I have a site that has many subdomains (one for each client). The content for each subdomain will be different, pulling different data, different layouts etc, so I don't think I can just alias one directory to many different sub domains. My question is, what's the best practice for doing this? Each subdomain will need SSL. My setup is

Amazon EC2 (ubuntu)
Wildcard SSL for my domain (*.mydomain.com)
Apache 2
PHP (LAMP)

Currently, I'm just creating a new entry into "/etc/hosts" and an appropriate spot in the web root (ie /var/www/abc.mydomain.com, /var/www/def.mydomain.com, etc). I've just discovered that I'll need a unique IP for each subdomain, and that's tricky with EC2 as they limit you to the number you can have (unless you jump through some hoops). Right now I have about 10 subdomains, which is manageable, but theoretically I could have thousands.

Am I doing it the only way possible or is there a better way I should investigate?
