institutions (schools, colleges, universities) to discuss the terms of cloud services at the level of national and regional education authorities.

Additional advantages here is that several education successive institutions can become part of a “cloud” that facilitate co-operation and accelerate the exchange of experience between such institutions. As practice shows, the first cloud technology develops fine and medium-sized businesses, as well as a variety of start-up projects. educational institutions Denia due to the specifics of their internal processes will be able to transfer your License keys chevye services in the “cloud” is not soon. It is one thing - it's to outsource such services as e-mail, and quite another - to translate into the “cloud” sophisticated learning management system (LMS). computing education information

We live in an age of information technology, which change very dynamically. Cloud computing providers each year to improve pre- the services offered and expand their list. In the free cloud products from Microsoft and Google are already functions that have some training in LMS institutions. This will facilitate the gradual migration of educational institutions in the “cloud”.

In addition to free cloud-based applications, there are specialized Rowan LMS, as Blackboard, Moodle and Desire2Learn, which can now expand freely in the “cloud.” Therefore, it seems doubtful that future educational organizations will want to establish and maintain self-LMS pendently on their internal resources, if cloud providers can provide access to safe, readily available and cheaper counterparts traditional LMS.

A major role in the transition to cloud technologies will play the final Polish ducer. Along with the widespread increase in speed Internet access to information in the “cloud” will become faster, easier and more convenient. Web applications will be improved, personal data can be fearlessly stored in the “cloud” rather than on their own devices, which can in most inopportune moment fail. Thus, some requests to use the use of cloud technology will come not only from the educational organizations, but also by the end user.
