First Beowulf Cluster in Space

When a satellite's image-gathering power exceeds the bandwidth available to transmit the images, a Linux cluster right on the satellite helps decide which images to send back to Earth.
Launch into a New Space Era

From an engineer's perspective, X-Sat and its PPU couldn't succeed without Linux: almost all current application developments in the area of remote sensing use Linux, as do most modern cluster systems. So, sometime in early 2007, if you tilt your head back at the right time, you might be caught on camera, processed and downloaded, thanks to Linux.

Ian's been using Linux since about 1856 and weaned his kids at the penguin's electronic teat. His interests include satellites and signal processing, and his career objective is to lose his job and become a missionary in China.

Although Timo didn't try to wean his daughter on the penguin, he uses Linux for most of his number-crunching problems on Beowulf clusters and in the future even more extensively in space. Timo's research focus is remote sensing and various image-processing problems, well, unless he's gone traveling.

Bharath designs high-performance systems for Hewlett-Packard. Not being very high-performance himself, he relies on the pet monkey under his desk to come up with hardware designs. Occasionally, it also writes articles for magazines with penguins on their cover.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
