Paravirtualization With Xen On CentOS 5.4 (x86_64) | HowtoForge - Linux Howtos and Tutorials

falko — Tue, 15 Dec 2009 07:41:00 -0500

This tutorial provides step-by-step instructions on how to install Xen (version 3.0.3) on a CentOS 5.4 (x86_64) system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other, but still use the same hardware.

Setting Up A High-Availability Load Balancer (With Failover and Session Support) With HAProxy/Heartbeat On Debian Lenny | HowtoForge - Linux Howtos and Tutorials

falko — Tue, 14 Jul 2009 05:59:00 -0400

This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy and heartbeat on Debian Lenny. The load balancer sits between the user and two (or more) backend Apache web servers that hold the same content. Not only does the load balancer distribute the requests to the two backend Apache servers, it also checks the health of the backend servers. If one of them is down, all requests will automatically be redirected to the remaining backend server. In addition to that, the two load balancer nodes monitor each other using heartbeat, and if the master fails, the slave becomes the master, which means the users will not notice any disruption of the service. HAProxy is session-aware, which means you can use it with any web application that makes use of sessions (such as forums, shopping carts, etc.).

Paravirtualization With Xen On CentOS 5.3 (x86_64) | HowtoForge - Linux Howtos and Tutorials

falko — Sun, 17 May 2009 12:39:00 -0400

This tutorial provides step-by-step instructions on how to install Xen (version 3.0.3) on a CentOS 5.3 (x86_64) system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one. Tagged by falko under xen, centos, virtualization, paravirtualization, virtual machine,
