The Linux Virtual Server is a highly scalable and highly available server built on a cluster of real servers, with the load balancer running on the Linux operating system. The architecture of the server cluster is fully transparent to end users, and the users interact as if it were a single high-performance virtual server. For more information, click here.
The Linux Virtual Server as an advanced load balancing solution can be used to build highly scalable and highly available network services, such as scalable web, cache, mail, ftp, media and VoIP services.
This site hosts the Linux Virtual Server kernel patches and related programs, released under the GNU General Public License (GPL). This site also provides various information about the Linux Virtual Server cluster: how it works, how to use it, and its ongoing development.
