Cloud Computing Systems and Their Characteristic Features

If you are interested in cloud computing and the very meaning of these words, you can find many definitions on the web. All of them will in this or that way convey the main idea of this computing – a technology of distributed data procession, in which computer resources and facilities are rendered to users as an Internet service. The key words are “rendering services as an Internet service”, but it is possible to use not only Internet access to a server. A server can be reached through a usual local network with the help of some web technologies. Large web resources like Google and Amazon have become a ground for creation and development of cloud computing systems. Now, they are quite well-developed though rather new for website owners. They are provided by special cloud computing companies and are available for almost everyone.

Advantages of Cloud Computing

It allows their users save on purchasing effective but expensive computers. Also, employees can be more mobile because they can have access to their working place using a notebook, netbook or even a smartphone. There is no need to buy expensive licensed software, tune it and update. It is possible just to enter a service and use it paying for actual usage.

Clouds are very flexible because can provide unlimited resources like memory, processors, disks, etc.) due to their systems of virtualization, scaling and administration. Clouds are inexpensive for their users because using them involves less resources than a whole IT department of a company. Clouds are becoming more inexpensive with time because technologies used in them get more and more up-to-date, so their effectiveness grows. Finally, these clouds are reliable, because they have reserve power sources, security systems, professional technical support, provide regular backups of data they store and a great capability of their Internet channel. They can easily stand DDOS attacks. Clouds are a perfect solution for large companies that need to analyze a lot of data.

Several Minor Drawbacks

Clouds have drawbacks, but they are not numerous. For example, one of their drawbacks is a need of a stable internet connection for working with them. This problem can be solved easily with 3G and 4G technologies, but it is not always comfortable. Some experts also claim that clouds do not provide enough confidentiality. It is not recommended to save the most confidential and valuable documents at a cloud server, because its security is still questioned.
