The LVS (Linux Virtual Server) project was launched in 1998 and is meant to eliminate Single Point of Failures (SPOF). According to the linuxvirtualserver.org website: “LVS is a highly scalable and available server built on a cluster of real servers, with the load balancer running on Linux. The architecture of the server cluster is fully transparent to the end user, and the users interact as if it were a single high-performance virtual server. The real servers and the load balancers may be interconnected by either a high speed LAN or by a geographically dispersed WAN.”

Tightening up OpenSSH
Often I am required required to run a public ssh server, so its a good idea to restrict the OpenSSH server as much as possible.

Building A Highly Available Nginx Reverse-Proxy Using Heartbeat
A cluster in computing is a term used to describe a group of closely linked computers often appearing as a single entity to the outside world. There are various types of clusters—high-availability (HA) clusters, load-balancing clusters, compute clusters or high performance computing (HPC) clusters and grids.

Building A Highly-Available Web Server Cluster
nginx (pronounced as ‘engine x’) is a powerful HTTP Web server/reverse proxy and IMAP/POP3 reverse proxy. According to a survey conducted in December 2008 by Netcraft, nginx has grown significantly and has surpassed lighttpd (also known as Lighty). Because of its small memory footprint and high scalability, nginx has found tremendous usage in virtual private servers (VPS).
