Determining your need
How does one determine how much resources they need? Hard drive space and bandwidth is easy enough if you have logs, but how do you determine how much memory or how much CPU?
I'm in the process of moving from a shared host to a VPS. I run four relatively small websites:
1. Personal website on Drupal 6* with quite a few modules. Hosts 3 podcasts. Get's about 15-25 GB/month bandwidth.
2. Moodle site for a non-profit agency. About 600 users are required to take a
3. 2 small Wordpress sites.
Once I've moved I would like to migrate the Drupal site to Wordpress.
Total disk space is currently about 6 GB.
The plan is nginx, mysql, php-fpm. I've been running Linux at home for 8 years including a headless server running lighttpd and dovecot, so admin without a panel shouldn't be problem.
