Well, having moved to Digital Ocean, and seeing how wonderful their system is, I have started increasing the number of servers I have with them. I am now hosting a mail server along with the web server I originally migrated from Linode. This will allow Kiss My Creative to provide all the hosting services in house. And the two servers are still cheaper than the one I had originally.
Eventually, growth allowing, I would like to migrate the MySQL service off the web server, to it’s own server, allowing each server to focus on one area of the system. In the mean time though, two should be perfect for what I need.
