• PHP-FPM/Nginx Security In Shared Hosting Environments (Debian/Ubuntu)
  If you want to use nginx and PHP-FPM for shared hosting environments, you should make up your mind about security. In Apache/PHP environments, you can use suExec and/or suPHP to make PHP execute under individual user accounts instead of a system user like www-data. There's no such thing for PHP-FPM, but fortunately PHP-FPM allows us to set up a "pool" for each web site that makes PHP scripts execute as the user/group defined in that pool. This gives you all the benefits of suPHP, and in addition to that you don't have any FTP or SCP transfer problems because PHP scripts don't need to be owned by a specific user/group to be executed as the user/group defined in the pool.

• Setting Up A High-Availability Load Balancer (With Failover and Session Support) With HAProxy/Heartbeat On Debian Etch
  This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy and heartbeat on Debian Etch. 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
