[TriLUG] Hosting multiple WordPress sites - VMWare or OpenVZ

[Warren Myers]

First, a VPS *is* a VM - its jut one you are renting from somebody :)

I'm only familiar with VMware, and can't say enough good things about it -
if you can afford the licensing :)

and create a VPS container for each customer.  Since we already have VMWare
deployed in the infrastructure, installing CentOS/LAMP in a VM with
apache's virtual hosting was my first choice.

VPS containers seem more secure, but I am less familiar with the OpenVZ
environment.  I also understand performance issues in one VPS container is
not supposed to affect other containers.  However, customers running inside
the same VM will definitely get affected by a rogue site.

to host many WordPress sites; I just need to find the right OS "container"
to host them.
