Our organization currently has 4 sites being run on our EE install. We are looking to add a 5th in the near future. The existing 4 sites are 3 small public sites and one mostly private (intranet) site. This 5th site has the potential to be a much busier and popular site. It is going to be a web version of our primary print publication. It has 80,000 subscribers and in theory they all could visit the site and create accounts (not to mention more who currently do not subscribe to the print publication).
Are there any security issues to be concerned about? Ideally it would of course be best to put this one on its own server, EE install, etc. But is that based on any facts or just paranoia? Security aside, how would such large volumes of traffic effect the other sites on the same install? Would they run measurably slower? Supposing we started on the same install and then saw a need to move to a new server, how hard is it to migrate the member groups/members for this new site? It would have roughly 2,500 entries (every article written over the last 30 years).
While I’m at it…how big can EE sites go? 10,000 entries? 100,000? How many members? I’m sure this largely has to do with how the site is coded and where it is hosted, but I’m curious if there are any inherent isses EE has at a certain point. Given this site has 142,000 members, I’d day its not a problem.
