The cloud that comes ...

For some time there has been talk of cloud computing. Taking as a starting point to Wikipedia is defined as:

Cloud computing (cloud computing), is a technology that can offer computing services over the Internet. In this kind of computing can offer everything that a computer system is provided as a service so that users can access the services available "in the Internet cloud" without knowledge (or at least without being experts) in the management of the resources they use.

From the very definition of cloud computing may draw some important conclusions on the use of such systems such as:

1. Reduced costs: Any company can have the computing elements to meet your needs at a cost lower than required when installing own dedicated servers.
2. System scalability: The enlargement or reduction in the capacity of the enterprise computing can be achieved in a simple and fast, being able to create dynamic computation structures for carrying out specific processes at key moments. With this scalability avoids expensive licenses for long periods of time (only pays when used).
3. Potentiation and creation of new markets: Obviously start new start-ups appear exclusively dedicated to the creation of cloud services to both businesses and individuals, thus creating new market opportunities.

As in any system, not all benefits. Cloud computing from my point of view presents a major drawback, Security. The fact that your online information is not controlled servers put on trial some aspects regarding information confidentiality and security of stored data.

For example of what may be the cloud computing, then show some services on the network:

Zoho : Suite of tools for personal production / business online. Zoho allows you to create text documents, spreadsheets, presentations, mail manager, CRM system, online repository and one or more functionality. They provide plugins to integrate zoho in Microsoft Office and integration into mobile devices.

Amazon Web Services : Truly impressive is the system that Amazon has set. Amazon Web Services is a fully configurable system where you can have online virtual servers with different operating systems, storage systems, databases, etc ... The funny thing about Amazon is the system of charging. For example, the servers are billed per hour of use. Furthermore, storage systems only billed at the time you upload or download information from the system (internal transfers between virtual servers and storage systems and databases are not billed).

EyeOS : It is a fully operating system online. This draft is currently Spanish origin, from my point of view, an online operating system more stable and more features. The Online Operating System includes an office suite, email manager, FTP manager, video and audio players, viewer / generator pdfs. All this for free and can install the operating system on your own server.

In the light of some of the solutions currently available, I think cloud computing will become an alternative to the introduction of computer systems in small and medium enterprises. On the other hand, I think it opens an important market for developers because in these systems integration business in the cloud are fundamental and in many cases service providers do not provide this integration.
