As announced in our Cluster Services Built With FOSS post, LinuxForce’s Cluster Services are built exclusively with Free and Open Source Software (FOSS). Here is an expanded outline of the basic architecture of our approach to High-Availability (HA) clustering. Overview In any HA deployment there are two main components: hosts and guests. The hosts are the systems which are the core of the cluster itself. The host runs with very limited services dedicated for the use and functioning of the cluster. The host systems handle resource allocation, from persistent storage to RAM to the number of CPUs each guest gets. The host machines give an “outside” look at guest performance and give the opportunity to manipulate them from outside the guest operating system. This offers significant advantages when there are boot or other failures which traditionally would require phys... (more)

How and Why Contributing to FOSS Can Benefit Your Organization

At first glance, the ecosystem in the Free and Open Source Software (FOSS) world can seem a bit complicated. There are several ways to get software: project websites where you can download it directly, use a software management tool that your Linux distribution provides, or you may also be able to install a Linux distribution that includes everything you need right out of the box! Once you understand this ecosystem, you can find where your contributions would be most useful, and why contributing is beneficial to your organization and the FOSS community. So, where does this all b... (more)

FOSS Linux Virtualization Tools

In January I attended the 10th annual Southern California Linux Expo. In addition to speaking and running the Ubuntu booth, I had an opportunity to talk to other sysadmins about everything from selection of distribution to the latest in configuration management tools and virtualization technology. I ended up in a conversation with a fellow sysadmin who was using a proprietary virtualization technology on Red Hat Enterprise Linux. Not only did he have surprising misconceptions about the FOSS (Free and Open Source Software) virtualization tools available, he assumed that some of the... (more)

Contributing to FOSS: A Business Perspective

Open Web Journal Last weekend I had the pleasure of presenting at the Central Pennsylvania Open Source Conference on the topic of Contributing to FOSS (slides available here). In the talk I explored the many ways individuals can get involved in FOSS (Free and Open Source Software), briefly covering everything from programming to artwork to documentation. As diverse as these contributions are, the common thread is close collaboration with the project itself. In particular, following the procedures in place for contributing to the project is essential. The talk also reviewed some... (more)

Given 250,000 Tools on the Shelf, How Do You Manage Them?

Although I haven’t seen a thoroughly researched study, I figure there must be at least 250,000 FOSS (Free and Open Source Software) tools available to every systems administrator on the planet (230,000 at SourceForge + 15,000 at Launchpad + 12,000 at CodePlex + 5,000 at Google Code and that doesn’t count the Linux kernel or any of the myriad other self-hosted projects). These 250,000+ resources comprise the full “toolbox” that admins can use for building solutions with FOSS; they represent the FOSS equivalent of COTS (Commercial Off-The-Shelf). Of course, if you add open source b... (more)
