AWS Server Size for Hosting : <p>I am looking into purchasing server space with AWS to host what will eventually be over 50 websites. They will have many different ranges of traffic coming in. I would like to know if anyone has a recommendation on what size of server that would be able to handle this many sites.</p>

<p>Also, I was wondering if it's more cost effective/efficient to host an separate EC-2 instance for each site or too purchase a large umbrella server and host all sites on a single instance?</p>

<p>Thanks,</p>
