From the beginning of cloud Computing rapid development, most IT-specialists in details have described different sides of merits and demerits of this technology, that way, having forming camps “pros” and “cons”. Nevertheless, today, cloud technologies are one the most fast moving destinations in the world.
The term “cloud” is in use like metaphor to represent the internet on the map of the network. Cloud is a set of interconnected equipment (computers, servers and data storage devices).
Cloud computing – is a technology of data processing, where computer resources and capacities are given to user in the form of Web service.
For effective work and development of clouds needs powerful information technology (IT), such as broadband links, high-end servers, trusted and secure means of data protection.
Today cloud`s dependence of the Internet is very similar to the dependence of electricity. Because, in modern society to find the person who doesn`t use PC (or other gadget) without accessing to the Internet is rather difficult, and moreover, no one business office couldn`t completely work having no access to the Wide Area Network.
For cloud`s work it is necessary constant high-speed connection with Internet. It is because of many “cloud” programs requires good Internet connection with a big channel capacity. Broadband link (also high speed) allows work with the Internet 40 times quicker than Dial-Up (with using modem, which is plugging in analog subscriber line of telephone network of common use) and DSL (digital subscriber line). It should be noted that, with developing of communication, the cost of telecommunication services over the last decade significantly decreased, but channel capacity and productivity of existing communication channels has increased, which played not a significant role in the spreading of cloud computing.
Programs, which are situated in the “cloud” could work slower than in the local computer and be independent of rate limiting link channel. The whys of it can also be a problem in the path between the user and the "cloud”. To avoid the problems with the server from the technical side, it is necessary thoroughly choose the provider.
Sure, with time already rich feature of "cloud" software will expand, but today the "cloud" lose their boxed counterparts predecessors. For example, documents, tables and presentations in the Google Docs in the comparison with similar office applications as Microsoft Office by it`s functionality loses last. In cases when required functions in the "cloud" service are available, it is efficient to use packaged software and optionally send to "cloud" the files themselves.
Cloud computing are in daily use of an impressive number of Internet users already, giving at the very least possibility to get access to own data, which are situated in the “cloud” at any point of the Earth's surface, where there is the ability of internet connection from any device of the new generation.
