Network Storage Device
As many have emphasized, Linux is exceptional in the server market. For consumers however, many do not realize servers can be very small scale and reduced to embedded devices. I’ve been working on a Linksys Network Storage Device for my home lan. Basically the device is a Linux server running on 133Mhz ARM Processor with 32MB of ram. However it comes with a 100Mbit network port and 2 individual USB2.0 ports.
Virtual Private Servers
One of Linux’s many strength’s is its highly suitable web hosting options. Primarily Apache web server on Linux with various open source applications can provide cheap solutions for hosting needs. The most commonly used hosting option is Virtual Hosting through Apache. With a simple setup, hundreds of unique websites can be run with 1 single server machine. For about $100 (US) a year, you can get a good set of features from most providers.
