If you Dont Know What is Cloud Computing You must read this..,

Wait.. When i first heard the word "Cloud Computing", i too had a impression that its a very complex field and technology to understand. But when i went through some websites, books and articles i got a clear picture of what the cloud computing is..!! Just read through this article and i strongly believe that your understanding and imagination will change and a
new cloud will have its birth in your mind..!

Okay.. Then What is Cloud Computing..?? Cloud computing is an internet based computing, where by computing resources, information, software, services and other devices are provided to the people or organisations on demand like the electricity grid. Cloud Computing is a paradigm shift from mainframes to client-server architecture in the early 1980's. In Cloud Computing environment there is no need to expertise in or control over the technology infrastructure, which is running the Cloud. That means, let us assume a company is running its own computing infrastructure like Servers, mainframes, datacenters and a team to manage, control and maintain them and there is a need to have their own application softwares for the CRM and other company management. In this case company has to invest a lot of money for maintaining the whole technology infrastructure. But in Cloud Computing environment there will be a company providing all the automation resources, storage , software platforms and other computing resources through internet. And it manages and controls the whole technology infrastructure. The whole complexity and technical risks are abstracted from the users and only the application interfaces are provided to users who can access and run them in the common browsers(Like IE, Google Chrome etc). So as i said, here the term Cloud is used for representing the abstraction from technology infrastructure and the users. In Cloud Computing all the services are given virtually. For your reference few companies providing Cloud Services include Microsoft, Sales Force, Google etc. You can try Free Cloud Services from Google. Google is providing most useful free applications like docs, spreadsheet, presentations, forms and also gives free file storage up to some limit. U will surely get an idea of what is Cloud computing services after using it.
Why to use Cloud Computing services..?
There are so many advantages of it as well as some privacy issues. First of all it abstracts the technical and storage complexity, technology infrastructure management and its up-gradation from users. Getting a Cloud service from any good cloud provider will helps in avoiding the managerial expenses incurred in private infrastructure and the need to train the employees regarding software installation or up-gradation. Its very easy to use a cloud service. Just join any cloud service provider for an annual subscription basis or per resources utilized basis. And the services can be easily accessed using a desktop computer and run on a internet browser. It seems very easier than maintaining the whole Tech infrastructure.
But some companies think that keeping the secret data and other financial corporate data on others's servers is a risky job. Anyway it always depends on the co-operation, faith and the bonding between them.
I hope you understood the basics and liked this introductory post on Cloud Computing. Keep visiting the blog for more information on the subject. I will be posting some more interesting topics which everybody think The most important on the web. If u have any suggestions or any doubts leave a comment. I will reply for it.
