Now, many companies seek to receive the greatest efficiency from the production. Therefore, the companies apply the cloud information systems www.bpmonline.com/crm/web-based-crm-software allowing the organizations to increase the speed of data exchange and information and also, to provide the decrease in time expenditure on the performance of identical operations.

By means of cloud information systems, it is possible to get access to dynamically scalable computing resources and applications through the Internet which is provided by the service provider.

Cloudy information systems have made changes to traditional approaches to management of applications and use of information at a remote distance. As with their help, it is possible to carry out interaction with various groups of remote users within one cloud, thereby developing large infrastructure. In too time cloud computing creates dependence on the service provider in data exchange with remote users, from the quality of service which reliability and stability of work in the network depends.

To ensure the coordinated work of the computer at which use of cloud computing is possible many uses the specialized software or middleware control by means of which monitoring of a condition of the hardware, balancing of loading is carried out, resources for the solution of a task are provided.

Service of cloud computing is an online application, access to which is carried out by means of the ordinary browser for work on the Internet.

Cloud computing in comparison with a traditional IT environment has the following advantages:

  • have a control system of storages of data, including multimedia storages;
  • allow to realize algorithms of automatic scaling of resources;
  • have control systems of virtual machines and network resources (IP addresses, domains), monitoring of resources and the general security system.
  • Inactivity of the organization’s cloud computing allows to create an economy of funds for contents and updating of the software, IT specialists, the electric power, service premises, and server disk space.

It is necessary to distinguish from shortcomings of a cloud computing:

  • the impossibility of trust to the service provider on the Internet of a trade secret of the organization, not only for storage of information but also for its processing;
  • inconvenience in the preservation of the intermediate stages of the performance of researches;
  • the existence of the risk of the use of information by the provider of an online service placed in a cloud.
