In addition to reducing hardware and power expenses, virtualisation allows businesses to run their legacy applications on older versions of an operating system on the same server as newer applications.
Each virtual server can run its own full-fledged operating system and can be independently rebooted.
Partitioning a single server so that it appears as multiple servers has long been common practice on mainframe computers and mid-range computers such as the IBM AS/400. It has become more prevalent with the development of virtualization software and technologies formicrocomputers.

The cloud computing buzz has continued, and 2012 may well be the year when moving application development to the cloud becomes an enticing alternative. Traditional means to manage the complexity of today’s system landscapes increasingly are simply too expensive and time consuming.
Look for cloud application platforms that allow you the option of cloud or on- premise deployment, so as to preserve your options into the future.
Moving to the cloud helps organizations to:
- Reduce total IT spend
- Minimize IT infrastructure expenditure
- Increase IT responsiveness

As part of the Occupy Wall Street (OWS) movement, a team of Web and mobile application developers is redesigning social networking for the era of global protests. The team hopes their technology can go beyond OWS to help establish more distributed social networks, improve online business collaborations, and add to the Semantic Web's development. The Occupy movement already has local networks set up for each occupation site, and the activist-developers are building an overarching, international network called Global Square. A major challenge to all new social networking efforts is ensuring that members are trustworthy. To build trust, local and international networks will use a friend-of-a-friend model. "You have to know someone in real life who sponsors you," says Occupy Movement developer Ed Knutson. Global Square will connect through standards designed to link up disparate technologies. The OWS projects also rely on Open ID and OAuth, which let users sign into new Web sites using their logins and passwords from social networks such as Facebook, Google, and Twitter. In the new OWS technology, an activist's local-occupation network can vouch for a user to another network, and since the local networks all trust each other, they all trust that activist.

The U.S. Is Busy Building Supercomputers, but Needs Someone to Run Them
(12/28/11) Dan Lyons
The United States is rapidly adding to its collection of supercomputers, with new high-performance computing (HPC) systems under development at various labs. However, there are not enough people who know how to make use of all the new supercomputing power, say HPC industry experts. This talent shortage is the "missing middle," meaning there are enough specialists to run the handful of world-beating supercomputers that cost a few hundred million dollars, and plenty of people who can manage ordinary personal computers and servers, but there are not nearly enough people who know how to use the small and midsized HPC machines that cost between $1 million to $10 million. "We need people who can build the applications and algorithms needed to effectively use the equipment," says the University of Tennessee's Jack Dongarra. The Virtual School for Computational Science and Engineering is a program that offers online courses for graduate students who want to learn how to use HPCs. This year, 1,000 students participated, up from 40 in 2008 when the program began, according to National Center for Supercomputing Applications director Thom Dunning.
