Re: ESX Vmware Physically connected to different segments



Ah.

I misunderstood your business.

In a situation like this, I don't think you have a choice, though I
don't have enough experience in such a situation to comment
coherently.

I was envisioning the servers being at the client site, and that you
were using virtualization for hosts that were both in the DMZ and the
internal network(s), and that's what I was preaching against.

Just the fact that we mix customers in a virtual environment creates a
similar risk. We aren't able to offer a dedicated host for every
customer who wants a virtual environment, that would defeat the purpose
of virtualization.

Maybe I missed part of the earlier discussion, and I'm always ready to
look at other ways of approaching the problem. Other than dedicated
hosts for each customer, what would you suggest a basic design be to
provide what you are describing?

There are other ways of hosting internet-exposed sites, and I believe
you are doing your customers a disservice by mixing domains in this
fashion, which (IMHO) exposes them to unnecessary risk.
