The Developed countries are increasingly subject to called technology of cloud computing. This technology gradually begins to penetrate into the business structure.
What is cloud computing
It is a model of universal and convenient network access that can be produced quickly and released with minimal effort management and the need to communicate with your ISP.
In order to better understand what is cloud computing? I can give you a simple example: before the user to access the emails resorted to a particular software (messengers and programs) installed on his PC, but now he simply visits the site of the company whose services e-mail to him like, directly from the browser, without the use of intermediaries.
Here Are Three Models of "Clouds"
SaaS, Software as a Service. The customer provided the software - an application service provider running on a cloud infrastructure.
PaaS, Platform as a Service. The consumer is prepared for deployment to the cloud created by the customer or purchased applications developed using a supported provider of tools and programming languages.
IaaS, Infrastructure as Service A. Consumers are provided with the means of data processing, networking and other basic computing resources.
The benefits of cloud services
Last year, the total volume of the world market in the area of cloud computing was about $ 40 billion. Some experts predict that by 2020, this figure will reach $ 240 billion. There are several advantages associated with the use of cloud technologies.
Availability. Access to the information stored on the cloud storage, it can get everyone who has a mobile device or tablet and computer, connected to the Internet. This implies the following advantage.
Mobility. The user has no permanent attachment to one workplace. Managers can receive statements and monitor the production.
Cost effective. One of the important benefits is called reduced costly. The user does not need to buy expensive, high computing power of computers and software, and it is exempt from having to hire a professional to service the local IT-technologies.
Lease Amount. The user receives the required service package when he needed it and pays really only for an amount of purchased functions.
Flexibility. All the necessary resources are provided ISP automatically.
High technology. More processing power, which is provided to the user, can be used for storage, analysis, and data processing.
Reliability. Some experts argue that the reliability of which provide modern cloud computing, arguing that few companies can afford to buy and maintain a full-fledged data center.
Google Apps for Business allocates the same benefits, but adds that by using their cloud computing company protects the environment, explaining that the service Apps work on the basis of data centers Google, other than ultra-low power consumption, and therefore carbon intensity of energy consumption in their use will significantly lower with local servers.
How much all these cost?
The cost of Google Apps for Business, according to the company, $ 5 per user per month, with free space for cloud disk 5 GB (you can buy another from 20 GB to 16 TB for as low as $ 4 to $ 1430 per month, respectively).
The user can also purchase Google Apps with a safe for $ 10 a month, which includes a standard package plus archiving of important business data, the data collection for the needs of the judicial, search and export of all corporate data. It should be noted that the user is considered one email.
Microsoft is also fighting for its share in the field of cloud computing. Their foundation is Office 365. It focuses on comprehensive CRM-solution, arguing that Microsoft Dynamics CRM includes control units marketing, sales, and customer service. That is, with this function it is possible to solve the range of problems relationship management, starting with the involvement of clients and cross-selling. It stands out as a "smart" analysis, role-playing interface, and high mobility.
Despite all the positive reviews, there are some disadvantages of cloud technologies.
Experts point to the problem of uncontrolled data: information of the user will be stored without his knowledge or he will not be able to change some part of it. On Google properties the user will not be able to remove unused services to them, and even individual groups of data.
