Move running virtual machines from one physical server to another with no impact to end users

The emergence of the networked information economy is unleashing two powerful forces. On one hand, easy access to high-speed networks is empowering individuals. People can now discover and consume information resources and services globally from their homes. Further, new social computing approaches are inviting people to share in the creation and edification of information on the Internet. Empowerment of the individual-or consumerization-is reducing the individual's reliance on traditional brick-and-mortar institutions in favor of new and emerging virtual ones. Second, ubiquitous access to high-speed networks along with network standards, open standards and content, and techniques for virtualizing hardware, software, and services is making it possible to leverage scale economies in unprecedented ways. What appears to be emerging is industrial-scale computing-a standardized infrastructure for delivering computing power, network bandwidth, data storage and protection, and services. Consumerization and industrialization beg the question "Is this the end of the middle?"; that is, what will be the role of "enterprise" IT in the future? Indeed, the bigger question is what will become of all of our intermediating institutions? This volume examines the impact of IT on higher education and on the IT organization in higher education.

The multi-faceted Cloud market is chugging along; some components are ballooning, while others crawl.

Imagine that a Singapore-based sales manager is accessing a CRM application which was once local, but is now based in the Hong Kong data center. But it's end of quarter and the peak load on the Hong Kong CRM application is over the specified capacity limit, so the transaction (running on a virtual machine) is transferred via VMotion to the data center in San Francisco, completed and sent back to the Singapore sales office.

Cloud computing is a consumer/delivery model where information technology (IT) capabilities are offered as services billed based on usage and has brought big data analysis to the masses by giving businesses access to vast amounts of computing resources on demand.

Although Server-based computing incurs capital costs, but it can offer the best computing environment for the users. Actually, the server based computing offers the IT managers with much secured, manageable and effective computing model.
