I am migrating from a vps based hosting to a dedicated hosting (8GB RAM/1TB HD). I need to run multiple Drupal and Ruby based applications? what would be the recommended configuration. I was thinking of two options.
1) Install multiple Debian os on top of Xen (like VPS). Each may be 2GB Memory and run Drupal and Ruby and MYSQL on separate partitions .
2) Install one instance of Debian. and Install Drupal (Apache, php) Ruby (lighttpd, ruby) ,MySQL all in the same partition
I was little worried that option 2 could lead to some performance issues later..
