Experience the Cloud Computing by Flying Into the Cloud..Just Follow the steps to Set up your own private cloud system using   Ubuntu Enterprise Cloud (UEC) , which is powered by the   Eucalyptus platform . The system is made up of one cloud controller (also called a front-end server) and one or more node controllers. The cloud controller manages the cloud environment. You can install the default Ubuntu OS images or create your own to be virtualized. The node controllers are where you can run the   virtual machine (VM)   instances of the images. System Requirements At least two computers must be dedicated to this cloud for it to work: One for the front-end server (cloud or cluster controller) with a minimum 1GHz CPU, 512MB of memory, CD-ROM, 40GB of disk space, and an Ethernet network adapter One or more for the node controller(s) with a CPU that supports Virtualization Technology (VT) extensions, 1GB of memory, CD-ROM, 40GB of disk space and an Etherne...

  This is the forth post in the cloud computing series, in this post we will be discussing further about cloud computing. The previous posts related to cloud computing are listed as follows: The power of cloud (Introduction to Cloud Computing) The architecture of cloud computing. Cloud computing Applications   Perhaps the biggest concerns about cloud computing are security and privacy . The idea of handing over important data to another company worries some people. Corporate executives might hesitate to take advantage of a cloud computing system because they can't keep their company's information under lock and key. The counterargument to this position is that the companies offering cloud computing services live and die by their reputations. It benefits these companies to have reliable security measures in place. Otherwise, the service would lose all its clients. It's in their interest to employ the most advanced techniques to protect their clients' d...

When talking about a cloud computing system, it's helpful to divide it into two sections: the front end and the back end . They connect to each other through a network , usually the Internet . The front end is the side the computer user, or client, sees. The back end is the "cloud" section of the system. The front end includes the client's computer (or computer network) and the application required to access the cloud computing system. Not all cloud computing systems have the same user interface. Services like Web-based e-mail programs leverage existing Web browsers like Internet Explorer or Firefox . Other systems have unique applications that provide network access to clients. On the back end of the system are the various computers, servers and data storage systems that create the "cloud" of computing services. In theory, a cloud computing system could include practically any computer program you can imagine, from data processing to video ga...

Let's say you're an executive at a large corporation. Your particular responsibilities include making sure that all of your employees have the right hardware and software they need to do their jobs. Buying computers for everyone isn't enough -- you also have to purchase software or software licenses to give employees the tools they require. Whenever you have a new hire, you have to buy more software or make sure your current software license allows another user. It's so stressful that you find it difficult to go to sleep on your huge pile of money every night. Soon, there may be an alternative for executives like you. Instead of installing a suite of software for each computer, you'd only have to load one application. That application would allow workers to log into a Web-based service which hosts all the programs the user would need for his or her job. Remote machines owned by another company would run everything from e-mail to word processing to ...
