Cloud technology - a convenient medium for storing and processing information, which combines hardware, licensed software, communication channels, as well as technical support to users. Working in the "cloud" is aimed at reducing costs and improving the efficiency of enterprises.
A feature of cloud computing is not attached to the hardware platform and geographical area, and the possibility of scalability. The client can work with cloud services from anywhere in the world and from any device with Internet access, as well as to respond quickly to changing enterprise business objectives and needs of the market.
In addition, this approach allows us to standardize the software on computers even if the companies have different operating systems (Windows, Linux, MacOS, etc.).Cloud technologies facilitate access to company data for both customers and for its own employees who are out of the office, but having the ability to connect via the Internet.
Private Cloud (English private cloud.) - Infrastructure intended for use by a single organization consisting of several users (for example, units of one organization), it is also possible clients and contractors of the organization.
Model deployment of cloud technologies
Public cloud (English public cloud.) - The infrastructure for free use by the public. Public cloud may be in the ownership, management and operation of commercial, academic and government organizations (or any combination thereof).
Model deployment of cloud technologies
Hybrid cloud (English hybrid cloud.) - A combination of two or more different cloud infrastructures (private, public or public) that remain unique entities but interrelated standardized or private data transmission technologies and applications (eg, short-term use of public cloud resources for load balancing between clouds).
Cloud - it's not just virtualization.
Although server virtualization and infrastructure is an important foundation for private cloud computing, by themselves, virtualization and management of virtualized environments are not yet a private cloud.
Virtualization allows you to better structure, pooled and dynamically to provide infrastructure resources: servers, desktops, storage capacity, network equipment, middleware, etc.
The main properties of cloud computing
The National Institute of Standards and Technologies NIST (National Institute of Standards and Technology, USA) in his paper.
"The NIST Definition of Cloud Computing" [5] defines the following characteristics of clouds:
Availability of Broad Network Access System;
Concentration of resources in certain areas for their effective distribution;
The possibility of a high degree of automated self-service by the provider system;
rapid scalability (unlimited resources can be allocated and released at a high speed depending on the needs);
managed service (cloud control system automatically controls and optimizes the allocation of resources).
Cloud computing (English cloud computing.) - Information technology concept, which implies providing universal and convenient network access on demand to a common pool (Eng pool.) Of configurable computing resources (eg, data networks, servers, storage devices, applications and services - both together and separately) that can be provided quickly and released with minimal operating costs or calls to the provider [1].
The smaller the time, cost and complexity of adding or extending the functionality.
