In my last project at work, I had to replace NFS with GFS2 and Clustering. So in this tutorial I will show you how to create a Red Hat or CentOS cluster with GFS2. I will also show you how to optimize GFS2 performance in the next HowTo, because you will quickly notice some loss of performance until you do a little optimization first.I will 1st show you how do build a Cluster with GFS2 on the Command Line and in the next tutorial I will show you how to do the same thing using Conga.

oud applications, computing, and storage are just emerging on the scene, yet there is a rapid heightening of interest in all things cloud. Google and Amazon popularized the concept, now businesses of all sizes and types are interested in its potential. With the availability of cloud storage-enabling solutions, many service providers and hosting companies are investigating new cloud storage service offerings.
Windows/Mac/Linux: Inspired by our post on Linux backup utility Back in Time, but finding it lacking encryption and network powers, Rob Oakes wrote his own Python-based utility to back up Windows, Mac, or Linux machines across local machines or networks.
Cloud computing means you can store your data in web applications and access it from any browser, anywhere—but that doesn't mean you don't need a backup plan. Safeguard your data when a storm's a-brewing in the cloud with these tools.

From early in their company's history, Google's founders, Larry Page and Sergey Brin, wanted to develop a computer operating system and browser. Credit: Brian Stauffer They believed it would help make personal computing less expensive, because Google would give away the software free of charge. They wanted to shrug off 20 years of accumulated software history (what the information technology industry calls the "legacy") by building an OS and browser from scratch. Finally, they hoped the combined technology would be an alternative to Microsoft Windows and Internet Explorer, providing a new platform for developers to write Web applications and unleashing the creativity of programmers for the benefit of the masses.
SUSE Studio is a free, web-based service designed to build virtual appliances, such as pre-installed hardware-appliances, or "software appliances" -- pre-configured Linux server stacks suitable for installation by users on real or virtual commodity hardware. Recently released from beta, SUSE Studio can produce appliance images in raw disk image, Live CD/DVD iso, VMware, and Xen formats, and there are plans in the works for supporting Amazon's EC2 ami format, says the review by our sister publication, eWEEK.
The time has come to declare that the beginning of the end for the traditional approach to Information Technology. The party is over. The End of IT 1.0 As We Know It – has begun. To borrow a phrase from my previous IBM colleagues who wrote, “The End of TV As We Know It” with which I became familiar while working on IP Television (IPTV).
The White House may decide to make NASA its pilot project for replacing the government’s current IT infrastructure with cloud computing. According to NASA’s associate chief information officer for architecture and infrastructure, Mike Hecker, NASA officials have ”broached the idea of NASA becoming an IT service provider. NASA as an IT service provider takes us into a new realm.” But also said that, “We’re still debating if that’s a good idea or not.”
Virtual Bridges partners with IBM and Canonical for Microsoft-free “Desktops in the Cloud” This groundbreaking partnership combines the most popular Linux distribution, Ubuntu, with the IBM suite of enterprise-class applications and services, including Symphony, Sametime and Notes, together with Virtual Bridges’ end-to-end, top-to-bottom pure Linux-based VDI offering, VERDE (Virtual Enterprise Remote Desktop Environment).
Lesser Privacy Protection Under the Law To search your house or office (including documents stored on your computer's hard drive), cops need to obtain a search warrant. To get to the information you've stored on a third-party's web servers, they only need a subpoena, which is easier to obtain. This kind of search can also happen without your knowledge.
It’s clear Google and Amazon wouldn’t be where they are today without the use of open source software,” said Stevens. The Google Inc. and Amazon.com Inc. success stories were also echoed by Aslett, who said both public cloud platforms benefited from low cost licencing and flexibility, as well as the ability to empower their developers. “For Google, it’s about ability to make changes to their operating system without having to ask anybody’s permission or pay for client licence fees,” he said, adding that development times are also speed up in the process.
"They're doing a variety of things, but a lot of them are basically interested in Eucalyptus for doing the same kinds of things they're doing in Amazon AWS, such as business logic applications, where part of the attraction of Eucalyptus is that they can use it as a platform for seamlessly running their public cloud applications and their on-premise cloud apps."
DiscCloud demonstrates Virtual Mac "Desktop in the Cloud" running concurrent Flash, Quicktime, iTunes, Youtube, Keynote and Pages, and Safari applications. The realtime performance demo took place over an Internet connection spanning 800 miles, and 16 hops, accessed by an 8 year old iMac (PowerPC) with 512MB RAM.. See the live video on DiscCloud!

ordle is a toy for generating “word clouds” from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text. You can tweak your clouds with different fonts, layouts, and color schemes. The images you create with Wordle are yours to use however you like. You can print them out, or save them to the Wordle gallery to share with your friends.
