Create a Mini PC or Server with Olimex's Olinuxino A13/A13Micro

Olimex is a Bulgarian company known for its innovative hobbyist products. It has a wide array of microcontroller-based products, ranging from the small Arduino clones to the very able system that has the Allwinner A13 microcontroller as its brain. In this article, I describe how you can create a working Linux system for the Olinuxino A13 and Olinuxino A13Micro from scratch. more>>

Protect Your Ports with a Reverse Proxy

In a previous article, I discussed Apache Tomcat, which is the ideal way to run Java applications from your server. I explained that you can run those apps from Tomcat's default 8080 port, or you can configure Tomcat to use port 80. But, what if you want to run a traditional Web server and host Java apps on port 80? The answer is to run a reverse proxy. more>>

Advanced Hard Drive Caching Techniques

With the introduction of the solid-state Flash drive, performance came to the forefront for data storage technologies. Prior to that, software developers and server administrators needed to devise methods for which they could increase I/O throughput to storage, most of which resulted in low capacity caching to random access memory (RAM) or a RAM drive. more>>

Consolidate: Put Your Servers into a VirtualBox VM

Rather than installing a server, such as a web server, directly onto your main computer, why not install it in a VM? This sort of setup has a few advantages of security and convenience. These days, spreading resources out into the cloud is the in-thing, but consolidation is often underexploited. Hosting a server in a virtualizer such as VirtualBox is often a good approach for casual or occasional server needs on a home network. more>>

Using an SMS Server to Provide a Robust Alerting Service for Nagios

I’m a big fan of the Nagios network monitoring system and rely on it to tell me if something goes wrong with the systems for which I am responsible. I have made a large investment in time configuring Nagios to monitor exactly what I am interested in, and this effort would be wasted if Nagios detected a problem, but failed to communicate that problem to me. more>>

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.
