About Cloud Computing
"Cloud computing" is becoming increasingly in vogue in the IT world today. It doesn`t have a totally accepted definition, but several versions of what appears to be a new era in information technology.
The cloud is a well known metaphor of the Internet, a familiar cliche that combined with the word "computing" rises expressions which may seem grandiose to some or only a nebula, mostly for others. In fact, cloud computing should not suggest simplicity.
One of the cloud computing definition could be: a solution using external resources (servers, storage space, applications and services) via Internet.
Others may compare cloud computing to an electricity grid that you connect to and pay on demand. In other words, what you do not use, you do not pay.
Before and after cloud computing…
Traditional economic applications require very different conditions, making them too unmanageable and too expensive for small companies. They require space, network bandwidth, storage capacity, etc.. And a team of experts to install and configure them.
With "cloud computing", business management becomes much easier. Instead of managing your own computer network, you can address to a data center where your applications are stored. Using an application "in the clouds" means logging in, customizing and using it. You get the most of the final service without taking many other actions to achieve the desired purpose. This is the power of cloud computing.
Cloud computing solutions save money for servers, software licenses, hosting, collocation, maintenance or ultra specialized technical personnel. They cost less because they do not use many resources. And it seems that they are more scalable and more reliable than most of applications. In addition, cloud applications get automatic upgrades, so they are efficient and have new functionalities without any effort on your part.
The secret is the technology that leads to the existence of applications that can be accessed from "the clouds". These are applications that run entirely over the Internet and have a high degree of interactivity with the users (Rich Internet Applications). Due to cloud computing, even small or medium businesses that do not afford an IT infrastructure or an investment in expensive software, can use the world's most important technologies, just like multinational companies, but now at the lowest costs.
Even the method of payment for these applications is entirely changed. Forget about servers and licenses. When your application runs in "the clouds", you don`t have to purchase anything. It all comes down to a monthly subscription, which includes everything that you need.
Extending the concept of cloud computing has also led to the extension of another phenomenon: SaaS (Software as a Service). This means that the days of " the license" as we know it, are almost gone. And to deliver browser applications to thousands of users will be viewed as a service performed on a monthly subscription basis. For customers, this means the lack of an initial investment in infrastructure or software, and for vendors low costs in maintaining and developing such applications. Cloud computing does not require additional IT resources and it focuses the attention of companies and investors on developing new projects and on innovation. Accessing applications stored "in the clouds" on virtual servers can be considered a simple idea, but with a major impact on your business.
