Well, everybody's talking about Beowulf, about High Availability. But nobody dares to talk about MOSIX, a Linux Kernel Module developed at an Israel University. It supports things like application-transparent adaptive load balancing, memory ushering and things like that. The only problem: not free up to now. But, wait! They are currently looking for a sponsor for maintainance and further development. This sponsor(s) may also choose the license, too. Check this one: MOSIX Homepage. Tried to post it to slashdot wo times before, but they didn't seem to like it ... :(
Eddieware does DNS load balancing (and hence isn't bottlenecked like the Linux Virtual Server Project), LAN load balancing, IP migration and admission control. In addition to linux 2.0.x and 2.2.x it works under FreeBSD and Solaris. Checkout http://www.eddieware.org .
Checkout the Eddieware press release at www.eddieware.org/txt/press990503.html . Funny how this didn't get a mention in the main slashdot articles but a closed source solution does!
As the other reply says, our main target is going to be business customers. If you can grab the kernel patch, recompile your kernel, etc.. you don't buy commercial software.. you probably also work for a company that pays you enough that maybe the time it takes you to do that costs more than the software :) The point is that our software is commercially developed and supported, we make it easier to manage and easier to implement, and take care of some of the work that would cost our customers time and money on our end..

As far as a GPLed monitor and config, it isn't just a 'monitor and config', it is a cluster daemon that does load balancing and offers up faul-tolerance, etc.. Let's also pay attention to 'TurboLinux has not announced Licensing for the monitoring and configuration portions', this means we are looking at different licensing models, it doesn't mean we are definitely going to close the source.. stay tuned for our decision, we aren't out to chet the Linux world, we just want people to buy our stuff.
FYI part of the config is opensourced, the module to TurboNetCfg that sets up the cluster webserver is open-sourced (the beta download is approx 120k I think, it has the kernel patch, tlcusteradm, tlcusterd, and the module for NetCfg, check it out)
Free Software is a great thing, but so is paying the bills, it can be hard to find a balance. This is not a product that would sell in the numbers that the others will, and it requires *much* more development work than the core distribution, so it is more costly.
If you have suggestions on any of our products, comments, etc.. let me know, my e-mail is justin@turbolinux.com, I'm a Developer Relations Associate with PHT and beleive me, we really do care
Later,
Justin
