Penguin Computing announced the debut of what it calls Penguin on Demand - POD, for short - a service that offers remote access to high-performance computing (HPC) Linux clusters.

Clearly, the underlying technology of cloud computing will be based on open source software--that is, if the three cloud infrastructure hopefuls addressing a standing room-only crowd of more than 350 venture capital firms, large company CTOS and CIOs, and other cloud hopefuls--are as successful in their efforts as the show’s judges and audience anticipated.

These days, everybody is talking about cloud computing, and many people use it in one form or the other. But popular cloud computing services are provided by a third party, which means that you store you data on a server somewhere, so that you can access it any time, from anywhere. But there are cloud applications that any person can use to host their own private cloud, from their home.

The total number of dollars rushing toward cloud computing is massive. The various top research firms - IDC, Gartner, et al. -- all have eyebrow-raising forecasts about the growth rate of cloud-based computing services. But are you seeing a lot of headlines about safety? No, not really, though the worries are out there.

The Climate Savers Computing Initiative is on the front lines of the battle against global climate change. Their mission? To convince you that saving power is good for both Mother Earth and the bottom line. The Green Penguin chats with Pat Tiernan, Climate Savers' new executive director, to see what the future holds for this green-IT organization.

"Cloud Computing risks undoing the gains of the free software movement in ‘owning and controlling our own code‘. Thomas Lord examines the potential for achieving software and user freedom in the world of ‘cloud computing’ (a concept he rejects, preferring ‘utility computing’, see below).

Cloud computing and storage convert physical resources (like processors and storage) into scalable and shareable resources over the Internet (computing and storage "as a service"). Although not a new concept, virtualization makes this much more scalable and efficient through the sharing of physical systems through server virtualization.

2010 is definitely the year of the cloud, The IT world is abuzz with the benefits of cloud computing and rightfully so. Cloud computing, the logical extension of network storage and virtualization, is probably the biggest IT leap forward since pervasive use of the Internet. Despite the buzz all that glitters isn’t gold.

Penguin Pete gets into the fairytales... welocome to the computing republics of Windows, Apple, and Unix; all ruled in remarkably different ways.
