Cloud Computing- A brief Introduction

“Do you have to buy a cow if you want milk?”

This question itself will give you some basic idea about the cloud computing. You can use applications installed in a cloud in your day to day needs without buying that application yourself. Think about the Google mail system. It is a cloud, where as you can login to your account and check your mails and you also can open attachments in the browser itself. You don’t need to have Microsoft Word to open a word document which is attached to your email. This is a real life example where you use cloud computing more often. In here the client browser works as the client side of this deal, The server side is the Google Servers. Which might be providing the service for you as a centralized server hosted in more than one country.

Nowadays almost everywhere you can find a Cloud Computing concept. It is the delivery of computing as a service whereby shared resources, software and information are provided to computers and other devices as a metered service over a network. This is the definition Wikipedia gives about the Cloud Computing. Physical location, configuration of the system or end user knowledge does not matter; Cloud Computing provides software, data access, computations and the storage services without them.With the business software and data, stored in the servers at a remote location clients can access them and use applications that they provides using the client side application, such as a Web Browser on a PC, tablet or even in the mobile phone. There are a lot of interesting technologies backing up the server and the client side when manipulating the data or software to present to the clients. In some instances the entire business applications are coded using web based technologies such as Ajax.

Most cloud computing infrastructure consists of services delivered through shared data centers, which appears to the customer as a single point of access for their needs. The client does not necessarily know that he gets the service from various servers geographically located in various countries of the world. But this really helps the information users as well as providers with their time and budget.
